I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange proposes to (1) amend Rules 7.36 and 7.37 to add the 
designated market maker (``DMM'') as a Participant for trading of 
Exchange-listed securities on Pillar; (2) amend Rule 7.31 to add 
Auction-Only Orders and make related changes; (3) add new trading rules 
relating to auctions for Pillar; (4) make conforming amendments to 
Rules 1.1, 7.11, 7.12, 7.16, 7.18, 7.32, 7.34, and 7.36; and (5) amend 
the preambles on current Exchange rules relating to their applicability 
to the Pillar trading platform. The proposed rule change is available 
on the Exchange's website at www.nyse.com, at the principal office of 
the Exchange, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the self-regulatory organization 
included statements concerning the purpose of, and basis for, the 
proposed rule change and discussed any comments it received on the 
proposed rule change. The text of those statements may be examined at 
the places specified in Item IV below. The Exchange has prepared 
summaries, set forth in sections A, B, and C below, of the most 
significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and the 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange proposes to (1) amend Rules 7.36 and 7.37 to add the 
DMM as a Participant for trading of Exchange-listed securities on 
Pillar; \4\ (2) amend Rule 7.31 to add Auction-Only Orders and make 
related changes; (3) add new trading rules relating to auctions for 
Pillar; (4) make conforming amendments to Rules 1.1, 7.11, 7.12, 7.16, 
7.18, 7.31, 7.34, and 7.36; and (5) amend the preambles on current 
Exchange rules relating to their applicability to the Pillar trading 
platform.
---------------------------------------------------------------------------

    \4\ ``Participant'' is defined in Rule 7.36(a)(5) to mean, for 
purposes of parity allocation, a Floor broker trading license (each, 
a ``Floor Broker Participant'') or orders collectively represented 
in the Exchange Book that have not been entered by a Floor broker 
(``Book Participant'').
---------------------------------------------------------------------------

    Currently, the Exchange trades UTP Securities on its Pillar trading 
platform, subject to Pillar Platform Rules 1P-13P.\5\ In the next phase 
of Pillar, the Exchange proposes to transition trading of Exchange-
listed securities to the Pillar trading platform.\6\ Once transitioned 
to Pillar, such securities will also be subject to the Pillar Platform 
Rules 1P-13P.
---------------------------------------------------------------------------

    \5\ ``UTP Security'' is defined as a security that is listed on 
a national securities exchange other than the Exchange and that 
trades on the Exchange pursuant to unlisted trading privileges. See 
Rule 1.1.
    \6\ The Exchange has announced that, subject to rule approvals, 
the Exchange will begin transitioning Exchange-listed securities to 
Pillar on July 15, 2019, available here: https://www.nyse.com/publicdocs/nyse/markets/nyse/NYSE_Pillar_Update_NGW.pdf. The 
Exchange will publish by separate Trader Update a complete symbol 
migration schedule.
---------------------------------------------------------------------------

    As provided for under current Rule 103B, all Exchange-listed 
securities are assigned a DMM, and when such securities transition to 
trading on Pillar, the assigned DMM will continue to be responsible for 
such securities. Accordingly, the Exchange proposes to amend the Pillar 
rules to add the DMM as a Participant under the Pillar Platform Rules. 
In addition, because the Exchange conducts auctions for Exchange-listed 
securities, with this proposed rule change, the Exchange proposes 
Pillar rules relating to auctions.
Overview
    DMM as Parity Participant. Under current Exchange rules, executions 
in Exchange-listed securities are allocated based on parity by 
individual participants. Pursuant to Rule 72(c)(ii), the individual 
participants for purposes of share allocation in such executions are 
each single Floor broker, the DMM, and orders collectively represented 
in Exchange systems (referred to in Rule 72(c) as the ``Book 
Participant''). In Pillar, executions in UTP Securities are similarly 
allocated based on parity by individual participant, which are 
currently individual Floor brokers (each, a ``Floor Broker 
Participant'') and the Book Participant.\7\ The Exchange proposes that 
when Exchange-listed securities transition to Pillar, executions of 
Exchange-listed securities will continue to be allocated based on 
parity by individual participants, which will include the DMM assigned 
to a security as a Participant.
---------------------------------------------------------------------------

    \7\ See Rules 7.36 and 7.37.
---------------------------------------------------------------------------

    Auctions. Currently, auctions in Exchange-listed securities are 
governed by a myriad of rules: Rule 15 (Pre-Opening Indications and 
Opening Order Imbalance Information); Rule 115A (Orders at Opening); 
Rule 116.40 (``Stopping'' stock on market-on-close orders); Rule 123C 
(The Closing Procedures); and Rule 123D (Openings and Halts in Trading) 
(collectively, the ``Current Auction Rules'').
    With the transition of Exchange-listed securities to Pillar, the 
technology underpinning auctions on the Exchange would change, but 
auctions for Exchange-listed securities would function largely the same 
as under the Current Auction Rules, subject to specified differences, 
described below. Specifically, DMMs would continue to be responsible 
for facilitating openings, reopenings,\8\ and the close of trading, as 
required by Rules 104(a)(2) and (3), and both Limit Orders priced 
better than the auction price and Market Orders would

[[Page 6869]]

continue to be guaranteed to participate in such auctions.\9\ The 
Exchange also proposes to continue disseminating the same order 
imbalance information content in advance of auctions on the Exchange.
---------------------------------------------------------------------------

    \8\ The Exchange proposes that its Pillar rules would use the 
term ``reopening'' rather than the hyphenated term ``re-opening.'' 
Accordingly, new proposed rules would use the term ``reopening,'' 
and in this filing, the Exchange proposes to replace the term ``re-
opening'' with the term ``reopening'' in Rules 7.11 and 7.31(c).
    \9\ See Rules 115A(a) and 123C(7).
---------------------------------------------------------------------------

    With the move to Pillar, the Exchange proposes to use standardized 
Pillar terminology to describe auctions on the Exchange. Accordingly, 
for Pillar auctions, the Exchange proposes the Rule 7.35 Series 
(Auctions), which would be set forth under Rule 7P as proposed Rule 
7.35 (General), proposed Rule 7.35A (DMM-Facilitated Core Open and 
Trading Halt Auctions), proposed Rule 7.35B (DMM-Facilitated Closing 
Auctions), and proposed Rule 7.35C (Exchange-Facilitated Auctions) 
(collectively, the ``Pillar Auction Rules''), which would replace the 
Current Auction Rules. The proposed rules would include new terminology 
specific to the Exchange as well as text that is based on Pillar 
terminology used by its affiliated exchanges that also operate 
auctions, NYSE Arca, Inc. (``NYSE Arca'') and NYSE American LLC (``NYSE 
American'').
    Except for specified differences described below, the Pillar 
Auction Rules are substantively based on the Current Auction Rules. 
However, the text for the Pillar Auction Rules would in many cases be 
new to the Exchange as compared to the Current Auction Rules.
    The Exchange proposes to include a preamble to each of the Current 
Auction Rules that would provide that each such rule would not be 
applicable to trading on the Pillar trading platform. The Exchange 
believes that this preamble will promote transparency in Exchange rules 
that the Current Auction Rules would not be applicable to auctions on 
Pillar, and is consistent with preambles on other Exchange rules that 
specify that such rules are not applicable to trading on the Pillar 
trading platform.
    Orders and Modifiers. Rule 13(c) specifies the Auction-Only Orders 
currently available for auctions in Exchange-listed securities. Rule 
7.31(c) defines Auction-Only Orders that the Exchange accepts in UTP 
Securities, which are routed to the primary listing market. The 
Exchange proposes to amend Rule 7.31(c) to specify in Pillar rules the 
Auction-Only Orders that would be available for Exchange-listed 
securities to participate in auctions on the Exchange. The Exchange 
does not propose any differences to the order types that would be 
available, but proposes to use Pillar terminology to describe these 
order types.
    The Exchange further proposes to amend Rule 7.31 to specify which 
order types would not be eligible to participate in an auction.
    Related Rule Changes. To address how auctions would impact other 
Pillar rules and to support the transition of Exchange-listed 
securities to Pillar, the Exchange proposes related rule changes to the 
following Pillar Platform Rules 1.1 (Definitions), 7.11 (Limit Up--
Limit Down Plan and Trading Pauses in Individual Securities Due to 
Extraordinary Market Volatility), 7.12 (Trading Halts Due to 
Extraordinary Market Volatility), 7.16 (Short Sales), 7.18 (Halts), 
7.32 (Order Entry), 7.34 (Trading Sessions), and 7.36 (Order Ranking 
and Display).
    Updates to Rule Preambles. To support the transition of Exchange-
listed securities to trading on Pillar, the Exchange further proposes 
to amend the preambles to certain current rules to remove references to 
UTP Securities so that those preambles would provide that ``This Rule 
is not applicable to trading on the Pillar trading platform.'' \10\ 
There are certain non-Pillar rules that would continue to be applicable 
to trading of Exchange-listed securities on the Pillar trading 
platform. For those rules, the Exchange does not propose to amend the 
existing preamble.
---------------------------------------------------------------------------

    \10\ The Exchange proposes to make this change to Rules 4, 7, 
12, 13, 14, 15, 15A, 19, 51, 52, 55, 56, 60, 61, 62, 67, 70, 71, 
79A, 80C, 115A, 116, 123B, 123C, 123D, and 128. The Exchange 
proposes that paragraph (d) of Rule 123D, which provides for an 
Initial Listing Regulatory Halt, would continue to be applicable. 
Accordingly, the preamble for that rule would provide ``[e]xcept for 
paragraph (d), this Rule is not applicable to trading on the Pillar 
trading platform.''
---------------------------------------------------------------------------

Summary of Substantive Differences
    As noted above, when transitioning its trading platform for 
Exchange-listed securities to Pillar, auctions on the Exchange will 
continue to function largely the same as under the Current Auction 
Rules. However, in moving to a new trading platform, the Exchange has 
identified specified enhancements to how auctions would function. 
Certain of these enhancements are available because the Exchange 
proposes to avail itself of existing Pillar functionality available on 
its affiliated exchanges. Other enhancements are specific to how 
Exchange auctions would function. These changes are described in 
greater detail below.
    The following provides a high-level summary of certain of the 
substantive differences that the Exchange proposes to how its auctions 
would function on Pillar as compared to how auctions function under the 
Current Auction Rules:
     The Exchange proposes to determine the Official Closing 
Price for Exchange-listed securities in the same manner as such price 
is determined on NYSE Arca and NYSE American. Namely, if there is no 
auction of a round-lot or more, the Official Closing Price would be 
based on the most recent consolidated last-sale eligible trade, rather 
than on the most recent last-sale eligible trade on the Exchange.
     The reference price for openings and reopenings would be 
the most recent consolidated last-sale eligible trade after 9:30 a.m. 
on a trading day, and if none, the Official Closing Price for the 
security, rather than the last sale price on the Exchange.\11\
---------------------------------------------------------------------------

    \11\ All times in the Pillar Auction Rules are Eastern Times. 
The Exchange proposes to amend Rule 1.1(d), the definition of Core 
Trading Hours, to add that ``[a]ll times in the Pillar Platform 
Rules are Eastern Time.'' With this proposed amendment, the Exchange 
proposes that the remaining Pillar rules would not repeat the term 
``Eastern Time'' next to time references and proposes to delete 
references to that term in Rule 7.34.
---------------------------------------------------------------------------

     Auction Imbalance Information made available over the 
Exchange's proprietary data feeds, which is referred to as Order 
Imbalance Information under the Current Auction Rules, would be updated 
every second (rather than in five-minute, one-minute, or five-second 
intervals as under the Current Auction Rules), would begin for the open 
at 8:00 a.m. rather than 8:30 a.m., and would continue to be published 
until the applicable Auction begins. This would be new for the close as 
currently, the Exchange stops publishing Order Imbalance Information at 
4:00 p.m.
     The reference price used for determining whether to 
publish a pre-opening indication for securities that have limited 
publicly-available pricing information available would be a derived 
last sale price.
     Orders with immediate-or-cancel time-in-force instructions 
would no longer be eligible to participate in opening or reopening 
transactions and Primary Pegged Orders would no longer be eligible to 
participate in the close.
     Any Floor broker interest represented orally at the close 
must include a limit price, and would no longer be permitted to be 
entered ``at the market,'' and Floor brokers, rather than the DMM, 
would be responsible for electronically entering the details of such 
orders for participation in the closing auction, subject to DMM 
validation. Because, as noted above, the Exchange would continue 
publishing Auction Imbalance Information until the security closes, any 
such Floor broker oral interest would be included in the Auction 
Imbalance Information once it has been electronically entered.

[[Page 6870]]

     The Exchange would publish its Regulatory Closing 
Imbalance, referred to as the Mandatory MOC/LOC Imbalance Publication 
under the Current Auction Rules, at the specified time, regardless of 
whether a security is halted at that time.
     During a halt or pause in Exchange-listed securities, 
orders not eligible to participate in the reopening would be cancelled 
rather than kept on the Exchange Book.
     If the Exchange facilitates an Auction, such auction would 
continue to be subject to price limitations and not all orders would be 
guaranteed to participate, as provided for under the Current Auction 
Rules, but the Exchange would determine how to price such auction based 
on functionality available for electronic auctions on NYSE Arca and 
NYSE American and will apply extension logic for reopenings after a 
trading pause.
Proposed Amendments to Rule 1.1 (Definitions)
    To support DMMs and auctions on Pillar, the Exchange proposes to 
amend Rule 1.1 of the Pillar Platform Rules to include additional 
definitions.
    First, the Exchange proposes to define the terms ``Designated 
Market Maker,'' ``DMM,'' and ``DMM unit'' in proposed Rule 1.1. 
Specifically, the term ``DMM'' would mean an individual member, 
officer, partner, employee or associated person of a DMM unit who is 
approved by the Exchange to act in the capacity of a DMM. This proposed 
rule text is based on current Rule 2(i) without any differences. The 
term ``DMM unit'' would mean a member organization or unit within a 
member organization that has met the requirements of Rules 98 and 104. 
This proposed rule text is based on the first sentence of Rule 2(j) 
without any differences. The Exchange does not propose text based on 
the second sentence of Rule 2(j) because the Pillar Platform Rules do 
not use the term ``DMM organization'' or ``DMM member organization.''
    Second, the Exchange proposes to define the term ``Direct Listing'' 
to mean a security that is listed under Footnote (E) to Section 102.01B 
of the Listed Company Manual. This type of listing is currently 
referenced in Rule 15(c)(1)(D) and Rule 104(a)(2) in connection with 
obligations relating to the opening transaction for such listings. As 
discussed below, the Exchange proposes to move text relating to that 
type of listing from those rules to the Pillar Auction Rules and 
believes that it would promote clarity and transparency in Exchange 
rules to use a single defined term to reference this type of listing. 
The Exchange proposes to use the term ``Direct Listing'' as this is how 
this type of listing has been described publicly, and therefore is a 
familiar term to member organizations and the public.
    Third, the Exchange proposes to define the term ``Initial Public 
Offering'' or ``IPO'' as having the same meaning as that term is used 
in Section 12(f)(1)(G) of the Act. The term ``initial public offering'' 
is currently referenced in Rule 15(c)(1)(B) and the Exchange proposes 
to use this term in more than one place in the Pillar Auction Rules. 
The Exchange believes it would promote clarity and transparency to 
include this definition in Exchange rules. The Exchange further 
believes that the cross reference to Section 12(f)(1)(G) of the Act 
provides clarity of the scope of the term IPO as used in Exchange 
Pillar rules.
    Finally, the Exchange proposes to add the term ``Official Closing 
Price'' to Rule 1.1. Rule 123C(1)(e) currently defines the term 
``Official Closing Price.'' For Pillar, similar to NYSE Arca and NYSE 
American, the Exchange proposes to include that definition in Rule 1.1 
rather than the Pillar Auction Rules. The Exchange further proposes 
that the Exchange's proposed definition of Official Closing Price would 
be based on the NYSE Arca Rule 1.1 and NYSE American Rule 1.1E 
definitions of Official Closing Price rather than the Rule 123C(1)(e) 
definition of that term.
    The NYSE Arca definition has four substantive differences from the 
current NYSE Rule 123C(1)(e) definition (the NYSE American definition 
has three substantive differences from the current NYSE definition).
     First, the NYSE Arca definition provides for how the 
Official Closing Price is determined for a security listed on NYSE Arca 
that is a Derivative Securities Product, which is a defined term on 
NYSE Arca that has the same meaning as the term ``Exchange Traded 
Product'' under Exchange Rules, and that has not had a closing auction 
of one round lot or more on a trading day.\12\ Because the Exchange now 
has rules permitting listing of Exchange Traded Products,\13\ the 
Exchange proposes to include text based on NYSE Arca Rule 1.1(ll)(1)(B) 
in proposed Rule 1.1(s)(1)(B). With this proposed difference, for 
Exchange Traded Products that list on the Exchange, the Exchange would 
determine an Official Closing Price for such securities in the same 
manner as determined by NYSE Arca for such securities.
---------------------------------------------------------------------------

    \12\ See Rule 1.1(i) (defining the term ``Exchange Traded 
Product'' to mean a security that meets the definition of 
``derivative securities product'' in Rule 19b-4(e) under the Act).
    \13\ See Rules 5P and 8P.
---------------------------------------------------------------------------

     Second, under NYSE Arca Rule 1.1(ll)(1)(C) and NYSE 
American Rule 1.1E(gg)(2)(C), if NYSE Arca or NYSE American cannot 
determine the Official Closing Price under subparagraphs (A) or (B) of 
those Exchange's respective rules, the Official Closing Price will be 
the most recent consolidated last-sale eligible trade during Core 
Trading Hours on that trading day. By contrast, under NYSE Rule 
123C(1)(e)(i), if the Exchange does not have a closing transaction of a 
round lot or more, the Official Closing Price will be the most recent 
last-sale eligible trade in such security on the Exchange on that 
trading day. The Exchange proposes that on Pillar, the Exchange will 
follow the NYSE Arca and NYSE American manner of determining the 
Official Closing Price if there is no closing transaction of a round 
lot or more. As proposed, if there is not a closing auction of a round 
lot or more, the Official Closing Price would be the most recent 
consolidated last-sale eligible trade during Core Trading Hours on that 
trading day. The Exchange believes that this proposed substantive 
difference to Exchange rules will promote consistency in how an 
Official Closing Price is determined across affiliated exchanges, and 
is more likely to represent a recent valuation in a security if an 
exchange other than NYSE reports a last-sale eligible trade at a later 
time than the Exchange.
     Third, current Rule 7.31(a)(1)(B)(i) provides that the 
Exchange would use the Official Closing Price for purposes of 
determining Trading Collars for Market Orders. For UTP Securities, the 
official closing price as determined by the primary listing market is 
used as the Official Closing Price for this purpose. Proposed Rule 
1.1(s)(5) is based on NYSE Arca Rule 1.1(s)(5) and NYSE American Rule 
1.1(gg)(5) and would specify that the Exchange would use the official 
closing price of the primary listing market for purposes of Trading 
Collars for Market Orders under Rule 7.31(a)(1)(B)(i).
     Finally, NYSE Arca Rule 1.1(ll) and NYSE American Rule 
1.1(gg) provide that an Official Closing Price may be adjusted to 
reflect a corporate action or a correction to a closing price, as 
disseminated by the primary listing market for the security. Proposed 
Rule 1.1(s)(6) is based on these NYSE Arca and NYSE American rules and 
would specify that the Exchange would similarly adjust an Official 
Closing Price to reflect a corporate action in a security or a 
correction to a closing price.

[[Page 6871]]

    The Exchange also proposes non-substantive differences to Rule 1.1 
to re-number the existing definitions so that the above-described new 
definitions can be included in alphabetical order in Rule 1.1. The 
Exchange also proposes a non-substantive amendment to Rule 1.1(q) 
(proposed to be Rule 1.1(t)) to fix a typographical error to add a 
quotation mark after the term ``Best Offer'' in the last sentence of 
that definition.
Proposal To Add the DMM as a Participant Under Pillar Platform Rules
    As noted above, once Exchange-listed securities transition to 
Pillar, such securities will be subject to the Pillar Platform Rules, 
including Rules 7.36 (Order Ranking and Display) and 7.37 (Order 
Execution and Routing). Accordingly, orders in Exchange-listed 
securities will be eligible for Setter Priority, as described in Rule 
7.36(h) and will be allocated on parity, as provided for in Rule 
7.37(b).
    Because DMMs are not assigned to UTP Securities, Rules 7.36 and 
7.37 do not currently address the DMM participation in allocation. To 
support the transition of Exchange-listed securities to Pillar, the 
Exchange proposes to amend these rules to reflect that the DMM would be 
included in the allocation process for securities assigned to that DMM.
    First, the Exchange proposes to amend Rule 7.36(a)(5), which 
defines the term ``Participant,'' to add the DMM to this definition. 
The proposed new rule would provide that (new text underlined):
[GRAPHIC] [TIFF OMITTED] TN28FE19.000

    This proposed rule text is based in part on Rule 72(c)(ii), which 
provides that the DMM constitutes an individual participant for 
purposes of share allocation in a security that is assigned to such 
DMM.
    Next, the Exchange proposes to amend Rule 7.37(b)(7), which is 
currently designated as ``Reserved,'' to delete that term and add: 
``DMM Participant Allocation. An Allocation to the DMM Participant will 
be allocated to orders that comprise the DMM Participant by working 
time.'' With this proposed rule change, if a DMM Participant has more 
than one order at a price and receives an allocation, that parity 
allocation would be allocated among the DMM orders by working time 
associated with such orders. This proposed rule text is new for Pillar 
and uses Pillar terminology to provide transparency regarding how 
multiple orders from the DMM Participant would be allocated among those 
orders.
    At this time, the Exchange is not proposing to move other rules 
governing DMMs to the Pillar Platform Rules, such as Rules 98 
(Operation of a DMM Unit), 103 (Registration and Capital Requirements 
of DMMs and DMM Units), 103B (Security Allocation and Reallocation), 
and 104 (Dealings and Responsibilities of DMMs). Accordingly, these 
current rules, and any other current rule that does not include a 
preamble that such rule is not applicable to trading on the Pillar 
trading platform, will continue to be applicable to DMMs once Exchange-
listed securities transition to the Pillar trading platform.
Proposed Amendments to Rule 7.31 (Orders and Modifiers)
    Rule 7.31 sets forth the orders and modifiers that are available 
for trading on Pillar on the Exchange. Because the Exchange currently 
trades only UTP Securities, this rule does not address order types that 
would participate in an auction on the Exchange. For example, Rule 
7.31(c) defines Auction-Only Orders, but that rule currently provides 
that these orders are only to be routed. The Exchange proposes to amend 
Rule 7.31 to: (1) Provide that Auction-Only Orders would be available 
for auctions on the Exchange for Exchange-listed securities; (2) add 
additional Auction-Only Orders that are based on functionality 
currently available under Rules 13 and 70.25; and (3) specify which 
existing orders and modifiers would not be eligible to participate in 
an auction.
    Auction-Only Orders for Auction-Eligible Securities.\14\ Under 
current Rule 7.31(c), which defines Auction-Only Orders, if the 
Exchange receives an Auction-Only Order in a UTP Security, the Exchange 
routes such order directly to the primary listing market for that 
security. Therefore, Rule 7.31(c) currently describes an Auction-Only 
Order as a Limit Order or Market Order that is only to be routed 
pursuant to Rule 7.34.
---------------------------------------------------------------------------

    \14\ See discussion infra regarding proposed Rule 7.35(a) and 
definitions for purposes of Auctions, including the terms ``Core 
Open Auction,'' ``Trading Halt Auction,'' ``Closing Auction,'' and 
``Auction-Eligible Securities.''
---------------------------------------------------------------------------

    The Exchange proposes to amend Rule 7.31(c) to reflect the 
difference between Auction-Only Orders for Exchange-listed securities, 
which will be auction eligible when they transition to Pillar, and 
Auction-Only Orders for UTP Securities, which are routed to the primary 
listing market. As proposed, Rule 7.31(c) would provide that an 
Auction-Only Order is a Limit Order or Market Order that is to be 
traded only in an auction pursuant to the Rule 7.35 Series (for 
Auction-Eligible Securities) \15\ or routed pursuant to Rule 7.34 (for 
UTP Securities). This proposed rule text is based on NYSE Arca Rule 
7.31-E(c) and NYSE American Rule 7.31E(c) with a non-substantive, 
clarifying difference to specify that such orders in Auction-Eligible 
Securities would be traded in an auction pursuant to the Rule 7.35 
Series and that such orders in UTP Securities would be routed pursuant 
to Rule 7.34.
---------------------------------------------------------------------------

    \15\ See discussion infra regarding the proposed Rule 7.35 
Series.
---------------------------------------------------------------------------

    This proposed amendment would also add to the definition of 
Auction-Only Orders additional order types that are designated for an 
auction and that are currently available for Exchange-listed 
securities. First, because d-Quotes currently can be designated to 
exercise discretion only in auctions, the Exchange proposes to include 
in the definition of Auction-Only Orders how

[[Page 6872]]

discretionary instructions would function on Pillar auctions.\16\ 
Second, the Exchange proposes to add the Closing Imbalance Offset Order 
to the Pillar rules. The Exchange also proposes non-substantive 
differences to distinguish Auction-Only Orders that would participate 
in the Core Open and Trading Halt Auctions from Auction-Only Orders 
that would participate in the Closing Auction.\17\
---------------------------------------------------------------------------

    \16\ See Rule 70.25(a)(ii).
    \17\ As described below, the Exchange proposes to define the 
terms Core Open Auction, Trading Halt Auction, and Closing Auction 
in proposed Rule 7.35(a).
---------------------------------------------------------------------------

    Core Open and Trading Halt Auctions. Proposed Rule 7.31(c)(1) would 
describe the Auction-Only Orders designated for an opening or reopening 
auction that the Exchange would accept before the Core Trading Session 
begins (for the Core Open Auction) or during a halt or pause (for a 
Trading Halt Auction). As proposed, any quantity of such orders that 
are not traded in the designated auction would be cancelled. This 
proposed text does not introduce new functionality, but uses Pillar 
terminology relating to auctions. The Exchange proposes to move the 
definitions for a Limit-on-Open Order (``LOO Order'') and a Market-on-
Open Order (``MOO Order'') as subparagraphs under Rule 7.31(c)(1) 
without any changes.\18\
---------------------------------------------------------------------------

    \18\ Current Rule 7.31(c)(1) relating to LOO Orders would be 
renumbered as Rule 7.31(c)(1)(A) and current Rule 7.31(c)(2) 
relating to MOO Orders would be renumbered as Rule 7.31(c)(1)(B).
---------------------------------------------------------------------------

    Currently, under Rule 70.25(a)(ii), a d-Quote can include an 
instruction to participate in the opening transaction only, meaning 
that the discretionary instructions for an e-Quote would be live for 
the opening transaction only.\19\ The Exchange proposes to replicate 
this d-Quote behavior on Pillar without any substantive differences and 
proposes to describe it as an Auction-Only Order that would be called 
the ``Opening D Order.''
---------------------------------------------------------------------------

    \19\ The Exchange has filed a separate proposed rule change to 
establish D Orders on the Pillar trading platform, which are based 
on d-Quotes under Rule 70.25. See Securities Exchange Act Release 
No. 84806 (December 12, 2018), 83 FR 64913 (December 18, 2018) (SR-
NYSE-2018-52) (Notice of filing).
---------------------------------------------------------------------------

    Proposed Rule 7.31(c)(1)(C) would provide that an Opening D Order 
is a Limit Order to buy (sell) with an instruction to exercise 
discretion in the Core Open Auction or Trading Halt Auction up (down) 
to a designated undisplayed price. Just as d-Quotes are available only 
to Floor brokers, proposed Rule 7.31(c)(1)(C)(i) would provide that an 
Opening D Order may be entered by a Floor broker only. Because an 
Opening D Order would cancel if it does not trade in the designated 
auction, this order type would not be eligible to trade in continuous 
trading. This proposed rule text is based on current functionality 
without any substantive differences, but uses Pillar terminology.
    Because an Opening D Order could be entered for a UTP Security, 
proposed Rule 7.31(c)(1)(C)(ii) would provide that based on the 
instruction of the Floor broker, an Opening D Order in a UTP Security 
would be routed to the primary listing market as either a MOO or a LOO 
Order. This is consistent with the treatment of Auction-Only Orders 
today in UTP securities, which are routed to the primary listing market 
for that security.
    Closing Auctions. Proposed Rule 7.31(c)(2) would describe the 
Auction-Only Orders designated for a closing auction and proposes that 
the Exchange would begin accepting such Auction-Only Orders when it 
begins accepting orders for a trading day as provided for in Rule 
7.34(a)(1).\20\ The Exchange proposes to move the definitions for a 
Limit-on-Close Order (``LOC Order'') and a Market-on-Close Order (``MOC 
Order'') as subparagraphs under Rule 7.31(c)(2) without any 
changes.\21\
---------------------------------------------------------------------------

    \20\ Rule 7.34(a)(1) provides that the Exchange will begin 
accepting orders 30 minutes before the Early Trading Sessions begins 
at 7:00 a.m.
    \21\ Current Rule 7.31(c)(3) relating to LOC Orders would be 
renumbered as Rule 7.31(c)(2)(A) and current Rule 7.31(c)(4) 
relating to MOO Orders would be renumbered as Rule 7.31(c)(2)(B).
---------------------------------------------------------------------------

    Similar to d-Quotes for opening transactions, Rule 70.25(a)(ii) 
provides that a d-Quote can include an instruction to participate in 
the closing transaction only, meaning that the discretionary 
instructions for an e-Quote would be live only for an auction. Because 
the discretionary instructions are live only for an auction, the 
Exchange proposes to describe this functionality for Pillar as part of 
Auction-Only Orders. As proposed, a Closing D Order would be defined in 
Rule 7.31(c)(2)(C) as a Limit Order to buy (sell) with an instruction 
to exercise discretion in the Closing Auction up (down) to a designated 
undisplayed price. As with d-Quotes, proposed Rule 7.31(c)(2)(C)(i) 
would provide that a Closing D Order may be entered by a Floor broker 
only.
    Proposed Rule 7.31(c)(2)(C)(ii) would provide that, on arrival, a 
Closing D Order would be processed as a Limit Order and may trade or 
route prior to the Closing Auction. This proposed rule text is based on 
how a d-Quote with instructions to participate in the closing 
transaction only currently operate, as such d-Quotes are eligible to 
trade during continuous trading prior to the closing transaction as a 
straight e-Quote and the discretionary instructions of such a d-Quote 
are active only for an auction.
    Proposed Rule 7.31(c)(2)(C)(iii) would provide that based on the 
instruction of the Floor broker, a Closing D Order in a UTP Security 
would be routed to the primary listing market as either a MOC or LOC 
Order. This is consistent with the treatment of Auction-Only Orders 
today in UTP securities, which are routed to the primary listing market 
for that security.
    To complete the list of Auction-Only Orders that would be available 
on the Exchange when it introduces auctions on Pillar for Exchange-
listed securities, the Exchange proposes to amend Rule 7.31(c) to 
include the proposed Closing Imbalance Offset Order (``Closing IO 
Order''), which is based on the Closing Offset Order (``CO Order'') 
currently available for Exchange-listed securities.\22\ Proposed Rule 
7.31(c)(2)(D) would provide that a Closing IO Order is a Limit Order to 
buy (sell) in an Auction-Eligible Security that is to be traded only in 
a Closing Auction.
---------------------------------------------------------------------------

    \22\ See Rule 13(c)(1).
---------------------------------------------------------------------------

    Proposed Rule 7.31(c)(2)(D)(i) would further provide that a Closing 
IO Order would participate in a Closing Auction only if: (i) There is 
an Unpaired Quantity (a term that will be defined in proposed Rule 
7.35(a), described below) in the security on the opposite side of the 
market from the Closing IO Order after taking into account all other 
orders eligible to trade at the auction price; and (ii) the limit price 
of the Closing IO Order to buy (sell) is at or above (below) the price 
of the Closing Auction. This text is based on Rule 13(c)(1)(i) and 
(ii), which describe when a CO Order may participate in the Closing 
Auction, with changes to reflect Pillar terminology.
    Proposed Rule 7.31(c)(2)(D)(ii) would provide that the working 
price of a Closing IO Order to buy (sell) would be adjusted to be equal 
to the price of the Closing Auction, provided that the working price of 
the Closing IO Order would not be higher (lower) than its limit price. 
This proposed text would add further specificity to the operation of 
Closing IO Order and is based on Rule 13(c)(1)(iii) which provides that 
a CO Order will participate in the Closing Auction if its limit price 
is at or within the price of the Closing Auction. The Exchange proposes 
to specify the ranking and allocation of the proposed Closing IO Orders 
in proposed Rule 7.35B, described below.

[[Page 6873]]

    Orders Not Eligible to Participate in an Auction. The Exchange 
proposes that unless otherwise specified, orders and modifiers 
described in Rule 7.31 would be eligible to participate in an Auction. 
The Exchange proposes that the following order types would not be 
eligible to participate in an Auction:
     Rule 7.31(b)(2) would be amended to provide that a Limit 
Order designated IOC would not be eligible to participate in any 
Auctions. This proposed rule is based on NYSE Arca Rule 7.31-E(b)(2) 
and NYSE American Rule 7.31E(b)(2) with a non-substantive difference to 
capitalize the term ``Auctions,'' which is a defined term described 
below in proposed Rule 7.35(a)(1). This proposed rule change would be a 
substantive difference on the Exchange, as currently, specified orders 
designated IOC are eligible to participate in an opening or reopening 
auction.\23\ The Exchange believes that the proposed Pillar rule would 
standardize the treatment of Limit IOC Orders across affiliated 
exchanges. In addition, the Exchange believes that cancelling such 
orders on arrival rather than holding them for an auction is consistent 
with the instruction of such orders to cancel if not immediately 
executable.
---------------------------------------------------------------------------

    \23\ See Rule 13(b)(2)(D) and (E) (specifying which IOC orders 
entered before the Exchange opening or during a trading halt will be 
held for the opening or reopening, respectively).
---------------------------------------------------------------------------

     Rule 7.31(d)(2) would be amended to provide that Non-
Displayed Limit Orders would not participate in any Auctions. This 
proposed rule is based on NYSE Arca Rule 7.31-E(d)(2) and NYSE American 
Rule 7.31E(d)(2) with a non-substantive difference to capitalize the 
term Auctions. This proposed rule is also consistent with Rule 
13(d)(2)(D), which provides that Non-Displayed Reserve Orders shall not 
participate in manual executions, which means that they are not 
eligible to participate in any auctions under current rules.
     Rule 7.31(d)(3) would be amended to provide that Mid-Point 
Liquidity Orders (``MPL Order'') would not participate in any Auctions. 
This proposed rule is based on NYSE Arca Rule 7.31-E(d)(3) and NYSE 
American Rule 7.31E(d)(3) with a non-substantive difference to 
capitalize the term Auctions. This proposed rule text is also based in 
part on Rule 13(d)(1)(A), which provides that MPL Orders are not 
eligible for openings, reopenings, or closing transactions.
     Rule 7.31(e)(2)(A) would be amended to provide that ALO 
Orders may participate in Auctions, but the ALO designation would be 
ignored and that an ALO Order that has not traded in an Auction would 
be assigned a working price and display price pursuant to Rule 
7.31(e)(2)(B). This proposed rule is based on NYSE Arca Rule 7.31-
E(e)(2)(A) with a non-substantive difference to capitalize the term 
Auction. This proposed rule text is also based in part on Rule 
13(e)(1)(A), which provides that an order designated ALO may 
participate in openings, reopenings, or closings, but the ALO 
designation shall be ignored.
     Rule 7.31(h)(4) would be amended to provide that Non-
Displayed Primary Pegged Orders would not participate in any Auctions. 
This proposed rule is based on NYSE American Rule 7.31E(h) with a non-
substantive difference that on the Exchange, this text would be 
specific to Non-Displayed Primary Pegged Orders, which is the only type 
of non-displayed Pegged Order available on the Exchange. This proposed 
rule is also based in part on how pegging interest currently functions 
on the Exchange. Currently, because pegging interest is an e-Quote, it 
may be designated as a Non-Display Reserve e-Quote pursuant to Rule 
70(b)(ii) and (f)(ii). In such case, this non-displayed pegging 
interest would not participate in openings, re-openings, or closings. 
Accordingly, this proposed rule text is based on current functionality.
     Rule 7.31(i)(2) would be amended to provide that orders 
marked with a Self-Trade Prevention (``STP'') modifier would not be 
prevented from interacting during any Auction. This proposed rule is 
based on the last sentence of NYSE Arca Rule 7.31-E(i)(2) and the last 
sentence of NYSE American Rule 7.31E(i)(2) with a non-substantive 
difference to capitalize the term Auction. This proposed rule text is 
also based on the fourth paragraph of Rule 13(f)(3)(B), which provides 
that STP modifiers will not be active and will be ignored for opening, 
re-opening, and closing transactions.
    The Exchange proposes two additional changes to Rule 7.31. First, 
the Exchange proposes to amend Rule 7.31(a)(2)(B), relating to Limit 
Order Price Protection. Currently, the rule provides that a Limit Order 
entered before the Core Trading Session that becomes eligible to trade 
in the Core Trading Session will become subject to Limit Order Price 
Protection when the Core Trading Session begins. With this 
functionality, orders not yet eligible to trade are not rejected on 
arrival, but rather are evaluated for Limit Order Price Protection when 
they become eligible to trade. The Exchange proposes to amend this 
existing rule text to specify that it would be applicable to UTP 
Securities only.
    Because an order in an Auction-Eligible Security would be subject 
to an auction process when it becomes eligible to trade, the Exchange 
proposes different treatment for such securities. In that auction 
process, a Limit Order priced better than the Auction Price would be 
guaranteed to participate in the applicable Auction.\24\ If a security 
opens or reopens on a quote, it is because the Exchange has not 
received orders that can trade. Accordingly, the Exchange does not 
believe that orders in Auction-Eligible Securities would need to be 
subject to Limit Order Price Protection when they become eligible to 
trade. Accordingly, the Exchange proposes to amend Rule 7.31(a)(2)(B) 
to add that a Limit Order in an Auction-Eligible Security entered 
before the Core Trading Session or during a trading halt or pause 
(i.e., periods when the Exchange is not open for trading in such 
securities), would not be subject to Limit Order Price Protection.
---------------------------------------------------------------------------

    \24\ See discussion infra regarding proposed Rule 7.35A(h) 
regarding allocation of orders in an Auction.
---------------------------------------------------------------------------

    Second, the Exchange proposes to amend Rule 7.31(h)(2) to provide 
that a Primary Pegged Order would not be eligible to participate in the 
Closing Auction. The Exchange believes that excluding Primary Pegged 
Orders from participating in the Closing Auction would streamline order 
processing in the Closing Auction. As described below, orders would 
participate in the Closing Auction at their limit price, which would 
likely be a different price from where a Primary Pegged Order is 
displayed immediately prior to the Closing Auction. Because a Primary 
Pegged Order, which intraday is pegged to display to the same-side 
PBBO, would likely need to be repriced to its limit price in order to 
participate in the Closing Auction, the Exchange believes that making 
such orders ineligible to participate in the Closing Auction would 
streamline order processing when transitioning to the Closing Auction.
Proposed Rule 7.35 (General)
    Because there would be multiple rules governing auctions that each 
reference Rule ``7.35,'' the Exchange proposes to add a sub-heading 
above current Rule 7.35 that states ``Rule 7.35 Series. Auctions.'' The 
Exchange then proposes to amend the heading for Rule 7.35 to delete the 
term ``Reserved'' and rename it ``General.''
    Proposed Rule 7.35 would set forth the general rules for auctions 
on the Exchange. As proposed, Rule 7.35

[[Page 6874]]

would be applicable to all auctions on the Exchange.
    Definitions. Proposed Rule 7.35(a) would set forth definitions that 
would be used for purposes of Rule 7P. The Exchange proposes to set 
forth the definitions in alphabetical order in the rule text, but will 
describe them out of alphabetical order in this filing to provide 
context for definitions that reference other definitions.
    Proposed Rule 7.35(a)(1) would provide that the term ``Auction'' 
would refer to the process for opening, re-opening, or closing of 
trading of Auction-Eligible Securities on the Exchange, which could 
result in either a trade or a quote. The Current Auction Rules use 
varying terms, including referencing an opening, re-opening, or closing 
``transaction.'' For Pillar, the Exchange proposes that the term 
``Auction'' would mean any action that results in the opening, 
reopening, or closing of trading, which could result in a trade or a 
quote, or in the case of the close of trading, no action.\25\ For 
specific Auctions, the Exchange proposes to use terms based on NYSE 
Arca Rule 7.35-E and NYSE American 7.35E:
---------------------------------------------------------------------------

    \25\ Currently, if there is no interest for a closing 
transaction, the DMM is not required to take any action on such 
security. Because the Exchange does not have any trading after 4:00 
p.m., the Exchange does not publish a quote for such security if 
there is no closing transaction. The Exchange will disseminate an 
Official Closing Price for such security that is determined based on 
Rule 123C(1)(e)(i)-(iii), or on Pillar, under proposed Rule 1.1(s).
---------------------------------------------------------------------------

     Proposed Rule 7.35(a)(1)(A) would provide that ``Core Open 
Auction'' means the Auction that opens trading at the beginning of the 
Core Trading Session.\26\ This proposed term would replace use of the 
terms ``opening'' and ``opening transaction'' as used in the Current 
Auction Rules.
---------------------------------------------------------------------------

    \26\ As described below, the Exchange proposes to amend Rule 
7.34(a)(2) relating to the Core Trading Session. The term ``Core 
Trading Hours'' means ``the hours of 9:30 a.m. Eastern Time through 
4:00 p.m. Eastern Time or such other hours as may be determined by 
the Exchange from time to time.'' See Rule 1.1.
---------------------------------------------------------------------------

     Proposed Rule 7.35(a)(1)(B) would provide that ``Trading 
Halt Auction'' means the Auction that reopens trading following a 
trading halt or pause. This proposed term would replace use of the 
terms ``reopening'' or ``reopening transaction'' as used in the Current 
Auction Rules.
     Proposed Rule 7.35(a)(1)(C) would provide that ``Closing 
Auction'' means the Auction that closes trading at the end of the Core 
Trading Session. This proposed term would replace use of the terms 
``close,'' ``closing,'' and ``closing transaction'' as used in the 
Current Auction Rules.
     Proposed Rule 7.35(a)(1)(D) would provide that ``IPO 
Auction'' means the Core Open Auction for the first day of trading on 
the Exchange of a security that is an IPO. This definition would be new 
for Pillar and is based on references to IPOs in the Current Auction 
Rules.
     Proposed Rule 7.35(a)(1)(E) would provide that ``Direct 
Listing Auction'' means the Core Open Auction for the first day of 
trading on the Exchange of a security that is a Direct Listing. This 
definition would be new for Pillar and is based on the Exchange's 
listing rules that provide for a Direct Listing, as described above.
    Proposed Rule 7.35(a)(2) would provide that the term ``Auction-
Eligible Security'' would mean all securities for which the Exchange is 
the primary listing market. This proposed definition is based on NYSE 
American Rule 7.35E(a)(1), which also defines the term ``Auction-
Eligible Security.'' Because the Exchange does not conduct Auctions in 
UTP Securities, the Exchange proposes that this definition would be 
applicable to Exchange-listed securities only.
    Proposed Rule 7.35(a)(3) would provide that the term ``Auction 
Imbalance Freeze'' means the period that begins before the scheduled 
time for an Auction. This proposed definition is based in part on NYSE 
Arca Rule 7.35-E(a)(3) and NYSE American Rule 7.35E(a)(3). Because, as 
described below, there will be an Auction Imbalance Freeze for the 
Closing Auction only, the Exchange will set forth the details regarding 
such freeze in proposed Rule 7.35B.
    Proposed Rule 7.35(a)(4) would provide that the term ``Auction 
Imbalance Information'' means the information that is disseminated by 
the Exchange for an Auction. This proposed definition is based in part 
on NYSE Arca Rule 7.35-E(a)(4) and NYSE American Rule 7.35E(a)(4), 
which also use this term. While the Exchange proposes to use the same 
term as NYSE Arca and NYSE American, the content of the Auction 
Imbalance Information that would be disseminated by the Exchange would 
not be based on NYSE Arca or NYSE American Pillar rules. Instead, the 
Exchange proposes to continue disseminating the same content for its 
Auction Imbalance Information as under the Current Auction Rules, which 
is described in Rule 15(g) as ``Opening Order Imbalance Information,'' 
in Rule 123C(5) as ``Publication of Mandatory MOC/LOC and Information 
Imbalances,'' and in Rule 123C(6) as ``Order Imbalance Information Data 
Feed.'' In the Pillar Auction Rules, the Exchange proposes to use 
standardized Pillar terminology, as defined below, to describe such 
information.
    The following are proposed defined terms that are used for Auction 
Imbalance Information under the Pillar Auction Rules:
     Proposed Rule 7.35(a)(5) would define the term ``Auction 
Price'' as the price at which an Auction is conducted. This would be a 
new term in the Pillar Auction Rules and is based in part on the use of 
the term ``opening or reopening price'' in Rule 115A(a)(1) and use of 
the term ``closing price'' in Rule 123C(7).
    [cir] Proposed Rule 7.35(a)(5)(A) would provide that a buy (sell) 
order is ``better-priced'' if it is priced higher (lower) than the 
Imbalance Reference Price or the Auction Price. This proposed 
definition is based in part on the term ``Better Priced'' as defined in 
Rule 123C(1)(a) relating to the close.\27\ In the Pillar Auction Rules, 
the Exchange proposes to use the term ``better-priced'' for all 
Auctions.\28\ The rule would further provide that Market, MOO, and MOC 
Orders would be better-priced orders unless such orders have been 
ranked as a Priority 2--Display Order during a Short Sale Period as 
provided for in Rule 7.16(f). This proposed rule text is based in part 
on Rule 115A(a)(1)(A), which provides that Market Orders and MOO Orders 
are guaranteed to participate in an opening or reopening transaction, 
and Rule 123C(7)(a), which provides that MOC Orders are guaranteed to 
participate in the closing transaction. Finally, this definition would 
provide that DMM Interest (defined below) to buy (sell) would never be 
a better-priced order, even if priced higher (lower) than the Imbalance 
Reference Price or Auction Price. This proposal is consistent with the 
Exchange's proposal, described in greater detail below, that DMM 
Interest is not guaranteed to participate in an Auction.\29\
---------------------------------------------------------------------------

    \27\ Rule 123C(1)(a) provides that ``[b]etter priced than the 
closing price means an order that is lower than the closing price in 
the case of an order to sell or higher than the closing price in the 
case of an order to buy.'' In addition, for opening and reopening 
transactions, Rule 115A(a)(1)(A) describes interest to buy (sell) 
priced higher (lower) than the opening or reopening price, which is 
the same definition as the proposed ``better-priced'' orders in the 
Pillar Auction Rules.
    \28\ As described in greater detail below, better-priced orders 
are guaranteed to participate in an Auction. See discussion infra 
regarding proposed Rules 7.35A(h)(1) and 7.35B(h)(1).
    \29\ See discussion infra regarding proposed Rules 7.35A(h)(2) 
and (3) and 7.35B(h)(2) and (3).
---------------------------------------------------------------------------

    [cir] Proposed Rule 7.35(a)(5)(B) would provide that a buy (sell) 
order is ``at-priced'' if it is priced equal to the Imbalance Reference 
Price or Auction

[[Page 6875]]

Price. This would be a new term for the Pillar Auction Rules and is 
based in part on use of the phrase orders ``with a price equal to the 
closing price,'' as used in Rule 123C(7)(b), or orders ``priced equal 
to the opening or reopening price of a security,'' as used in Rule 
115A(a)(1)(B).
     In proposed Rule 7.35(a)(8), the Exchange proposes to 
define ``DMM Interest'' as all buy and sell interest entered by a DMM 
unit in its assigned securities. As noted above, pursuant to Rule 
104(a)(2) and (3), the DMM has an obligation to facilitate Auctions in 
assigned securities and to supply liquidity as needed. In addition, 
pursuant to Rule 104(f)(ii), the DMM has the obligation to maintain a 
fair and orderly market in the stocks assigned to the DMM, which 
implies the maintenance of price continuity with reasonable depth, and 
to minimize the effects of temporary disparity between supply and 
demand. The Exchange currently makes functionality available to DMMs to 
facilitate these obligations when they conduct Auctions. For example, 
when facilitating an auction, a DMM can either manually enter buy or 
sell interest into the graphical user interface that is used by the DMM 
on the Trading Floor \30\ to manage the auction process or 
algorithmically enter buy or sell interest in response to the 
Exchange's electronic request to the DMM unit to conduct an 
Auction.\31\ Currently, the DMM interest entered as part of this 
functionality can be intended to participate in an Auction only or to 
meet the obligation to maintain price continuity and depth in assigned 
securities immediately following the auction. In the Pillar Auction 
Rules, the Exchange believes it would promote transparency regarding 
the auction process to separately define these types of DMM Interest 
for Auctions. As described below, these terms would be used in the 
Pillar Auction Rules relating to Auction Imbalance Information, entry 
of orders during the Auction Processing Period, the opening and closing 
process, and auction allocation. As proposed, the following types of 
DMM Interest would be available to DMMs to facilitate their obligations 
under Rule 104 in their assigned securities:
---------------------------------------------------------------------------

    \30\ The term ``Trading Floor'' is defined in Rule 6A to mean 
the restricted-access physical areas designated by the Exchange for 
the trading of securities, commonly known as the ``Main Room'' and 
the ``Buttonwood Room.''
    \31\ Pursuant to Rule 104(b)(i), DMM units have the ability to 
employ algorithms for quoting and trading consistent with NYSE and 
SEC regulations, and as provided for in Rules 104(a)(2) and (3) and 
104(b)(ii), such algorithms will have access to aggregate order 
information in order to comply with the DMM requirement to 
facilitate Auctions.
---------------------------------------------------------------------------

    [cir] Proposed Rule 7.35(a)(8)(A) would define ``DMM Auction 
Liquidity'' as non-displayed buy and sell interest that is (i) entered 
by a DMM either manually on the Trading Floor or as part of the DMM 
unit's electronic message to conduct an Auction; (ii) designated for an 
Auction only; and (iii) not entered as an order or modifier as defined 
in Rule 7.31. This would be a new term for Pillar Auction Rules that 
would describe current DMM functionality to enter buy and sell interest 
intended for an auction only. Currently, such DMM interest is not 
displayed, is generally entered by the DMM unit contemporaneously with 
conducting an Auction, and cancels if it does not participate in an 
Auction. In addition, this buy and sell interest is unique to the DMM's 
role in facilitating Auctions and differs from the type of orders 
defined in Rule 7.31. The term ``DMM Auction Liquidity'' would 
therefore not represent new functionality, but would define this 
functionality for the Pillar Auction Rules. Although it is not 
displayed, the Exchange proposes that for the purpose of ranking and 
allocation in an Auction, DMM Auction Liquidity would be ranked 
Priority 2--Display Orders. As described in greater detail below in 
connection with proposed Rule 7.35A(h)(3) and 7.35B(h)(3), this ranking 
would be applicable only for parity allocations among at-priced orders 
at the Auction Price and if the only DMM Interest is DMM Auction 
Liquidity, such DMM Interest would not have time priority on the 
allocation wheel. Proposed Rule 7.35(a)(4), which defines the term 
``Auction Imbalance Information,'' would further provide that DMM 
Auction Liquidity would never be included in Auction Imbalance 
Information. Because DMM Auction Liquidity generally is not entered 
until just before an Auction is to be conducted, is intended to be 
offsetting interest, is not displayed, and cancels if not executed in 
an Auction, the Exchange does not believe that this information should 
be included in Auction Imbalance Information.
    [cir] Proposed Rule 7.35(a)(8)(B) would define ``DMM Orders'' to be 
orders, as defined under Rule 7.31, entered by a DMM unit. Such orders 
would be ranked as provided for in Rule 7.31. Unlike DMM Auction 
Liquidity, DMM Orders would function no differently than the orders 
available to all other member organizations as described in Rule 7.31. 
For example, for the Closing Auction, this definition would include 
those orders entered by the DMM during continuous trading and that are 
not executed before the Closing Auction. As currently available, in 
Pillar, the DMM would also be able to enter DMM Orders when it uses its 
electronic functionality to facilitate an Auction.
    [cir] Proposed Rule 7.35(a)(8)(C) would define ``DMM After-Auction 
Orders'' to be orders, as defined under Rule 7.31, entered by a DMM 
unit before either the Core Open or Trading Halt Auction that would not 
participate in an Auction and would instead be intended to maintain 
price continuity with reasonable depth immediately following an 
Auction, as required by Rule 104(f)(ii). This proposed definition would 
be new for the Pillar Auction Rules and would describe the existing 
functionality, described above, that the DMM can enter buy and sell 
orders that are intended to be included in the Exchange Book 
immediately after the opening or reopening transaction to meet the 
obligation to maintain price continuity with reasonable depth following 
such transactions. The Exchange believes that this unique DMM 
obligation, and related functionality to meet this obligation, protects 
investors and the public interest by ensuring a smooth transition from 
an Auction to continuous trading. As further proposed, once entered on 
the Exchange Book, DMM After-Auction Orders would be ranked as provided 
for in Rule 7.31.
     Proposed Rule 7.35(a)(10) would define the term 
``Imbalance Reference Price'' as the reference price that is used for 
the applicable Auction to determine the Auction Imbalance Information. 
This would be a new term in the Pillar Auction Rules and is based on 
the use of the term ``reference price'' in Rules 123C(6)(a)(iii) and 
15(g)(2)(A).
    Proposed Rule 7.35(a)(4)(A) would define the term ``Imbalance'' to 
mean the volume of better-priced buy (sell) shares that cannot be 
paired with both at-priced and better-priced sell (buy) shares at the 
Imbalance Reference Price. Use of the term ``Imbalance'' in the Pillar 
Auction Rules refers to the manner by which an imbalance is calculated, 
and not the actual information that is disseminated. Under the Current 
Auction Rules, the Exchange calculates imbalance information in this 
manner.\32\ For

[[Page 6876]]

example, Rule 123C(4)(a)(iii) and (iv) provide that buy/sell closing 
volume does not include at-priced interest. The Exchange proposes to 
standardize this method of calculation for all Auctions with the 
proposed term ``Imbalance.'' As further proposed, the side that cannot 
be paired would be referred to as the ``Side of the Imbalance.''
---------------------------------------------------------------------------

    \32\ The Exchange currently calculates information relating to 
imbalances for its auctions differently from NYSE Arca and NYSE 
American. See, e.g., NYSE Arca Rule 7.35-E(a)(7) and NYSE American 
Rule 7.35E(a)(7) (describing the imbalance as the ``number of buy 
(sell) shares that cannot be matched with sell (buy) shares''). As 
described below, better-priced interest is guaranteed to participate 
in an Auction on the Exchange, therefore, the Exchange's manner of 
calculating the Imbalance provides information about how many shares 
would need to be satisfied in an Auction.
---------------------------------------------------------------------------

    The Exchange proposes that it would disseminate two types of 
Imbalance publications: Total Imbalance and Closing Imbalance. Total 
Imbalance information would be disseminated for all Auctions, and 
Closing Imbalance information would be disseminated for the Closing 
Auction only:
     Proposed Rule 7.35(a)(4)(A)(i) would provide that the term 
``Total Imbalance'' means for the Core Open and Trading Halt Auctions, 
the Imbalance of all orders eligible to participate in an Auction and 
for the Closing Auction, the Imbalance of MOC, LOC, and Closing IO 
Orders, and beginning five minutes before the scheduled end of Core 
Trading Hours, Closing D Orders.
    This would be a new term for the Pillar Auction Rules and is based 
in part on the term ``Total Imbalance,'' as used in NYSE Arca Rule 
7.35-E(a)(7)(A) and NYSE American Rule 7.35E(a)(7)(A), but with the 
substantive difference compared to those exchanges in how such 
Imbalance information would be calculated on the Exchange, as described 
above.
    For the Core Open and Trading Halt Auctions, this proposed rule 
text is based in part on Rule 15(g)(1), which provides that Order 
Imbalance Information includes real-time order imbalances that 
accumulate prior to the opening transaction on the Exchange and that 
such Order Imbalance Information includes all interest eligible for 
execution in the opening transaction of the security in Exchange 
systems. For the Closing Auction, this proposed rule text is based in 
part on Rules 123C(4) and (6)(a)(ii), with non-substantive differences 
to use Pillar terminology. Accordingly, the content included in Auction 
Imbalance Information under the Pillar Auction Rules would be the same 
as the content included in Order Imbalance Information under the 
Current Auction Rules, including that Total Imbalance information would 
differ for the Closing Auction as compared to the Total Imbalance 
information included for the Core Open or Trading Halt Auction.
     Proposed Rule 7.35(a)(4)(A)(ii) would provide that the 
term ``Closing Imbalance'' means the Imbalance of MOC and LOC Orders to 
buy and MOC and LOC Orders to sell. The rule would further provide that 
a ``Manual Closing Imbalance'' would mean a Closing Imbalance 
disseminated by the DMM before the Closing Auction Imbalance Freeze 
Time and a ``Regulatory Closing Imbalance'' would mean a Closing 
Imbalance disseminated at or after the Closing Auction Imbalance Freeze 
Time. These would be new terms for the Pillar Auction Rules to define 
the content currently described in Rule 123C as the ``Information 
Imbalance Publication'' and ``Mandatory MOC/LOC Imbalance 
Publication.'' As described in Rules 123C(1)(b) (defining the term 
``Informational Imbalance Publication'') and 123C(1)(d) (defining the 
term ``Mandatory MOC/LOC Imbalance Publication''), under the Current 
Auction Rules, this is the information that indicates a disparity 
between MOC and marketable LOC interest to buy and MOC and marketable 
LOC interest to sell.\33\ As described in Rule 123C(4), the manner by 
which the Informational Imbalance Publication and the Mandatory MOC/LOC 
Imbalance Publication is determined is the same; the difference between 
the two is when they are published and the impact they have on order 
entry. As discussed in greater detail below in connection with proposed 
Rule 7.35B(d), the Exchange proposes the same timing distinction 
between a Manual Closing Imbalance and a Regulatory Closing Imbalance.
---------------------------------------------------------------------------

    \33\ The Rule 123C(1)(d) definition provides further details of 
what constitutes a Mandatory MOC/LOC Imbalance Publication and the 
Exchange proposes to move that text in the Pillar Auction Rules to 
proposed Rule 7.35B(d)(1).
---------------------------------------------------------------------------

    Proposed Rule 7.35(a)(4)(B) would provide that the term ``Paired 
Quantity'' means the volume of better-priced and at-priced buy shares 
that can be paired with better-priced and at-priced sell shares at the 
Imbalance Reference Price and ``Unpaired Quantity'' means the volume of 
better-priced and at-priced buy shares that cannot be paired with both 
at-priced and better-priced sell shares at the Imbalance Reference 
Price. The proposed rule would further provide that the term ``Side of 
the Unpaired Quantity'' would mean the side of the Unpaired Quantity 
with the greater quantity of shares that are eligible to trade at the 
Imbalance Reference Price.
    The proposed Unpaired Quantity and Side of the Unpaired Quantity 
would be new information on Pillar, and would be available for Closing 
Auctions only. As noted above, Imbalance information on the Exchange 
means better-priced orders on one side of the market compared to both 
better-priced and at-price orders on the other side of the market. The 
Exchange believes that the Unpaired Quantity data would provide market 
participants with information regarding how many shares would be 
unpaired at the Imbalance Reference Price, which would be different 
from how the Imbalance would be calculated.\34\
---------------------------------------------------------------------------

    \34\ This proposed definition of ``Unpaired Quantity'' is 
comparable to how NYSE Arca and NYSE American calculate imbalance 
information under NYSE Arca Rule 7.35-E(a)(7) and NYSE American Rule 
7.35E(a)(7) (i.e., the ``number of buy (sell) shares that cannot be 
matched with sell (buy) shares''.)
---------------------------------------------------------------------------

     Proposed Rule 7.35(a)(4)(B)(i) would provide that for the 
Core Open and Trading Halt Auctions, the Paired Quantity would include 
all orders eligible to trade in an Auction. This proposed rule text is 
based on Rule 15(g)(1), which provides that Order Imbalance Information 
includes all interest eligible for execution in the opening transaction 
of the security in Exchange systems.
     Proposed Rule 7.35(a)(4)(B)(ii) would provide that for the 
Closing Auction, Paired and Unpaired Quantity would include MOC, LOC, 
and Closing IO Orders, and beginning five minutes before the scheduled 
end of Core Trading Hours, Closing D Orders. This proposed rule text is 
based in part on Rule 123C(6)(a)(i) and (ii), which describes the 
various data fields under the Current Auction Rules that include 
Auction-Only Orders.
    Proposed Rule 7.35(a)(4)(C) would define the term ``Continuous Book 
Clearing Price'' as the price at which all better-priced orders 
eligible to trade in an Auction on the Side of the Imbalance of such 
orders can be traded. As further proposed, if there is no Imbalance of 
all orders eligible to trade in the Auction, the Continuous Book 
Clearing Price would be the Imbalance Reference Price. This would be a 
new term for the Pillar Auction Rules and is based in part on Rule 
123C(6)(a)(i)(C), which refers to a data field indicating the price at 
which interest in the Display Book as well as closing-only orders may 
be executed in full,\35\ and Rule 15(g)(1), which refers to the ``price 
at which interest eligible to participate in the opening transaction 
may be executed in full.''
---------------------------------------------------------------------------

    \35\ As described above and consistent with Rule 123C(6), for 
the Closing Auction, only the Continuous Book Clearing Price would 
be based on all orders eligible to participate in the Closing 
Auction.
---------------------------------------------------------------------------

    Proposed Rule 7.35(a)(4)(D) would define the term ``Closing Only 
Interest Clearing Price'' as the price at which all

[[Page 6877]]

better-priced MOC and LOC Orders on the Side of the Total Imbalance can 
trade with both better-priced and at-priced contra-side MOC, LOC, and 
Closing IO Orders. As further proposed, if there is no Total Imbalance 
or there are no MOC or LOC Orders, the Closing Interest Only Clearing 
Price would be the Imbalance Reference Price. This would be a new term 
for the Pillar Auction Rules and is based in part on Rule 
123C(6)(a)(i)(B), which refers to ``a data field indicating the price 
at which closing-only interest . . . may be executed in full.''
    Proposed Rule 7.35(a)(6) would define the term ``Auction Processing 
Period'' to mean the period during which the applicable Auction is 
being processed. This proposed term is new for the Pillar Auction Rules 
and is based in part on the same term as used in NYSE Arca Rule 7.35-
E(a)(2) and NYSE American Rule 7.35E(a)(2). Because Auctions can be 
facilitated by a DMM on the Exchange, which differs from the electronic 
auction process on NYSE Arca and NYSE American, the Exchange proposes 
to further provide that for DMM-Facilitated Auctions, the Auction 
Processing Period includes the time when the DMM begins the process for 
conducting the Auction. As noted above, on the Trading Floor, the 
Exchange provides the DMM with a graphical user interface to manage the 
auction process, generally referred to as the ``opening'' or 
``closing'' template. If a DMM-Facilitated Auction is being manually 
conducted from the Trading Floor, as proposed, the Auction Processing 
Period would begin when the DMM begins using such template to conduct 
the Auction, which the Exchange proposes to refer to as the ``Pre-
Auction Freeze.'' Orders entered during such Auction Processing Period 
would be processed as described in proposed Rule 7.35(e).
    Proposed Rule 7.35(a)(7) would define the term ``Closing Auction 
Imbalance Freeze Time'' to mean 10 minutes before the scheduled close 
of trading. This proposed term would be new for the Pillar Auction 
Rules and is based on the numerous references to 3:50 p.m. in Rule 123C 
and Supplementary Material .40 to Rule 123C.\36\ The Exchange believes 
that the proposed definition would streamline the Pillar Auction Rules 
as compared to Rule 123C by using a single term to reference the period 
10 minutes before the scheduled close of trading and would obviate the 
need for the text from Supplementary Material .40 to Rule 123C to 
account for early scheduled closes. The Exchange further believes that 
the proposed term is consistent with the use of the term ``Auction 
Imbalance Freeze'' in the NYSE Arca and NYSE American auction 
rules.\37\
---------------------------------------------------------------------------

    \36\ The Exchange recently amended Rule 123C to change the time 
from 3:45 p.m. to 3:50 p.m. and plans to implement this change on 
April 1, 2019. See Securities Exchange Act Release No. 85021 
(January 31, 2019) (SR-NYSE-2018-58) (Approval Order) and Trader 
Update dated December 14, 2018, available here: https://www.nyse.com/publicdocs/nyse/markets/nyse/NYSE_MOC_LOC_Cutoff_Time_Change.pdf. In the Pillar Auction Rules, 
the Exchange similarly proposes to use 3:50 p.m., but instead of 
referring to the clock time in the rule, would refer to a time 
period before the scheduled close of trading that is defined as the 
``Closing Auction Imbalance Freeze Time.''
    \37\ See, e.g., NYSE American Rule 7.35E(d)(2) (describing the 
time for when the Closing Auction Imbalance Freeze would begin by 
referring to ten minutes before the scheduled time for the Closing 
Auction).
---------------------------------------------------------------------------

    Proposed Rule 7.35(a)(9) would define the term ``Floor Broker 
Interest'' to mean orders represented orally by a Floor broker at the 
point of sale. This would be a new term for the Pillar Auction Rules 
and is based in part on the reference to ``Floor broker interest 
entered manually by the DMM'' as described in Rule 123C(7)(a)(iii).
    Proposed Rule 7.35(a)(11) would define the term ``Last Sale Price'' 
to mean one of the following:
     Proposed Rule 7.35(a)(11)(A) would define the term 
``Consolidated Last Sale Price'' to mean the most recent consolidated 
last-sale eligible trade in a security on any market during Core 
Trading Hours on that trading day, and if none, the Official Closing 
Price from the prior trading day for that security. This proposed 
definition would be new for Pillar on the Exchange. Under this proposed 
definition, prior to 9:30 a.m., the Consolidated Last Sale Price would 
be the prior day's Official Closing Price for a security. However, 
after 9:30 a.m., if a security is trading on other exchanges, the 
Consolidated Last Sale Price would be the most recent consolidated 
last-sale eligible trade in such security on any exchange. The Exchange 
further proposes to provide that for a transferred security, the 
Consolidated Last Sale Price means the most recent consolidated last-
sale eligible trade in a security on any market during Core Trading 
Hours on that trading day, and if none, the official closing price from 
the prior trading day for that security from the exchange from which 
the security was transferred. This proposed rule text is based in part 
on Rule 15(g)(2)(B)(iv), which provides that for purposes of Order 
Imbalance Information, if the security is a transferred security, the 
reference price is the last reported sale price on the securities 
market from which the security was transferred prior to its first day 
of trading on the Exchange. The Exchange believes that the proposed 
definition of ``Consolidated Last Sale Price'' would obviate the need 
for this rule text. As described below, the Consolidated Last Sale 
Price may be used for determining the Imbalance Reference Price for a 
Core Open Auction or Trading Halt Auction.\38\
---------------------------------------------------------------------------

    \38\ Use of the Consolidated Last Sale Price for the Core Open 
or Trading Halt Auction would be a substantive difference in the 
Pillar Auction Rules from the Current Auction Rules. See discussion 
infra regarding proposed Rule 7.35A(e)(3).
---------------------------------------------------------------------------

     Proposed Rule 7.35(a)(11)(B) would define the term 
``Exchange Last Sale Price'' to mean the most recent trade on the 
Exchange of a round lot or more in a security during Core Trading Hours 
on that trading day, and if none, the Official Closing Price from the 
prior trading day for that security. This proposed definition would be 
new for the Pillar Auction Rules and is based in part on references to 
the term ``last sale price'' in Rules 123C(4)(a)(i) and (ii) and 
123C(6)(a)(iii)(A)-(C).
    Proposed Rule 7.35(a)(12) would define the term ``Legitimate 
Error'' to mean an error in any term of an order, such as price, number 
of shares, side of the transaction (buy or sell), or identification of 
the security. This proposed definition would be new for the Pillar 
Auction Rules and is based in part on Rule 123C(1)(c), which defines 
the term ``Legitimate Error'' to mean ``an error in any term of a MOC 
or LOC order, such as price, number of shares, side of the transaction 
(buy or sell) or identification of the security.'' Unlike the Current 
Auction Rules, use of this term in the Pillar Auction Rules would not 
be limited to MOC and LOC Orders.\39\
---------------------------------------------------------------------------

    \39\ See discussion infra regarding proposed Rules 
7.35B(a)(1)(C) and 7.35B(f)(2)(A) relating to the proposed use of 
the term ``Legitimate Error.''
---------------------------------------------------------------------------

    Auction Ranking. Proposed Rule 7.35(b) would set forth the general 
rules for how different types of orders would be ranked for purposes of 
how they are included in Auction Imbalance Information or for an 
Auction allocation.
    First, proposed Rule 7.35(b)(1) would provide that orders would be 
ranked based on the price at which they would participate in an 
Auction. The price at which an order would be ranked would be used to 
determine whether it is a better-priced or an at-priced order. The 
proposed rule would specify which price would be applicable to 
different types of orders, as follows:
     Proposed Rule 7.35(b)(1)(A) would provide that for Limit 
Orders, the ranked price would be the limit price of

[[Page 6878]]

an order.\40\ The Limit Orders that would be eligible to participate in 
Auctions include varying order types that are subject to repricing, 
such as a Non-Routable Limit Order, ALO, and Primary Pegged Order. 
Under the Pillar Auction Rules, such orders would be ranked for 
purposes of both Auction Imbalance Information and Auction allocation 
at their limit price, which represents current functionality.\41\
---------------------------------------------------------------------------

    \40\ The term ``limit price'' is defined in Rule 7.36(a)(2) to 
mean the highest (lowest) specified price at which a Limit Order to 
buy (sell) is eligible to trade.
    \41\ For example, under Rule 13(e)(1)(A), an ALO Order may 
participate in openings, reopenings, or closing, but the ALO 
designation shall be ignored, which means that the order would 
participate in such transactions at its limit price.
---------------------------------------------------------------------------

     Proposed Rule 7.35(b)(1)(B) would provide that for Opening 
D Orders, described above, the ranked price would be the undisplayed 
discretionary price. This would be new text for Pillar Auction Rules 
and is based on how d-Quotes designated for the opening or reopening 
transaction are ranked for purposes of Order Imbalance Information 
under Rule 15(g) and allocation in an auction under Rule 115A.
     Proposed Rule 7.35(b)(1)(C) would provide that for Closing 
D Orders, described above, the ranked price would be based on a 
specified time. As proposed, up to five minutes before the end of Core 
Trading Hours, the ranked price of a Closing D Order would be the 
order's limit price.\42\ As further proposed, beginning five minutes 
before the end of Core Trading Hours, the ranked price of a Closing D 
Order would be the order's undisplayed discretionary price.\43\ This 
proposed rule text is based on how currently, pursuant to Rule 
123C(6)(a)(ii), at 3:55 p.m., Order Imbalance Information begins 
including d-Quotes eligible to participate in the closing transaction 
at their undisplayed discretionary price. As described below, on 
Pillar, the Exchange proposes to retain this functionality for Closing 
D Orders. To reflect this functionality, and to reflect that prior to 
3:55 p.m., Closing D Orders would be eligible to trade at their limit 
price,\44\ the Exchange proposes that the price at which such orders 
would be ranked would change once they are included in Auction 
Imbalance Information at their undisplayed discretionary price.
---------------------------------------------------------------------------

    \42\ See proposed Rule 7.35(b)(1)(C)(i).
    \43\ See proposed Rule 7.35(b)(1)(C)(ii).
    \44\ As described above, pursuant to proposed Rule 
7.31(c)(2)(C)(ii), on arrival, Closing D Orders would be eligible to 
trade based on their limit price.
---------------------------------------------------------------------------

     Proposed Rule 7.35(b)(1)(D) would provide that the ranked 
price for DMM Interest would be the Imbalance Reference Price (for when 
DMM Interest is included in the Auction Imbalance Information) or the 
Auction Price (for how DMM Interest is ranked for an Auction 
allocation). As described in more detail below, regardless of the limit 
price of DMM Interest, it will never be considered ``better-priced'' 
interest or be guaranteed to participate in an Auction. Accordingly, 
for purposes of Auctions, DMM Interest is always considered at-priced 
interest. The Exchange therefore believes that the ranked price of such 
interest should be either the Imbalance Reference Price or the Auction 
Price so that it is not included on the Side of the Imbalance for the 
Imbalance calculation.
    Second, proposed Rule 7.35(b)(2) would provide that the working 
time for an order participating in an Auction would be its entry time, 
which would be used for determining the relative time priority of such 
orders on the applicable allocation wheel under Rule 7.37(b). Use of 
the entry time would be new for NYSE on Pillar. Currently, the last 
time stamp associated with an order is used for opening, reopening, and 
closing transactions. The Exchange proposes to change this 
functionality on Pillar because an order would be participating at its 
limit price in an auction, and not its last working price (if it is an 
order that reprices), and therefore the entry time is reflective of the 
relative time priority of multiple orders.
    The rule would further provide that the working time of a Closing D 
Order would be the later of its entry time or five minutes before the 
end of Core Trading Hours.\45\ The Exchange believes it would be 
appropriate to assign a working time to such orders based on when they 
would be included in the Auction Imbalance Information at their 
undisplayed discretionary price. As noted above, the Exchange would 
begin including the undisplayed discretionary price of Closing D Orders 
in Auction Imbalance Information five minutes before the scheduled 
close of trading.
---------------------------------------------------------------------------

    \45\ For example, a Closing D Order entered at 3:00 p.m. would 
have a working time of 3:55 p.m. and a Closing D Order entered at 
3:57 p.m. would have a working time of 3:57 pm.
---------------------------------------------------------------------------

    The Exchange also proposes that if a short sale order is repriced 
to a Permitted Price during a Short Sale Period pursuant to Rule 
7.16(f), the time of such repricing would be considered the working 
time for such an order participating in an Auction. The Exchange 
believes that the time of such repricing should be used as the working 
time rather than the time of entry because such order would participate 
in an Auction at the Permitted Price, and not at the limit price of the 
order.
    Auction Imbalance Information. Proposed Rule 7.35(c) would provide 
that the Exchange disseminates Auction Imbalance Information via a 
proprietary data feed during the times specified in the Rule 7.35 
Series. This proposed rule text would be new for the Pillar Auction 
Rules and is based in part on NYSE Arca Rule 7.35-E(a)(4)(C) and NYSE 
American Rule 7.35E(a)(4)(C). This proposed rule text is also based on 
Rule 15(g) and 123C(6), which provide that the Exchange may make 
available Order Imbalance Information.
    Proposed Rule 7.35(c)(1) would provide that Auction Imbalance 
Information would be updated at least every second, unless there is no 
change to the information. This proposed rule is based on NYSE Arca 
Rule 7.35-E(a)(4)(A) and NYSE American Rule 7.35E(a)(4)(A) and would be 
a substantive difference from how the Exchange currently functions.\46\ 
The Exchange believes that disseminating Auction Imbalance Information 
at least every second, rather than the five-second time intervals (or 
longer) under the current rules, would provide member organizations 
with more updated information leading into each respective Auction. The 
Exchange further believes that this proposed substantive difference 
from the Current Auction Rules would standardize the manner of 
dissemination of Auction Imbalance Information across affiliated 
exchanges.
---------------------------------------------------------------------------

    \46\ Pursuant to Rule 15(g)(3), Order Imbalance Information 
before the opening is disseminated approximately every five minutes 
between 8:30 a.m. and 9:00 a.m., approximately every minute between 
9:00 a.m. and 9:20 a.m., and approximately every five seconds 
between 9:20 a.m. and the opening of trading in that security. 
Pursuant to Rule 123C(6)(a)(iv), Order Imbalance Information is 
disseminated approximately every five seconds between 3:50 p.m. and 
4:00 p.m.
---------------------------------------------------------------------------

    Proposed Rule 7.35(c)(2) would provide that Auction Imbalance 
Information would continue to be disseminated until the Auction begins. 
This proposed rule text is new for the Pillar Auction Rules. This rule 
is based in part on Rule 15(g)(3)(C) (and Supplementary Material .10 to 
Rule 15 relating to reopening transactions), which provides that Order 
Imbalance Information continues to be disseminated until the opening or 
reopening of trading in that security. Accordingly, for the Core Open 
Auction and Trading Halt Auction, the functionality would not change on 
Pillar.
    However, this proposed rule text would be a substantive difference 
for Closing Auctions. Currently, Rule

[[Page 6879]]

123C(6)(a)(iv) provides that Order Imbalance Information for the close 
is disseminated until 4:00 p.m. The Exchange therefore stops 
disseminating this information at 4:00 p.m., regardless of the timing 
of the closing transaction. In the Pillar Auction Rules, the Exchange 
proposes that for the Closing Auction, the Exchange would continue 
disseminating Auction Imbalance Information until the Closing Auction 
begins, which is after 4:00 p.m.\47\ As discussed below, Floor Broker 
Interest that was represented by the end of Core Trading Hours will be 
entered electronically into Exchange systems after 4:00 p.m. and such 
interest may change the Auction Imbalance Information.\48\ The Exchange 
believes that it would promote transparency and provide market 
participants with greater specificity regarding a potential Closing 
Auction Price for such Floor Broker Interest to be included in the 
Auction Imbalance Information after the scheduled end of Core Trading 
Hours.
---------------------------------------------------------------------------

    \47\ As discussed below, because of the manual nature of the 
Closing Auction, the Auction Processing Period for such Auction 
begins after 4:00 p.m.
    \48\ See discussion infra regarding proposed Rule 7.35B(a)(1).
---------------------------------------------------------------------------

    Proposed Rule 7.35(c)(3) would provide that the Exchange would not 
disseminate Auction Imbalance Information if a security is an IPO or a 
Direct Listing and has not had its IPO Auction or Direct Listing 
Auction. This proposed rule text would be new for the Pillar Auctions 
Rules and is based in part on how Rule 15(g) functions for IPOs.\49\ 
The Exchange proposes non-substantive differences to use Pillar 
terminology to describe this functionality and to extend this 
functionality to Direct Listings as well.
---------------------------------------------------------------------------

    \49\ See Securities Exchange Act Release No. 74837 (April 29, 
2015), 80 FR 25741 (May 5, 2015) (SR-NYSE-2015-19) (Notice of filing 
and immediate effectiveness of proposed rule change to reflect that 
Exchange systems will not publish Order Imbalance Information for an 
IPO.)
---------------------------------------------------------------------------

    Openings and Reopenings in the Last Ten Minutes of Trading. 
Proposed Rule 7.35(d) would provide that the Exchange would not open or 
reopen a security that has not yet opened or is halted or paused and 
would not transition to continuous trading if such opening or reopening 
would be in the last ten minutes of trading before the end of Core 
Trading Hours. This proposed rule text would be new for the Pillar 
Auction Rules and is based in part on the first sentence of NYSE Arca 
Rule 7.35-E(e)(10) and NYSE American Rule 7.35E(e)(10), which both 
provide that if the re-opening time for a Trading Halt Auction would be 
in the last ten minutes of trading before the end of Core Trading 
Hours, NYSE Arca and NYSE American will not conduct a Trading Halt 
Auction in that security and will not transition to continuous trading. 
This proposed rule text is also based on Rule 80C(b)(2), which provides 
that if the reopening following a Trading Pause would be in the last 
ten minutes of trading before the end of regular trading hours, the 
Exchange will not reopen trading in that security and will not 
transition to continuous trading.
    The Exchange proposes a substantive difference for the first 
sentence of Rule 7.35(d) as compared to the NYSE Arca and NYSE American 
versions of the rule to reflect that on the Exchange, a security may 
not be opened by 3:50 p.m.\50\ The Exchange proposes that if a security 
has not opened or reopened before the last ten minutes of trading 
before the end of Core Trading Hours, the Exchange will not open that 
security during that period.
---------------------------------------------------------------------------

    \50\ Both NYSE Arca and NYSE American transition electronically 
to the Core Trading Session at 9:30 a.m. By contrast, DMM-
Facilitated Core Open Auctions do not require the DMM to open a 
security if there is no interest in such security. Alternately, a 
security may be the subject of a regulatory halt at that time.
---------------------------------------------------------------------------

    Proposed Rule 7.35(d) would further provide how the Exchange would 
process such security if it is eligible to trade in the last ten 
minutes of trading before the end of Core Trading Hours, i.e., it is 
not subject to a regulatory halt, as follows:
     Proposed Rule 7.35(d)(1) would provide that the Exchange 
would remain unopened, halted, or paused and would disseminate an 
auction indicator that the security is eligible to be closed as 
provided for in the Rule 7.35 Series. This proposed rule text is based 
on the second sentence of NYSE Arca Rule 7.35-E(e)(10) and NYSE 
American Rule 7.35E(e)(10) and the definition of ``Auction Indicator'' 
in NYSE Arca Rule 7.35-E(a)(13) and NYSE American Rule 7.35E(a)(13) 
with a proposed substantive difference that the Exchange would 
disseminate an auction indicator only if such security would be 
eligible to be closed. The Exchange believes that this proposed auction 
indicator would provide transparency to member organizations whether a 
Closing Auction would be conducted in a security that has not opened or 
reopened for trading by the last ten minutes of trading before the end 
of Core Trading Hours.
     Proposed Rule 7.35(d)(2) would provide that MOO Orders, 
LOO Orders, Opening D Orders, and Primary Pegged Orders would be 
cancelled. This proposed rule text is based in part on NYSE Arca Rule 
7.35-E(e)(10)(A) and NYSE American Rule 7.35E(e)(10)(A) with a proposed 
substantive difference to reference Opening D Orders and Primary Pegged 
Orders, which, as discussed above, are not eligible to participate in 
the Closing Auction.\51\
---------------------------------------------------------------------------

    \51\ See proposed Rules 7.31(c)(1) and 7.31(h)(2).
---------------------------------------------------------------------------

     Proposed Rule 7.35(d)(3) would provide that the Exchange 
would begin disseminating Closing Auction Imbalance Information. This 
proposed rule text would be new for Pillar Auction Rules and is 
intended to provide transparency in Exchange rules regarding which 
Auction Imbalance Information would be disseminated by the Exchange.
    Order Processing During an Auction Processing Period. The Exchange 
proposes that the manner by which new orders and requests to cancel, 
cancel and replace, or modify an order would be processed during an 
Auction Processing Period would be the same as how such instructions 
are processed on its affiliated exchanges, with specified differences 
to reflect the Exchange's model to have DMM-facilitated auctions.
    Proposed Rules 7.35(e), 7.35(e)(1), and 7.35(e)(2) are based on 
NYSE Arca Rules 7.35-E(g), 7.35-E(g)(1), and 7.35-E(g)(2) and NYSE 
American Rules 7.35E(g), 7.35E(g)(1), and 7.35(g)(2) without any 
differences. Specifically, as proposed, new orders received during the 
Auction Processing Period would be accepted but would not be processed 
until after the Auction Processing Period. In other words, such orders 
would not be eligible to participate in an Auction, which is how order 
processing functions currently on the Exchange.
    The Exchange proposes additional text for proposed Rule 7.35(e) as 
compared to the rules of NYSE Arca and NYSE American to reflect 
differences in how DMM-Facilitated Auctions would function, and 
specifically, that the Auction Processing Period on the Exchange would 
include the Pre-Auction Freeze. As proposed, DMM Auction Liquidity, 
certain DMM Orders, and Floor Broker Interest entered during the Pre-
Auction Freeze would be eligible to participate in the applicable 
Auction. Any other orders entered during the Pre-Auction Freeze would 
be considered entered during the Auction Processing Period, and 
therefore would be accepted but not eligible to participate in an 
Auction.
    The Exchange proposes this difference because during a DMM-
Facilitated Auction, the DMM uses the respective opening or closing 
template to enter DMM Auction Liquidity, DMM Orders, or Floor Broker 
Interest (for the

[[Page 6880]]

Closing Auction only). When facilitating an Auction electronically, the 
DMM is similarly able to enter DMM Auction Liquidity and certain DMM 
Orders that would be eligible to participate in the applicable 
Auction.\52\ Accordingly, this proposed rule change would reflect in 
Pillar Auction Rules how DMM-facilitated auctions would function, which 
would differ from how the NYSE Arca and NYSE American electronic 
auctions function.
---------------------------------------------------------------------------

    \52\ The reference to ``certain'' DMM Orders is to distinguish 
DMM Orders that are entered via the algorithmic interface for the 
DMM to facilitate the Auction pursuant to Rules 104(b) and (a)(2) or 
(3), described above. DMM Orders entered via this functionality 
would be accepted during the Pre-Auction Freeze and would be 
eligible to participate in the Auction. DMM Orders not entered via 
this functionality would be accepted during the Auction Processing 
Period, but would not be eligible to participate in the applicable 
Auction, as provided for in the first sentence of proposed Rule 
7.35(e). In either case, DMM Orders would mean an order as defined 
in Rule 7.31.
---------------------------------------------------------------------------

    The Exchange proposes an additional difference as compared to the 
NYSE Arca and NYSE American rules to reflect that an order instruction 
received during the Pre-Auction Freeze for the Closing Auction would be 
processed on arrival if it relates to Floor Broker Interest entered 
before the Pre-Auction Freeze. In proposed Rule 7.35(e), an ``order 
instruction'' would be defined for purposes of proposed Rules 7.35(e) 
and (f) to mean a request to cancel, cancel and replace, or modify an 
order, which is based on the NYSE Arca and NYSE American use of such 
term. As described in greater detail below, Floor Broker Interest for 
the Closing Auction would be electronically entered after the end of 
Core Trading Hours, and there would be specified circumstances when 
such interest could be cancelled, which the DMM would have to 
process.\53\ Because the DMM would be processing such cancellation 
requests, the Exchange proposes that such requests would be accepted 
during the Pre-Auction Freeze, which is controlled by the DMM.
---------------------------------------------------------------------------

    \53\ See discussion infra regarding proposed Rule 7.35B(a)(1).
---------------------------------------------------------------------------

    Transition to Continuous Trading. The Exchange also proposes that 
the manner by which the Exchange would transition to continuous trading 
following an Auction would be based on existing Pillar functionality. 
Accordingly, proposed Rule 7.35(f) and subparagraphs (1)-(3) would be 
based on NYSE Arca Rule 7.35-E(h) and subparagraphs (1)-(3) and NYSE 
American Rule 7.35E(h) and subparagraphs (1)-(3) with the following 
substantive differences.
     First, current NYSE Arca Rule 7.35-E(h)(2)(A) provides 
that during the transition to continuous trading, an order instruction 
(as defined in NYSE Arca Rule 7.35-E(g)) received during the Auction 
Imbalance Freeze, the transition to continuous trading, or the Auction 
Processing Period would be processed in time sequence with the 
processing of orders as specified in NYSE Arca Rules 7.35-E(h)(3)(A) or 
(B) if it relates to an order that was received before the Auction 
Processing Period. Proposed Rule 7.35(f)(2)(A) would not include text 
that is not applicable to the NYSE (e.g., Auction Imbalance Freeze). 
The Exchange proposes an additional difference because the rule would 
provide that the processing of order instructions described in that 
sentence would also apply to orders that have already transitioned to 
continuous trading. This is intended to promote clarity and 
transparency in Exchange rules of when an order instruction (as defined 
in proposed Rule 7.35(e)) would be applied to an order. The Exchange 
proposes a corollary difference to proposed Rule 7.35(f)(2)(B) as 
compared to NYSE Arca Rule 7.35-E(h)(2)(B) to provide that subparagraph 
of proposed Rule 7.35(f)(2)(B) would apply only to an order instruction 
(as defined in Rule 7.35(e)) for an order that has not yet transitioned 
to continuous trading. The Exchange also proposes to make a clarifying 
difference from the NYSE Arca version to add the word ``either'' before 
the phrase ``the Auction Processing Period or the transition to 
continuous trading.''
     Second, NYSE Arca Rule 7.35-E(h)(3) sets forth how orders 
are processed when transitioning to continuous trading from a prior 
trading session or following an auction. Because the Exchange only has 
one trading session for Exchange-listed securities, the Exchange does 
not propose to include text in proposed Rule 7.35(f)(3) from the NYSE 
Arca rule referencing transitioning to continuous trading from a prior 
trading session. The Exchange further proposes that proposed Rule 
7.35(f)(3)(A)(i) would provide that reserve interest that replenishes 
the display quantity of a routable Reserve Order would route, if 
marketable against protected quotations on Away Markets. This proposed 
rule text differs from NYSE Arca Rule 7.35-E(h)(3)(A)(i) because the 
Exchange would not include the modifier ``fully-executed'' before the 
reference to ``display quantity.'' The Exchange has amended its Reserve 
Order functionality and specifically the circumstances when a Reserve 
Order would be replenished, and the reference to ``fully-executed'' is 
now moot.\54\
---------------------------------------------------------------------------

    \54\ See Securities Exchange Act Release No. 83768 (August 3, 
2018), 83 FR 39488 (August 9, 2018) (SR-NYSE-2018-26) (Approval 
Order).
---------------------------------------------------------------------------

     Third, NYSE Arca Rule 7.35-E(h)(3)(B) provides that 
unexecuted orders that were not eligible to trade in the prior trading 
session (or were received during a halt or pause) or that were received 
during the Auction Processing Period, will be assigned a new working 
time at the end of the Auction Processing Period in time sequence 
relative to one another based on original entry time. The Exchange's 
proposed Rule 7.35(f)(3)(B) would differ from NYSE Arca Rule 7.35-
E(h)(3)(B) because it would not include references to orders received 
during a halt or pause or orders that were not eligible to trade in the 
prior trading session (because the Exchange has only one trading 
session for Exchange-listed securities). The Exchange proposes that the 
working time for orders received during a halt or pause would be the 
original entry time, as provided for in Rule 7.36(f)(1), and therefore 
would not have to be discussed separately in proposed Rule 
7.35(f)(3)(B). This proposed difference is based on proposed Rule 
7.35(b)(2), discussed above, that the working time for an order 
participating in an Auction would be its entry time. The Exchange also 
proposes a substantive difference to proposed Rule 7.35(f)(3)(B) as 
compared to the NYSE Arca and NYSE American versions of the rule to 
reflect that DMM After-Auction Orders would be processed before other 
orders. As discussed above, DMM After-Auction Orders are intended to 
help facilitate the DMM's compliance with the Rule 104(f)(ii) 
obligation to maintain continuity with reasonable depth, particularly 
after an Auction. Accordingly, the Exchange proposes that when it 
begins processing orders that were received during the Auction 
Processing Period, DMM After-Auction Orders would be processed 
first.\55\ The Exchange believes that because the DMM has an obligation 
to maintain price continuity, the DMM After-Auction Orders would be 
more likely to be priced to closely correlate to the Auction Price and 
therefore quoting this interest before other orders that were received 
during the Auction Processing Period would promote a fair and orderly

[[Page 6881]]

transition from the Auction to continuous trading.\56\
---------------------------------------------------------------------------

    \55\ As proposed in Rule 7.35(f)(3)(A), the first quote that 
would be published after an Auction would be based on unexecuted 
orders that were eligible to participate in the Auction but did not. 
Proposed Rule 7.35(f)(3)(B) concerns orders that were not eligible 
to participate in the Auction and how they would be released into 
continuous trading.
    \56\ The Exchange notes that pursuant to proposed Rule 
7.35(f)(3)(A), unexecuted orders that were eligible to trade in the 
Auction would be quoted ahead of orders referenced in proposed Rule 
7.35(f)(3)(B). Accordingly, DMM Auction-Only Orders would not be 
quoted ahead of orders that arrived before the Auction Processing 
Period.
---------------------------------------------------------------------------

     Fourth, the Exchange proposes a non-substantive change 
that proposed Rule 7.35(f)(3)(D) would be based on the last stand-alone 
paragraph NYSE Arca Rule 7.35-E(h)(3)(C), without any substantive 
differences.
     Finally, the Exchange proposes additional differences 
between proposed Rules 7.35(e) and (f) as compared to NYSE Arca Rules 
7.35-E(g) and (h) and NYSE American Rules 7.35E(g) and (h) to reflect 
the differences between the operation of the Exchange and those 
markets. Specifically, because these proposed rules would be applicable 
only to Exchange-listed securities and such securities would be 
eligible to trade during the Core Trading Session only, there is no 
Auction Imbalance Freeze before the Core Open Auction, and the Exchange 
does not offer the Proactive if Locked/Crossed Modifier, the Exchange 
proposes differences from the NYSE Arca and NYSE American rules to 
remove references relating to transitions of trading sessions and the 
Early Open Auction, Auction Imbalance Freezes, the Proactive if Locked/
Crossed Modifier, and also to use Pillar terminology applicable to the 
Exchange.
    Short Sale Period. Proposed Rule 7.35(g) would provide that during 
a Short Sale Period, as defined in Rule 7.16(f), Sell Short MOO and MOC 
Orders in Auction-Eligible Securities would be ranked for purposes of 
Auction Imbalance Information and allocated in an Auction as Priority 
2- Display Orders at the Permitted Priced (as defined in Rule 
7.16(f)).\57\ This proposed rule text is based in part on Commentary 
.01 to NYSE Arca Rule 7.35-E with a substantive difference to reference 
MOO and MOC Orders specifically, rather than referring to Market Orders 
more generally, and not to reference Market Imbalance, which would not 
be provided on the Exchange. The Exchange proposes non-substantive 
differences to update the order of the rule text, as compared to the 
NYSE Arca Rule, to use NYSE Pillar terminology.
---------------------------------------------------------------------------

    \57\ See Proposed Rule 7.35(g)(1).
---------------------------------------------------------------------------

    Proposed Rule 7.35(g)(2) would provide that sell short orders that 
are included in the Auction Imbalance Information would be adjusted to 
a Permitted Price as the NBB moves both up and down. This proposed rule 
text is based on Commentary .01(b) to NYSE Arca Rule 7.35-E.
    Miscellaneous. Proposed Rule 7.35(h) would provide that whenever in 
the judgment of the Exchange the interests of a fair and orderly market 
so require, the Exchange may adjust the timing of or suspend the 
auctions set forth in this Rule with prior notice to member 
organizations. This proposed rule text would be new for Pillar Auction 
Rules and is based on NYSE Arca Rule 7.35-E(i) and NYSE American Rule 
7.35E(i) with a non-substantive difference to reference member 
organizations rather than ETP Holders.
    Proposed Rule 7.35(i) would provide that for purposes of Rule 
611(b)(3) of Regulation NMS, an Auction is a single-priced opening, 
reopening, or closing transactions and may trade through any Away 
Market's Protected Quotations. This proposed rule text would be new for 
Pillar Auction Rules and is based on both Rule 611(b)(3) of Regulation 
NMS \58\ and NYSE Arca Rule 7.35-E(j) and NYSE American Rule 7.35E(j) 
without any substantive differences.
---------------------------------------------------------------------------

    \58\ 17 CFR 242.611(b).
---------------------------------------------------------------------------

Proposed Rule 7.35A (DMM-Facilitated Core Open and Trading Halt 
Auctions)
    Proposed Rule 7.35A would set forth the process for DMM-facilitated 
Core Open and Trading Halt Auctions.
    DMM and Floor Broker Responsibilities. Proposed Rule 7.35A(a) would 
set forth both the DMM and Floor broker responsibilities for the 
opening and reopening of securities, and is based on Rule 123D(a)(1) 
and 123D(b). Rule 123D(b) sets forth responsibilities for both DMMs and 
Floor brokers relating to their unique roles on the Trading Floor with 
respect to the opening and reopening of securities. On Pillar, the 
Exchange will continue to operate a Trading Floor under substantively 
the same rules as the Current Auction Rules, and therefore the Exchange 
proposes to include the responsibilities described in Rule 123D(b) in 
the Pillar Auction Rules, modified as described below.
    Proposed Rule 7.35A(a) would provide that it is the responsibility 
of each DMM to ensure that registered securities open as close to the 
beginning of Core Trading Hours as possible or reopen at the end of the 
halt or pause, while at the same time not unduly hasty, particularly 
when at a price disparity from the Consolidated Last Sale Price. This 
proposed rule text is based on Rule 123D(a)(1) with a non-substantive 
difference to use Pillar terminology.
    The Exchange proposes a substantive difference to proposed Rule 
7.35A(a) as compared to Rule 123D(a)(1). Specifically, under the 
current rule, for the opening, the DMM should look at the prior close's 
price for determining whether the opening price would be at a price 
disparity. For reopenings, the DMM should look at the last price on the 
Exchange to determine whether the reopening price would be at a price 
disparity. On Pillar, the Exchange proposes that for both the Core Open 
and Trading Halt Auctions, the Consolidated Last Sale Price should be 
used to determine whether there is a price disparity.
    For a Core Open Auction that takes place at 9:30 a.m. (e.g., if a 
DMM facilitates the Core Open Auction electronically), this proposed 
rule change would have minimal difference from the current rule because 
at that time, the definition of Consolidated Last Sale Price means the 
Official Closing Price of a security, which may be the prior close's 
price on the Exchange.\59\ For a Core Open Auction that takes place 
after 9:30 a.m. and for which there are consolidated last-sale eligible 
trades on other exchanges, this proposed rule change would represent a 
substantive difference because the DMM should look at any price 
disparity between the proposed Core Open Auction Price and how the 
security is already trading on other markets, rather than the prior 
close price. The Exchange proposes a similar difference for Trading 
Halt Auctions, as the DMM should look at the Consolidated Last Sale 
Price, rather than the Exchange's last sale price, to determine whether 
there is a price disparity. The Exchange believes these proposed 
substantive differences would reflect that there may be more recent 
trading activity on another exchange, and such price may reflect a more 
recent valuation for a security with which to assess whether an Auction 
Price would be at a price disparity.
---------------------------------------------------------------------------

    \59\ See proposed Rule 7.35(a)(11(a), discussed supra. As noted 
above, if there is no Closing Auction of one round lot or more, the 
Official Closing Price would be based on the last consolidated last-
sale eligible price rather than the last Exchange sale price, and in 
such scenario, use of the Official Closing Price in proposed Rule 
7.35A(a) would differ from the price that would be used under Rule 
123D(a)(1).
---------------------------------------------------------------------------

    Proposed Rules 7.35A(a)(1)-(5) are based on 123D(b) as follows:
     Proposed Rule 7.35A(a)(1) would provide that openings and 
reopenings should reflect the professional assessment of market 
conditions at the time, and appropriate consideration of the balance of 
supply and demand as reflected by orders in the Exchange

[[Page 6882]]

Book. This proposed rule text is based on the first sentence of the 
first paragraph of Rule 123D(b), with non-substantive differences to 
use Pillar terminology and streamline the rule text.
     Proposed Rule 7.35A(a)(2) would provide that to the best 
of their ability, at the point of sale on the Trading Floor, DMMs 
should provide timely and impartial information at all phases of the 
opening or reopening process and that DMM units are responsible for 
ensuring that adequate personnel are available to assist in the fair 
and orderly opening or reopening of all securities registered with that 
DMM unit. This proposed rule text is based on the second and third 
sentences of the first paragraph of Rule 123D(b) with non-substantive 
differences to use Pillar terminology and streamline the rule text.
     Proposed Rule 7.35A(a)(3) would relate to Floor broker 
responsibilities and would provide that:

    Floor brokers should make every effort to ascertain their 
customers' interest as early as possible and to inform the DMM so 
that such interest can be factored into the opening or reopening 
process. Floor brokers should communicate to their customers the 
problems caused by delaying their interest until the last minute. 
Floor brokers should not expect to be able to delay the opening or 
reopening to accommodate customer reactions to changing prices. Once 
a relatively narrow range of opening or reopening possibilities is 
available, brokers and their customers should have sufficient 
information to electronically enter an order with a firm limit 
price.

    This proposed rule text is based on the second, third, fifth, and 
sixth sentences of the second paragraph of Rule 123D(b) with non-
substantive differences to use Pillar terminology and streamline the 
rule text. The Exchange does not propose to include the balance of the 
second paragraph of Rule 123D(b) in Rule 7.35A(a)(3) as such rule text 
is either duplicative of the rule text proposed to be retained or 
obsolete in today's trading environment (e.g., reference to orders or 
cancellations ``merely dropped on the counter'').
     Proposed Rule 7.35A(a)(4) would provide that Floor 
Officials participate in the opening and reopening process to provide 
an impartial professional assessment of unusual situations, as well as 
to provide guidance with respect to pricing when a significant 
disparity in supply and demand exists. This proposed rule text is based 
on the first sentence of the third paragraph of Rule 123D(b) with non-
substantive differences to use Pillar terminology and streamline the 
rule text. The balance of proposed Rule 7.35A(a)(4) would provide that 
DMMs should consult with a Floor Official under specified 
circumstances, which is based on the last sentence of the first 
paragraph and the fifth paragraph of Rule 123D(b).\60\
---------------------------------------------------------------------------

    \60\ Rules 46, 46A, and 47 specify how Floor Officials, Senior 
Floor Officials, Executive Floor Officials, Floor Governors, and 
Executive Floor Governors are appointed and their general authority 
under Exchange rules.
---------------------------------------------------------------------------

    The Exchange proposes to specify in proposed Rules 7.35A(a)(4)(A)-
(D) the specific circumstances when a DMM should consult with a Floor 
Official:
    [cir] If a security would be opened more than 30 minutes after the 
scheduled beginning of Core Trading Hours, which the Exchange proposes 
to define as a ``Delayed Opening'' (see proposed Rule 7.35A(a)(4)(A)). 
This proposed rule text is based on the last sentence of the first 
paragraph of Rule 123D(b), which refers to delayed openings, and Rule 
15(b)(1), which references 10:00 a.m. as a time by when an opening 
should occur before a pre-opening indication would be required, and 
thus constitutes a delayed opening.
    [cir] If it is anticipated that the opening or reopening price 
would be at a significant disparity from the Consolidated Last Sale 
Price for such security (see proposed Rule 7.35A(a)(4)(B)). This 
proposed rule text is based on the fifth paragraph of Rule 123D(b) with 
the substantive difference described above that the DMM should use the 
Consolidated Last Sale Price rather than the prior close price (for 
openings) or last price on the Exchange (for reopenings).
    [cir] If there is a significant imbalance (see proposed Rule 
7.35A(a)(4)(C)). This proposed rule text is based on the fifth 
paragraph of Rule 123D(b).
    [cir] In unusual situations (see proposed Rule 7.35A(a)(4)(D)). 
This proposed rule text is based on the last sentence of the first 
paragraph of Rule 123D(b).
     Proposed Rule 7.35A(a)(5) would provide that in 
determining when to open or reopen a security in circumstances 
described in Rule 7.35A(a)(4), a DMM should make every effort to 
balance timeliness with the opportunity for customer reaction and 
participation. The rule would further provide that when the DMM and 
Floor Official agree that all participants have had a reasonable 
opportunity to participate, the DMM should open or reopen the security. 
In addition, the rule would provide that the DMM has ultimate 
responsibility for opening or reopening a security and while a Floor 
Official's approval may be a mitigating factor, it would not exonerate 
the DMM if performance has been deemed unsatisfactory. This proposed 
rule text is based on the last paragraph of Rule 123D(b) and the last 
sentence of the third paragraph of Rule 123D(b). The Exchange proposes 
non-substantive differences to use Pillar terminology and streamline 
the rule text.
    Proposed Rule 7.35A(a)(5) and subparagraphs (A)-(E) would further 
provide that in unusual market situations, the DMM should consider the 
following areas as indicative of poor DMM performance: (A) An opening 
or reopening price change that is not in proportion to the size of an 
imbalance; (B) absence of a pre-opening indication before a large 
Auction Price change; (C) inadequate support after a large Auction 
Price change, i.e., lack of sufficient continuity and depth in the 
aftermarket; (D) absence of trading without good cause or Floor 
Official approval (or an unjustified or unreasonably delayed opening or 
halt in trading); and (E) not obtaining appropriate Floor Official 
approval for opening delays. This proposed rule text is based on the 
fourth paragraph of Rule 123D(b) and related subparagraphs, with non-
substantive differences to use Pillar terminology and streamline the 
rule text. In addition, the Exchange does not propose retaining text 
relating to obtaining appropriate Floor Official approvals for trading 
halts and wide price variations, as the Exchange no longer requires 
Floor Official approval for such scenarios.
    Opening Without a Trade. Proposed Rule 7.35A(b) would provide that 
if there is no interest to conduct a Core Open Auction (for openings) 
or Trading Halt Auction (for reopenings), a DMM may open or reopen a 
registered security with a quote. This proposed rule text is based on 
Rule 123D(a)(1)(A), with non-substantive differences to use Pillar 
terminology.
    Currently, there are circumstances when a security may not open on 
either a trade or a quote. This can occur when there is a new listing 
on the Exchange that does not have public pricing information or 
trading interest, such as the listing of a security on a when-issued 
basis. In such circumstances, under current rules, a DMM will publish a 
pre-opening indication if such security is not opened by 10:00 a.m., 
i.e., a Delayed Opening, but such pre-opening indication may be wide 
because there is no buy and sell interest in the security entered on 
the Exchange. Rather, that pre-opening indication would represent the 
DMM's best understanding of the anticipated price of such security 
based on publicly-available information, such as research reports 
relating to that security. If that pre-opening indication does not 
attract

[[Page 6883]]

additional trading interest that can either trade or tighten the spread 
of the pre-opening indication, the DMM will not open the security.
    The Exchange proposes to provide more transparency regarding this 
process in the Pillar Auction Rules. As proposed, Rule 7.35A(b)(1) 
would provide that if a security has not previously traded on the 
Exchange, a DMM is not obligated to open such security if there is no 
bid or offer or if the best bid and offer is wider than the pre-opening 
indication. The Exchange believes that this proposed rule text would 
provide clarity as to why a new listed security may not open on the 
Exchange.
    DMM Opening Process. Proposed Rule 7.35A(c) would provide that a 
DMM may effectuate a Core Open or Trading Halt Auction manually or 
electronically (and if electronic, subject to Rule 104(b)(ii)). This 
proposed rule text is based on the first sentence of Rule 123D(a)(1)(B) 
with a non-substantive difference to use Pillar terminology to 
reference reopenings as well.
    Proposed Rule 7.35A(c)(1) would provide that except under the 
conditions of Rules 7.35A(c)(2) and (c)(3), a DMM may not effect a Core 
Open or Trading Halt Auction under the conditions specified in 
subparagraphs (A)-(H) of Rule 7.35A. This proposed rule text is based 
on the second sentence of Rule 123D(a)(1)(B) with non-substantive 
differences to use Pillar terminology. The Exchange believes that 
adding each of the following circumstances of when the DMM may not 
effect an opening or reopening electronically will promote transparency 
regarding the circumstances of when a DMM must open a security 
manually:
     If a pre-opening indication has been published for the 
Core Open Auction (see proposed Rule 7.35A(c)(1)(A)). This proposed 
rule text is new for the Pillar Auction Rules and represents current 
functionality. Currently, if the DMM publishes a pre-opening indication 
in a security, that security must be opened manually by the DMM.
     If a DMM has begun the process to open a security 
manually, including by manually entering DMM Auction Liquidity (see 
proposed Rule 7.35A(c)(1)(B)). This proposed rule text is based in part 
on Rule 123D(a)(1)(B), which provides that Exchange systems will not 
permit a DMM to open a security electronically if a DMM has manually 
entered Floor interest, which for purposes of that rule, includes 
manually entering DMM Interest. As described above, the DMM uses a 
graphical user interface to manage the opening process. From that user 
interface, the DMM can publish a pre-opening indication or enter DMM 
Auction Liquidity. The Exchange believes that if a DMM is in the 
process of using such graphical user interface, including to manually 
enter DMM Auction Liquidity or to publish a pre-opening indication, 
that DMM is taking an action to indicate that the opening or reopening 
process will be effectuated manually. Accordingly, if a DMM engages in 
such process, the Exchange will not permit the DMM to open or reopen 
the security electronically.
     If it is an IPO Auction or Direct Listing Auction (see 
proposed Rule 7.35A(c)(1)(C)). This proposed rule text is new for the 
Pillar Auction Rules and represents current functionality. Currently, 
DMMs effectuate both IPO Auctions and Direct Listing Auctions, which 
generally take place after 9:30 a.m., manually.
     If the security is in a suspended or halt condition at the 
beginning of Core Trading Hours (see proposed Rule 7.35A(c)(1)(D)). 
Because openings effectuated electronically take place at the beginning 
of Core Trading Hours, if a security is not eligible to be opened at 
such time because it is suspended or halted, such security would need 
to be opened by the DMM manually.
     If it is a reopening following a regulatory halt issued 
under Section 2 of the Listed Company Manual (see proposed Rule 
7.35A(c)(1)(E)). The Exchange believes that allowing a DMM to reopen a 
security electronically following either a trading pause or a market-
wide circuit breaker trading halt would promote the fair and orderly 
reopening of such security. This proposal is consistent with Rule 
15(e)(6)(B), which provides that the DMM may open a security following 
a trading pause outside of the published indication. By contrast, the 
Exchange believes that if a security is the subject of a regulatory 
halt issued under Section 2 of the Listed Company Manual, e.g., news 
pending, such reopening warrants the attention of the DMM assigned to 
that security, and therefore the reopening should be effectuated 
manually.
     If there is no Consolidated Last Sale Price (see proposed 
Rule 7.35A(c)(1)(F)). As described below, the Exchange proposes to use 
the Consolidated Last Sale Price as the Imbalance Reference Price for 
the Core Open and Trading Halt Auctions. The Exchange believes that if 
there is no Consolidated Last Sale Price in a security, the Exchange 
would not have sufficient information to provide to a DMM for opening a 
security electronically. Accordingly, the Exchange proposes that in 
such scenario, the DMM must open the security manually.
     If the Core Open or Trading Halt Auction Price would be 
more than 4% away from the Consolidated Last Sale Price (see proposed 
Rule 7.35A(c)(1)(G)). This proposed rule text is based on Rule 
123D(a)(1)(B)(i)(a) and (b), with the substantive difference, described 
above, that the Exchange would use the Consolidated Last Sale Price as 
the reference price for this calculation rather than the Official 
Closing Price (for openings) or last price on the Exchange (for 
reopenings). As noted above, the Exchange believes that using the 
Consolidated Last Sale Price, as defined in proposed Rule 
7.35(a)(11)(1), would likely reflect a more recent valuation in a 
security with which to measure whether the opening or reopening would 
be at a price disparity. The Exchange proposes to use the same 
percentage parameter as under the current rule.
     If the paired volume for the Core Open or Trading Halt 
Auction would be more than (i) 1,500 round lots for securities with an 
average opening volume of 1,000 round lots or fewer in the previous 
calendar quarter or (ii) 5,000 round lots for securities with an 
average opening volume of over 1,000 round lots in the previous 
calendar quarter (see proposed Rule 7.35A(c)(1)(H) and subparagraphs 
(i) and (ii)). This proposed rule text is based on Rule 
123D(a)(1)(B)(i)(c) with a non-substantive difference to use the term 
``paired volume'' instead of ``matched volume'' and use Pillar 
terminology. The Exchange also proposes a difference to reflect volumes 
in round lots rather than in number of shares. For securities that 
trade with a round lot of 100 shares, the proposed rule would be 
unchanged from the current rule, which expresses the volume 
requirements in terms of 150,000 shares, 100,000 shares, and 500,000 
shares, respectively. The Exchange believes, however, that if a 
security trades in a round lot less than 100 shares, expressing the 
volume in number of shares would result in higher relative requirements 
for such securities to be opened manually. The Exchange believes that 
describing volume requirements in round lots would better reflect the 
level of volumes of securities with lower-sized round lot units that 
would warrant an opening to be effected manually.
    Proposed Rule 7.35A(c)(2) would provide that if as of 9:00 a.m., 
the E-mini S&P 500 Futures are +/-2% from the prior day's closing price 
of the E-mini S&P 500 Futures, or if the

[[Page 6884]]

Exchange determines that it is necessary or appropriate for the 
maintenance of a fair and orderly market, a DMM may effect an opening 
or reopening electronically if the Auction Price would be up to 8% away 
from Consolidated Last Sale Price, without any volume limitations. This 
proposed rule text is based on Rule 123D(a)(1)(B)(ii) with non-
substantive differences to use Pillar terminology. The Exchange 
proposes a similar substantive difference, as described above, to use 
the Consolidated Last Sale Price as the reference price for determining 
the percentage parameter. Otherwise, this rule text is unchanged from 
the Current Auction Rules.
    Proposed Rule 7.35A(c)(3) would provide that when reopening a 
security following a trading pause under Rule 7.11 or a market-wide 
halt under Rule 7.12, if a pre-opening indication has been published in 
a security under paragraph (b) of this Rule, a DMM may not reopen such 
security electronically if the reopening transaction would be at a 
price outside of the last-published pre-opening indication. This 
proposed rule text is based on Rule 123D(a)(1)(B)(iii) with non-
substantive differences to cross-reference Pillar rules and use Pillar 
terminology. Otherwise, this rule text is unchanged from Current 
Auction Rules.
    Pre-Opening Indications. Proposed Rule 7.35A(d) and its 
subparagraphs are based on Rule 15(a)-(f) relating to pre-opening 
indications. Except for the few substantive differences described 
below, the Exchange does not propose any differences from the Current 
Auction Rules of when a pre-opening indication would be required.
    Proposed Rule 7.35A(d) would provide that a pre-opening indication 
would include the security and the price range within which the Auction 
Price is anticipated to occur and that a pre-opening indication would 
be published via the securities information processor and proprietary 
data feeds. This proposed rule text is based on Rule 15(a) with a non-
substantive difference to use the term ``Auction Price'' instead of 
``opening price.''
    Proposed Rule 7.35A(d)(1) would specify the conditions for 
publishing a pre-opening indication and is based on Rule 15(b).
     Proposed Rule 7.35A(d)(1)(A) would provide that a DMM 
would publish a pre-opening indication, as described in paragraph 
(d)(4) of this Rule, before a security opens or reopens if (i) the Core 
Open or Trading Halt Auction Price is anticipated to be a change of 
more than the ``Applicable Price Range,'' as specified in proposed Rule 
7.35A(d)(3), from a specified ``Indication Reference Price,'' as 
specified in proposed Rule 7.35A(d)(2), or (ii) it is a Delayed 
Opening. This proposed rule text is based on Rule 15(b)(1) with non-
substantive differences to use Pillar terminology, including reference 
to a Core Open or Trading Halt Auction Price, use of the new defined 
term ``Delayed Opening,'' and use of the term ``Indication Reference 
Price'' instead of ``Reference Price.'' The Exchange also proposes to 
reference reopens in addition to opens.\61\
---------------------------------------------------------------------------

    \61\ Supplementary Material .10 to Rule 15 provides that unless 
otherwise specified in Rule 15, references to an opening transaction 
include a reopening transaction following a trading halt or pause in 
a security. Rather than include that commentary in Rule 7.35A, the 
Exchange proposes that proposed rule text based on Rule 15 would be 
modified to reflect when such rule would be applicable to a 
reopening transaction.
---------------------------------------------------------------------------

     Proposed Rule 7.35A(d)(1)(B) would provide that when 
making the determination of what the Auction Price will be, the DMM 
will take into consideration all interest eligible to participate in 
the Core Open or Trading Halt Auction, including electronically-entered 
orders, and DMM Interest. This proposed rule text is based on Rule 
15(b)(2) with non-substantive differences to use Pillar terminology. On 
Pillar, the Exchange will not publish a pre-opening indication if the 
DMM is unable to do so because of systems or a technical issue. 
Accordingly, the Exchange does not propose to include in the Pillar 
Auction Rules rule text based on Rule 15(b)(3), which provides that if 
a DMM is unable to publish a pre-opening indication for one or more 
securities due to a systems or technical issue, the Exchange may 
publish a pre-opening indication for that security(ies).
    Proposed Rule 7.35A(d)(2) would address Indication Reference 
Prices, and is based on Rule 15(c), which refers to ``Reference 
Price.'' In the Pillar Auction Rules, the Exchange proposes to use the 
term ``Indication Reference Price'' in connection with pre-opening 
indications to distinguish it from the use of the term ``Imbalance 
Reference Price,'' described above.\62\
---------------------------------------------------------------------------

    \62\ The Indication Reference Price is not a publicly 
disseminated value, but rather a reference price used by the DMM to 
determine whether to publish a pre-opening indication. The actual 
pre-opening indication price range is based on the buy and sell 
orders in the Exchange Book, not on the Indication Reference Price.
---------------------------------------------------------------------------

    Proposed Rule 7.35A(d)(2)(A) would provide that the Indication 
Reference Price for a security, other than an American Depository 
Receipt (``ADR''), would be:
     The security's last Official Closing Price on the 
Exchange, adjusted as applicable based on the publicly disclosed terms 
of a corporate action (see proposed Rule 7.35A(d)(2)(A)(i)). This 
proposed rule text is based on Rule 15(c)(1)(A) without any 
differences.\63\
---------------------------------------------------------------------------

    \63\ The Exchange recently amended Rule 15(c)(1). See Securities 
Exchange Act Release No. 84755 (December 7, 2018), 83 FR 64168 
(December 13, 2018) (SR-NYSE-2018-60) (Notice of filing and 
immediate effectiveness of proposed rule change).
---------------------------------------------------------------------------

     The security's offering price in the case of an IPO (see 
proposed Rule 7.35A(d)(2)(A)(ii)). This proposed rule text is based on 
Rule 15(c)(1)(B) with non-substantive difference to use the defined 
term of IPO.
     The security's last reported sale price on the securities 
market from which the security is being transferred to the Exchange, on 
the security's first day of trading on the Exchange (``transferred 
security'') (see proposed Rule 7.35A(d)(2)(A)(iii)). This proposed rule 
text is based on Rule 15(c)(1)(C) without any differences.
     For a security that is a Direct Listing that has had 
recent sustained trading in a Private Placement Market prior to 
listing, the most recent transaction price in that market or, if none, 
a price determined by the Exchange in consultation with a financial 
advisor to the issuer of such security (see proposed Rule 
7.35A(d)(2)(A)(iv). This proposed rule text is based on Rule 
15(c)(1)(D) with non-substantive difference to use Pillar terminology, 
including the proposed defined term ``Direct Listing.''
     For a security that does not fall under proposed Rule 
7.35A(d)(2)(A)(i)-(iv) or (d)(2)(B) and for which there is limited 
publicly-available pricing available, a price as determined pursuant to 
proposed Rule 1.1(s)(1)(F). This proposed method of determining a 
derived last sale price is based in part on current Rule 123C(e)(i)(C), 
which specifies that when determining the Official Closing Price for a 
new listing that does not have any last-sale eligible trades on the 
Exchange on its first trading day, the Official Closing Price will be 
based on a derived last sale associated with the price of such security 
before it begins trading on the Exchange. For purposes of determining 
the Indication Reference Price for a pre-opening indication, proposed 
Rules 7.35A(d)(2)(A)(i)-(iv) and (B) identify known prices that can be 
used. However, there are circumstances when there is limited publicly-
available information about how a security should be priced, such as 
for a new listing that is a when-issued security or emerging from 
bankruptcy. In such case, the Exchange believes that the Indication 
Reference Price should be based on the price that is already

[[Page 6885]]

determined pursuant to proposed Rule 1.1(s)(1)(F).
    Proposed Rule 7.35A(d)(2)(B) would provide that the Indication 
Reference Price for an ADR would be:
     The closing price of the security underlying the ADR in 
the primary foreign market for such security when the trading day of 
the primary foreign market concludes after trading on the Exchange for 
the previous day has ended (see proposed Rule 7.35A(d)(2)(B)(i)). This 
proposed rule text is based on Rule 15(c)(2)(A) without any 
differences.
     Based on parity with the last sale price of the security 
underlying the ADR in the primary foreign market for such security when 
the trading day of the primary foreign market is open for trading at 
the time of the opening on the Exchange (see proposed Rule 
7.35A(d)(2)(B)(ii)). This proposed rule text is based on Rule 
15(c)(2)(B) without any differences.
    Proposed Rule 7.35A(d)(2)(C) would provide that the Indication 
Reference Price for reopening a security following a halt would be the 
Exchange Last Sale Price. This proposed rule text is based on Rule 
15(c)(2)(C) with a difference to use the Pillar term ``Exchange Last 
Sale Price'' rather than the term ``last reported sale price on the 
Exchange.'' In most circumstances, use of the term ``Exchange Last Sale 
Price'' would be the same as under the current rule's use of the term 
``last reported sale price.'' Where there could be divergence if the 
Official Closing Price is based on the last consolidated last-sale 
eligible price in a security, as proposed to be defined in Rule 1.1, 
described above. For the reasons discussed above of why the Exchange 
believes that this is an appropriate price to use for the Official 
Closing Price if there is no closing auction, the Exchange similarly 
believes that such price would be appropriate for using as the 
Indication Reference Price.
    Proposed Rule 7.35A(d)(3) would concern the Applicable Price Range, 
and is based on Rule 15(d) without any differences. Proposed Rule 
7.35A(d)(3)(A) would provide that except under the conditions set forth 
in proposed Rule 7.35A(d)(3)(B), the Applicable Price Range for 
determining whether to publish a pre-opening indication would be 5% for 
securities with an Indication Reference Price over $3.00 and $0.15 for 
securities with an Indication Reference Price equal to or lower than 
$3.00. This proposed rule text is based on Rule 15(d)(1) with non-
substantive differences to use Pillar terminology and to update the 
rule cross references.
    Proposed Rule 7.35A(d)(3)(B) would provide that if as of 9:00 a.m., 
the E-mini S&P 500 Futures are +/-2% from the prior day's closing price 
of the E-mini S&P 500 Futures, when reopening trading following a 
market-wide trading halt under Rule 7.12, or if the Exchange determines 
that it is necessary or appropriate for the maintenance of a fair and 
order market, the Applicable Price Range for determining whether to 
publish a pre-opening indication would be 10% for securities with an 
Indication Reference Price over $3.00 and $0.30 for securities with an 
Indication Reference Price equal to or lower than $3.00. This proposed 
rule text is based on Rule 15(d)(2) with non-substantive differences to 
use Pillar terminology and update the rule cross-reference.\64\
---------------------------------------------------------------------------

    \64\ As discussed below, the Exchange proposes to amend Rule 
7.12 to include rule text based on Rule 80B.
---------------------------------------------------------------------------

    Proposed Rule 7.35A(d)(4) would specify the procedures for 
publishing a pre-opening indication and that the DMM would use the 
procedures specified in subparagraphs (A)-(G) of that rule when 
publishing a pre-opening indication. This proposed rule text is based 
on Rule 15(e) without any differences.
     Proposed Rule 7.35A(d)(4)(A) would provide that 
publication of a pre-opening indication would require the supervision 
and approval of a Floor Governor. This proposed rule text is based on 
Rule 15(e)(1) without any differences.
     Proposed Rule 7.35A(d)(4)(B) would provide that a pre-
opening indication must be updated if the Core Open or Trading Halt 
Auction Price would be outside of a published pre-opening indication. 
This proposed rule text is based on Rule 15(e)(2) with a non-
substantive difference to use Pillar terminology.
     Proposed Rule 7.35A(d)(4)(C) would provide that if the 
pre-opening indication is a spread wider than $1.00, the DMM should 
undertake best efforts to publish an updated pre-opening indication of 
$1.00 or less before opening or reopening the security, as may be 
appropriate for the specific security. This proposed rule text is based 
on Rule 15(e)(3) with a non-substantive difference to reference 
reopenings in addition to openings.
     Proposed Rule 7.35A(d)(4)(D) would provide that after 
publishing a pre-opening indication, the DMM must wait for the 
following minimum specified periods before opening a security. This 
proposed rule text is based on Rule 15(e)(4) without any differences.
    [cir] Proposed Rule 7.35A(d)(4)(D)(i) would provide that when using 
the Applicable Price Range specified in Rule 7.35A(d)(3)(A), a minimum 
of three minutes must elapse between publication of the first 
indication and a security's opening or reopening. If more than one 
indication has been published, a security may be opened or reopened one 
minute after the last published indication provided that at least three 
minutes have elapsed from the dissemination of the first indication. 
However, the DMM may open or reopen a security less than the required 
minimum times after the publication of a pre-opening indication if the 
Auction Price would be at a price within the Applicable Price Range. 
This proposed rule text is based on Rule 15(e)(4)(A) with non-
substantive differences to update the rule cross reference, to include 
references to reopenings, and to use Pillar terminology.
    [cir] Proposed Rule 7.35A(d)(4)(D)(ii) would provide that when 
using the Applicable Price Range specified in Rule 7.35A(d)(3)(B), a 
minimum of one minute must elapse between publication of the first 
indication and a security's opening or reopening. If more than one 
indication has been published, a security may be opened or reopened 
without waiting any additional time. This proposed rule text is based 
on Rule 15(e)(4)(B) with non-substantive differences to update the rule 
cross reference and to include references to reopenings.
     Proposed Rule 7.35A(d)(4)(E) would provide that if trading 
is halted for a non-regulatory order imbalance, a pre-opening 
indication must be published as soon as practicable after the security 
is halted. This proposed rule text is based on Rule 15(e)(5) without 
any differences.
     Proposed Rule 7.35A(d)(4)(F) and subparagraphs (i)-(iii) 
would provide that when reopening a security following a trading pause 
under Rule 7.11: (i) A pre-opening indication may be published without 
prior Floor Governor approval; (ii) a pre-opening indication does not 
need to be updated before reopening the security, and the security may 
be reopened outside of any prior indication; and (iii) the reopening is 
not subject to the minimum waiting time requirements in Rule 
7.35A(d)(4)(D). This proposed rule text is based on Rule 15(e)(6) and 
subparagraphs (A)-(C) with a non-substantive difference to update the 
rule cross references.
     Proposed Rule 7.35A(d)(4)(G) would provide that except as 
provided in proposed Rule 7.35A(d)(4)(F)(ii), if a pre-opening 
indication has been

[[Page 6886]]

published, the Exchange would not permit the DMM to open or reopen the 
security outside of the last-published pre-opening indication range. 
This proposed rule text would be new for the Pillar Auction Rules and 
reflects that Exchange systems will enforce the requirement for a DMM 
to open or reopen a security within the price range of a pre-opening 
indication, except when reopening following a trading pause.
    As discussed below, the Exchange proposes to set forth the process 
for temporary rule suspensions in paragraph (j) to proposed Rule 7.35A. 
Accordingly, the Exchange does not propose to include rule text based 
on Rule 15(f) in paragraph (d) in Rule 7.35A.
    Auction Imbalance Information. Proposed Rule 7.35A(e) would specify 
Auction Imbalance Information for the Core Open and Trading Halt 
Auctions. Proposed Rule 7.35A(e)(1) would specify the time of 
publication of such Auction Imbalance Information as follows:
     Proposed Rule 7.35A(e)(1)(A) would provide that for the 
Core Open Auction, unless a security is halted, the Exchange would 
begin disseminating Auction Imbalance Information at 8:00 a.m. This 
proposed rule text is new and the Exchange proposes a substantive 
difference in the Pillar Auction Rules to begin disseminating Auction 
Imbalance Information at 8:00 a.m. rather than at 8:30 a.m., as 
specified in current Rule 15(g)(3)(A). The format of this rule text is 
based in part on NYSE Arca Rule 7.35-E(c)(1) and NYSE American Rule 
7.35E(c)(1).
     Proposed Rule 7.35A(e)(1)(B) would provide that for a 
Trading Halt Auction, the Exchange would begin disseminating Auction 
Imbalance Information at the beginning of a halt or pause. This 
proposed rule text represents current functionality and is based in 
part on Rule 80C(b), which provides that the Exchange will begin 
disseminating Order Imbalance Information after a Trading Pause has 
commenced. The format of this rule text is based in part on NYSE Arca 
Rule 7.35-E(e)(1) and NYSE American Rule 7.35E(e)(1).
     Proposed Rule 7.35A(e)(1)(C) would provide that if a 
security is in a halt condition before or at the beginning of Core 
Trading Hours, the Exchange would disseminate Auction Imbalance 
Information for a Trading Halt Auction. This proposed rule text would 
be new for the Pillar Auction Rules and is based on NYSE Arca Rule 
7.35-E(c)(1) and NYSE American Rule 7.35E(c)(1).
     Proposed Rule 7 .35A(e)(1)(D) would provide that the 
Exchange would not disseminate Auction Imbalance Information for the 
Core Open Auction or Trading Halt Auction if there is no Consolidated 
Last Sale Price. This proposed rule text would be new for the Pillar 
Auction Rules. Because, as described below, the Exchange would use the 
Consolidated Last Sale Price as the basis for determining the Imbalance 
Reference Price, if there is no Consolidated Last Sale Price, there 
would not be any information for the Exchange to determine Auction 
Imbalance Information.
    Proposed Rule 7.35A(e)(2) would specify the content of Auction 
Imbalance Information. As proposed, for the Core Open and Trading Halt 
Auctions, the Exchange would disseminate Total Imbalance, Side of Total 
Imbalance, Paired Quantity, and Continuous Book Clearing Price.
    Proposed Rule 7.35A(e)(3) would specify how the Imbalance Reference 
Price would be determined. As proposed, the Imbalance Reference Price 
for the Auction Imbalance Information would be the Consolidated Last 
Sale Price unless a pre-opening indication has been published. This 
proposed rule text would be new for Pillar Auction Rules and represents 
the proposed substantive difference that the Exchange would use the 
Consolidated Last Sale Price rather than last reported sale price on 
the Exchange, as provided for in Rule 15(g)(2)(B), for determining the 
Imbalance Reference Price for the Core Open and Trading Halt Auctions. 
The Exchange believes that use of the Consolidated Last Sale Price 
rather than the last reported sale price on the Exchange would allow 
for a more recent price in a security to be used as the Imbalance 
Reference Price, thereby representing a more recent valuation of such 
security.
    With the exception of using the Consolidated Last Sale Price rather 
than the last reported sale price on the Exchange, if a pre-opening 
indication has been published, the Exchange proposes to use the same 
method for determining the Imbalance Reference Price as under the 
Current Auction Rules. However, the Exchange proposes to use Pillar 
terminology to provide that in such case, the Imbalance Reference Price 
would be:
     The pre-opening indication bid price if the Consolidated 
Last Sale Price is lower than the bid price of the pre-opening 
indication (see proposed Rule 7.35A(e)(3)(A)). This is based in part on 
Rule 15(g)(2)(B)(i), which provides that if the bid price of the pre-
opening indication of interest is higher than the last reported sale 
price for the security on the Exchange, the pre-opening indication bid 
price will serve as the reference price.
     The pre-opening indication offer price if the Consolidated 
Last Sale Price is higher than the offer price of the pre-opening 
indication (see proposed Rule 7.35A(e)(3)(B)). This is based in part on 
Rule 15(g)(2)(B)(ii), which provides that if the offer price of the 
pre-opening indication of interest is lower than the last reported sale 
price for the security on the Exchange, the pre-opening indication 
offer price will serve as the reference price.
     The Consolidated Last Sale Price if it is at or between 
the pre-opening indication bid and offer price (see proposed Rule 
7.35A(e)(3)(C)). This is based in part on Rule 15(g)(2)(B)(iii), which 
provides that if the last reported sale price on the Exchange falls 
within the bid and offer of the pre-opening indication of interest for 
a security, the last sale price shall serve as the reference price. 
Because the term Consolidated Last Sale Price would incorporate how 
that price would be derived for a transferred security, the Exchange 
does not propose to include rule text based on Rule 15(g)(2)(B)(iv) in 
the Pillar Auction Rules.
    Auction Imbalance Freeze. Proposed Rule 7.35A(f) would provide that 
there is no Auction Imbalance Freeze for a Core Open Auction or Trading 
Halt Auction and no restrictions on entry or cancellation of Auction-
Only Orders before a Core Open Auction or Trading Halt Auction. This 
proposed rule text would be new for the Pillar Auction Rules and is 
based on current functionality as there are no restrictions on order 
entry or cancellation before the opening or reopening of trading under 
the Current Auction Rules. The Exchange believes that including this 
rule text in the Pillar Auction Rules would provide clarity and 
transparency to Exchange rules, particularly when comparing how 
auctions function on the Exchange as compared to NYSE Arca and NYSE 
American, which function differently.
    Determining an Auction Price. Proposed Rule 7.35A(g) would provide 
that the DMM would be responsible for determining the Auction Price for 
a Core Open Auction or a Trading Halt Auction. This proposed rule text 
would be new for the Pillar Auction rules and is based on current 
functionality that as part of the DMM's role in facilitating auctions, 
the DMM determines the Auction Price based on buy and sell orders 
represented in the Exchange Book. The Exchange believes that including 
this detail in Exchange rules

[[Page 6887]]

provides clarity and transparency to the Exchange's auction process.
    The rule would further provide that if there is an Imbalance of any 
size, the DMM must select an Auction Price at which all better-priced 
orders on the Side of the Imbalance can be satisfied. This proposed 
rule text is based in part on Rule 115A(a)(1), which specifies that 
market interest is guaranteed to participate in the opening or 
reopening transaction.\65\ Otherwise, this proposed rule text would be 
new for the Pillar Auction Rules, and is designed to promote clarity 
and transparency in Exchange rules relating to the Exchange's auction 
process.
---------------------------------------------------------------------------

    \65\ Under Rule 115A(a)(1)(A), market interest is defined as (i) 
Market and MOO Orders, (ii) limit interest to buy (sell) that is 
priced higher (lower) than the opening or reopening price, and (iii) 
Floor broker interest entered manually by the DMM. The first two of 
these categories are described above in the definition of better-
priced orders. The Exchange proposes that the DMM would not manually 
enter Floor broker interest for the Core Open or Trading Halt 
Auction; Floor brokers must represent their interest electronically.
---------------------------------------------------------------------------

    Proposed Rule 7.35A(g)(1) would further provide that when 
facilitating the opening on the first day of trading of a Direct 
Listing that has not had recent sustained history of trading in a 
Private Placement prior to listing, the DMM will consult with a 
financial advisor to the issuer of such security in order to effect a 
fair and orderly opening of such security. This proposed rule text is 
from the last sentence of Rule 104(a)(2) with a non-substantive 
difference to use the defined term of ``Direct Listing.'' The Exchange 
proposes to move this rule text from Rule 104 to proposed Rule 
7.35A(g)(1) because the responsibility described in the current rule 
relates to how an Auction Price is determined for a Direct Listing 
Auction, and the Exchange believes that including this text in proposed 
Rule 7.35A would consolidate requirements relating to the Exchange's 
auction process, thereby making the rules easier to navigate.\66\
---------------------------------------------------------------------------

    \66\ The Exchange proposes a related rule change to delete the 
last sentence of Rule 104(a)(2).
---------------------------------------------------------------------------

    Auction Allocation. Proposed Rule 7.35A(h) would specify how orders 
would be allocated in an Auction. As proposed, once an Auction Price 
has been determined, orders would be allocated in a Core Open Auction 
or Trading Halt Auction as follows:
     Better-priced orders, including the reserve interest of 
Reserve Orders, entered by the Book Participant or a Floor Broker 
Participant would be guaranteed to participate in the Auction at the 
Auction Price (see proposed Rule 7.35A(h)(1)). The Exchange proposes to 
use Pillar terminology in proposed Rule 7.35A(h)(1) to describe the 
same functionality as set forth in Rule 115A(a)(1) and Rule 
115A(a)(1)(A), which provides that market interest is guaranteed to 
participate in the opening or reopening transaction. Under Rule 
115A(a)(1), market interest includes the same types of orders defined 
in proposed Rules 7.35(a)(5)(A) and 7.35A(h)(1) as being guaranteed to 
participate in a Core Open or Trading Halt Auction.\67\
---------------------------------------------------------------------------

    \67\ Id.
---------------------------------------------------------------------------

     At-priced orders and DMM Interest of any price would not 
be guaranteed to participate in the Auction (see proposed Rule 
7.35A(h)(2)). The Exchange proposes to use Pillar terminology in 
proposed Rule 7.35A(h)(2) to describe the same functionality as set 
forth in Rules 115A(a)(1) and (a)(1)(B)-(C), including that DMM 
Interest is not guaranteed to participate in such Auctions. Proposed 
Rule 7.35A(h)(2) would further provide how at-priced orders would be 
allocated in an Auction as follows:
     First, orders ranked Priority 2--Display Orders, Opening D 
Orders, and LOO Orders would be allocated on parity by Participant 
pursuant to Rule 7.37(b)(2)--(7) (see proposed Rule 7.35A(h)(2)(A)). By 
cross-referencing Rule 7.37(b)(2)-(7), this proposed rule text makes 
clear that the allocation process for the Core Open Auction and Trading 
Halt Auction would follow the established Pillar parity allocation 
process.\68\ The Exchange believes that if at-priced Opening D Orders 
or LOO Orders are participating in the Core Open or Trading Halt 
Auction at the Auction Price, such orders should be allocated together 
with displayed orders, which is how such orders are allocated under the 
Current Auction Rules. In addition, by cross referencing Rules 
7.37(b)(5), (6), and (7), the proposed Rule provides specificity that 
allocations to each Participant, including the DMM, would be allocated 
consistent with those rules.
---------------------------------------------------------------------------

    \68\ See Securities Exchange Act Release No. 82945 (March 26, 
2018), 83 FR 13553, 13560-13561 (March 29, 2018) (SR-NYSE-2018-36) 
(Approval Order and discussion of how the Rule 7.37 Pillar parity 
allocation process differs from the current Rule 72 parity 
allocation process).
---------------------------------------------------------------------------

     Next, orders ranked Priority 3--Non-Display Orders would 
be allocated on parity by Participant pursuant to Rule 7.37(b)(2)-(7) 
(see proposed Rule 7.35A(h)(2)(B)). This proposed rule text would be 
applicable to the reserve interest of Reserve Orders, which are the 
only orders ranked Priority 3--Non-Display Orders eligible to 
participate in an Auction. By cross-referencing Rule 7.37(b)(2)--(7), 
this proposed rule text makes clear that the allocation process for the 
Core Open Auction and Trading Halt Auction will follow the established 
Pillar parity allocation process.
     Proposed Rule 7.35A(h)(3) would address the DMM 
Participant Allocation of at-priced orders in the Core Open and Trading 
Halt Auction. The Exchange proposes that the manner by which DMMs would 
participate in an Auction would differ from how they participate in 
allocations during continuous trading, described above. As proposed:
    [cir] At-priced DMM Orders would be placed on the allocation wheel 
for an Auction based on the time of entry and any other orders or 
interest from such DMM would join that position on the allocation wheel 
(see proposed Rule 7.35A(h)(3)(A)). In such case, the DMM Order with 
the earliest entry time would establish that DMM Participant's position 
on the allocation wheel, consistent with Rule 7.37(b)(2)(B).\69\ 
However, if the only DMM Interest available to participate in an 
Auction would be DMM Auction Liquidity or better-priced DMM Orders or 
both, such DMM Interest would be placed last on the allocation wheel. 
The Exchange proposes that in these scenarios, the DMM Interest would 
go last on the allocation wheel because such orders would either be 
repriced for the Auction (in the case of a better-priced DMM Order, 
which would be considered an at-priced order for the Auction 
Allocation) or entered right before the Auction (in the case of DMM 
Auction Liquidity). Because such DMM Interest is intended to be 
offsetting interest for an Auction, the Exchange does not believe that 
such DMM Interest should have time priority in how they are included in 
an allocation wheel over other orders that are eligible to participate 
in an Auction. This proposed functionality would be new on Pillar and 
is designed so that DMMs, who have the ability to enter buy and sell 
interest last in an Auction, would not receive any time priority for 
such interest.
---------------------------------------------------------------------------

    \69\ Rule 7.37(b)(2)(B) provides that additional Participants 
are added to an allocation wheel based on time of entry of the first 
order entered by a Participant.
---------------------------------------------------------------------------

    [cir] A parity allocation to the DMM Participant would be allocated 
in price-time priority (see proposed Rule 7.35A(h)(3)(B)). As discussed 
above, a parity allocation to the DMM Participant would be based on the 
working time. However, in an Auction Allocation, DMM Interest may have 
more than one limit price, and the Exchange proposes that the parity 
allocation to the DMM Participant would be allocated among

[[Page 6888]]

such DMM Interest in price-time priority, even though they all would 
participate in the Auction at a single price.
    [cir] Both at-priced DMM Orders that do not receive an allocation 
and that lock other unexecuted orders and buy and sell better-priced 
DMM Orders would be cancelled after the Auction Processing Period 
concludes (see proposed Rule 7.35A(h)(3)(C)). As noted above, DMM 
Auction Liquidity that does not participate in an Auction cancels after 
the Auction. To provide for continuity in the market after the Auction, 
the Exchange also proposes to cancel DMM Orders with a limit price that 
either lock the Auction Price, i.e., did not participate in the parity 
allocation, or are priced through the Auction Price, i.e., a buy (sell) 
DMM Order priced higher (lower) than the Auction Price. The Exchange 
believes that cancelling such DMM Interest would ensure that there will 
not be orders that transition to continuous trading that lock or cross 
other orders in the Exchange Book.
    SIP Modifier. Proposed Rule 7.35A(i) would provide that the Core 
Open Auction would be designated with a modifier to identify the 
opening quote, and if there is an opening trade, a modifier to identify 
the opening trade. The rule would further provide that the Trading Halt 
Auction would be designated with a modifier to identify it as a 
reopening trade. These SIP modifiers are consistent with how the 
Exchange functions under the Current Auction Rules and would be new 
rule text for the Pillar Auction Rules that is based on NYSE Arca Rule 
7.35-E(c)(5) and (e)(11) and NYSE American Rule 7.35E(c)(5) and 
(e)(11).
    Temporary Rule Suspensions. Current Rule 15(f) provides that the 
Exchange can temporarily suspend the requirement of pre-opening 
indications and current Rule 123D(c) provides that the Exchange can 
temporarily suspend DMM automated opening limitations or Floor Official 
approval requirements. In the Pillar Auction Rules, the Exchange 
proposes to consolidate these existing temporary suspension 
requirements in proposed Rule 7.35A(j).
    Proposed Rule 7.35A(j)(1) would provide that if the CEO of the 
Exchange, or his or her designee, determines that a Floor-wide event is 
likely to have an impact on the ability of DMMs to arrange for a fair 
and orderly Core Open or Trading Halt Auction at the Exchange and that, 
absent relief, the operation of the Exchange is likely to be impaired, 
the CEO of the Exchange, or his or her designees, may temporarily 
suspend the rules specified in proposed subparagraphs (A) and (B) of 
that Rule. This proposed rule text is based on Rule 15(f)(1) and Rule 
123D(c)(1) with non-substantive differences to use Pillar 
terminology.\70\
---------------------------------------------------------------------------

    \70\ Rule 123D(c)(1) currently provides that the temporary 
relief is available for a reopening following a market-wide circuit 
breaker. In harmonizing this rule text with current Rule 15(f)(1), 
the Exchange proposes that under the Pillar Auction Rules, the 
temporary rule suspension would be available for any scenario where 
a Floor-wide event would impact the fair and orderly reopening of 
securities, which include reopenings after a market-wide circuit 
breaker, plus other potential market-wide events.
---------------------------------------------------------------------------

    Proposed Rule 7.35A(j)(1)(A) would specify the first set of rules 
that could be suspended. As proposed, under the circumstances described 
above, the Exchange could suspend the prohibition on a DMM opening a 
security electronically if the Core Open or Trading Halt Auction Price 
would be more than the price or volume parameters specified in proposed 
Rule 7.35A(c)(1)(G) and (H) of this Rule. This proposed rule text is 
based on Rule 123D(c)(1)(A) with non-substantive differences to use 
Pillar terminology and update the cross references.\71\
---------------------------------------------------------------------------

    \71\ The Exchange does not propose to include in the Pillar 
Auction Rules a temporary suspension as described in Rule 
123D(c)(1)(B) because the Exchange no longer requires Floor Official 
approval before a security can be halted.
---------------------------------------------------------------------------

    Proposed Rule 7.35A(j)(1)(B) would specify the second set of rules 
that could be suspended. As proposed, under the circumstances described 
above, the Exchange could suspend the requirement to publish pre-
opening indications in a security under proposed Rule 7.35A(d) of this 
Rule prior to opening or reopening a security following a market-wide 
trading halt. This proposed rule text is based on Rule 15(f)(1) with 
non-substantive differences to update the cross reference.
    Proposed Rule 7.35A(j)(2) would provide that when determining 
whether to temporarily suspend the specified paragraphs of this Rule, 
the CEO of the Exchange would:
     Consider the facts and circumstances that are likely to 
have Floor-wide impact for a particular trading session, including 
volatility in the previous day's trading session, trading in foreign 
markets before the open, substantial activity in the futures market 
before the open, the volume of pre-opening indications of interest, 
evidence of pre-opening significant order imbalances across the market, 
government announcements, news and corporate events, and such other 
market conditions that could impact Floor-wide trading conditions (see 
proposed Rule 7.35A(j)(2)(A)). This proposed rule text is based on Rule 
15(f)(2)(A) and Rule 123D(c)(2)(A) without any substantive differences.
     Notify the Chief Regulatory Officer of the Exchange (see 
proposed Rule 7.35A(j)(2)(B)). This proposed rule text is based on Rule 
15(f)(2)(B) and Rule 123D(c)(2)(B) without any substantive differences.
     Inform the Securities and Exchange Commission staff as 
promptly as practicable of the temporary suspension (see proposed Rule 
7.35A(j)(2)(C)). This proposed rule text is based on Rule 15(f)(2)(C) 
and Rule 123D(c)(2)(C) without any substantive differences.
    Proposed Rule 7.35A(j)(3) would provide that a temporary suspension 
under this Rule would be in effect for the trading day on which it was 
declared only. This proposed rule text is based on Rule 15(f)(3) 
without any differences.
    Proposed Rule 7.35A(j)(4) would provide that notwithstanding a 
temporary suspension of the requirement to publish pre-opening 
indications in a security under this Rule, a DMM may publish a pre-
opening indication for one or more securities. This proposed rule text 
is based on Rule 15(f)(4) with a difference not to reference that the 
Exchange would publish a pre-opening indication. This proposed 
difference is based on the difference under the Pillar Auction Rules, 
described above, that the Exchange would not publish a pre-opening 
indication if a DMM is unable to do so.
Proposed Rule 7.35B (DMM-Facilitated Closing Auctions)
    Proposed Rule 7.35B would set forth the process for DMM-facilitated 
Closing Auctions. As described in greater detail below, to promote 
consistency and transparency in the Pillar Auction Rules, if the 
functionality described in proposed Rule 7.35B is the same as the 
functionality described in proposed Rule 7.35A, the Exchange proposes 
to use the same subparagraph numbering for the two rules. For example, 
Auction Imbalance Information for the Opening and Trading Halt Auctions 
will be described in proposed Rule 7.35A(e) and the Auction Imbalance 
Information for the Closing Auction will be described in proposed Rule 
7.35B(e). The Exchange believes that keeping these two rules as 
parallel as feasible would promote clarity, consistency, and 
transparency in Exchange rules.
    DMM and Floor Broker Responsibilities. Proposed Rule 7.35B(a) would 
set forth both the DMM and Floor broker responsibilities for the 
closing of securities. Similar to the DMM and Floor broker 
responsibilities as

[[Page 6889]]

described in proposed Rule 7.35A(a) above, DMMs and Floor brokers also 
have Floor-based roles in connection with the Closing Auction and the 
Exchange proposes to specify these requirements in proposed Rule 
7.35B(a).
    Proposed Rule 7.35B(a) would provide that it is the responsibility 
of each DMM to ensure that registered securities close as soon after 
the end of Core Trading Hours as possible, while at the same time not 
unduly hasty, particularly when at a price disparity from the Exchange 
Last Sale Price. This proposed rule would be new for the Pillar Auction 
Rules and reflects current DMM responsibilities, as specified in Rule 
104(a)(3), but with greater detail about how the DMM should facilitate 
the close of trading.
    The proposed rule text is based in part on the Rule 123D(a)(1) text 
relating to the opening of trading, which is proposed to be included in 
proposed Rule 7.35A(a) for the Pillar Auction Rules. The Exchange 
believes that because the DMM responsibilities for the Closing Auction 
are similar to the DMM responsibilities for the Core Open and Trading 
Halt Auctions, the Closing Auction Rule should have parallel rule text. 
A proposed difference for the Closing Auction version would be that the 
DMM should look at price disparity from the Exchange Last Sale Price 
when determining when to close the security. The proposed rule also 
makes clear the current functionality that the Closing Auction would 
occur after the end of Core Trading Hours, but that the DMM has a 
responsibility to ensure that registered securities close as soon after 
the end of Core Trading Hours as possible, but that it does not need to 
be unduly hasty if there is a price disparity.
    Proposed Rule 7.35B(a)(1) would specify how Floor Broker Interest 
would be entered for the Closing Auction. The functionality described 
in this proposed rule would be new for the Exchange. Currently, if a 
Floor broker orally represents a bid or offer at the point of sale 
before the close of trading, for such interest to be included in the 
closing transaction, the DMM must manually enter the details of the 
order on behalf of the Floor broker, including the security, side, 
size, limit price or if it is at market, and Floor broker badge number. 
The Exchange believes that in today's trading environment, this process 
introduces risk to the closing process because the DMM is responsible 
for both manually entering orders on behalf of potentially multiple 
Floor brokers in multiple securities and also facilitating the closing 
process for multiple securities. To reduce the burden on the DMM, the 
Exchange proposes that on Pillar, the Floor broker would be responsible 
for electronically entering interest that has been properly represented 
orally by the end of Core Trading Hours. While the DMM would still be 
responsible for validating such Floor broker-entered interest, the 
burden on the DMM would be minimized, which the Exchange believes would 
lead to a more efficient closing process.
    As proposed, Floor Broker Interest would be eligible to participate 
in the Closing Auction provided that the Floor broker has 
electronically entered such interest before the Auction Processing 
Period for the Closing Auction begins. Proposed Rule 7.35B(a)(1)(A) 
would provide that for such interest to be eligible to participate in 
the Closing Auction, a Floor broker must:
     First, by the end of, but not after, Core Trading Hours, 
orally represent Floor Broker Interest at the point of sale, including 
symbol, side, size, and limit price (see proposed Rule 
7.35B(a)(1)(A)(i)). This proposed rule text specifies the details of an 
order that a Floor broker must represent at the point of sale by the 
end of Core Trading Hours, e.g., not after 4:00 p.m. This rule text 
proposes a substantive difference from how Floor brokers can currently 
represent orders at the close because such orders would be required to 
include a limit price. Today, a Floor broker can represent an order at 
the close ``at market,'' which would not be supported on Pillar.
     Then, electronically enter such interest after the end of 
Core Trading Hours, and such electronic entry of Floor Broker Interest 
would not be subject to Limit Order Price Protection (see proposed Rule 
7.35B(a)(1)(A)(ii)). This proposed text would be new functionality for 
the Pillar Auction Rules and represents the proposed new method to 
electronically enter orally-represented Floor Broker Interest into 
Exchange systems for participation in the Closing Auction. To 
distinguish this interest from orders entered by a Floor broker during 
Core Trading Hours, the Exchange proposes that such interest could be 
entered only after the end of Core Trading Hours. In addition, because 
such interest would be eligible to participate in the Closing Auction 
only, the Exchange proposes that it would not be subject to Limit Order 
Price Protection, as described in Rule 7.31(a)(2)(B).
    Proposed Rule 7.35B(a)(1)(B) would provide that before Floor Broker 
Interest would be ranked for the Closing Auction, it must be 
electronically accepted by the DMM and that once accepted, Floor Broker 
Interest would be processed as an order ranked Priority 2--Display 
Orders from a Floor Broker Participant for purposes of inclusion in 
Closing Auction Imbalance Information and ranking and allocation in the 
Closing Auction. This proposed rule text would be new functionality for 
the Pillar Auction Rules and represents the more limited role that DMMs 
would have in processing Floor Broker Interest. The Exchange proposes 
that the DMM's electronic acceptance would serve to validate that the 
Floor broker had represented the Floor Broker Interest consistent with 
proposed Rule 7.35B(a)(1)(A).
    In addition, as described above, the Exchange proposes to continue 
disseminating Closing Auction Imbalance Information until the Auction 
begins. Pursuant to proposed Rule 7.35B(a)(1)(B), Floor Broker Interest 
would be included in such Closing Auction Imbalance Information after 
it has been accepted by the DMM. Because such Floor Broker Interest 
must include a limit price, the Exchange proposes to process it as an 
order ranked Priority 2--Display Orders for purposes of Auction 
Imbalance Information.
    In addition to the new functionality of including this interest in 
the Closing Auction Imbalance Information after 4:00 p.m., this 
proposed rule would represent new functionality of how Floor Broker 
Interest would be allocated in an Auction. Pursuant to Rule 
123C(7)(a)(iii), Floor broker interest entered manually by the DMM is 
considered ``has-to-go'' interest and is currently guaranteed to 
participate in the closing transaction. In Pillar, the Exchange 
proposes a difference that Floor Broker Interest would be ranked as 
Priority 2--Display Orders. Whether such Floor Broker Interest would be 
guaranteed to participate in the Closing Auction would be based on its 
limit price, which is consistent with how other orders ranked Priority 
2--Display Orders would be processed in the Closing Auction.\72\
---------------------------------------------------------------------------

    \72\ See discussion infra regarding proposed Rule 7.35B(h).
---------------------------------------------------------------------------

    Proposed Rule 7.35B(a)(1)(C) would provide that, after the end of 
Core Trading Hours, electronically-entered Floor Broker Interest could 
not be reduced in size or replaced, provided that, subject to Floor 
Official approval, a DMM can accept a full cancellation of 
electronically-entered Floor Broker Interest to correct a Legitimate 
Error. This proposed rule text would be new for the Pillar Auction 
Rules and represents current functionality that a Floor broker cannot 
change the terms of

[[Page 6890]]

an order after the close of Core Trading Hours. The Exchange believes, 
however, that if there is a Legitimate Error with the electronically-
entered order, the Floor broker should be able to cancel such order, 
but not replace it with a new order.\73\
---------------------------------------------------------------------------

    \73\ For example, if a Floor broker orally represents Floor 
Broker Interest to buy with a limit price of 10.02, but 
electronically enters it with a limit price of 100.2, the Floor 
broker should be able to fully cancel that order, but not replace 
it.
---------------------------------------------------------------------------

    Proposed Rule 7.35B(a)(2) would address DMM Interest and would 
provide that a DMM may enter or cancel DMM Interest after the end of 
Core Trading Hours in order to supply liquidity as needed to meet the 
DMM's obligation to facilitate the Closing Auction in a fair and 
orderly manner. This proposed rule text would be new for the Pillar 
Auction Rules and is based on the current Rule 104(a)(3) obligation for 
a DMM to supply liquidity as needed to facilitate the close of trading 
on the Exchange. Currently, the DMM can meet that obligation by 
entering or cancelling their own interest after 4:00 p.m. This proposed 
rule text would specify this functionality in the Pillar Auction Rules. 
Similar to Floor Broker Interest for the Closing Auction, the Exchange 
proposes that the entry of DMM Interest after the end of Core Trading 
Hours would not be subject to Limit Order Price Protection.
    Closing Without a Trade. Proposed Rule 7.35B(b) would provide that 
if there is no interest to conduct a Closing Auction, a DMM may close a 
registered security without a trade and that in such case, the Official 
Closing Price for the security would be determined as provided for in 
Rule 1.1. As noted above, if there is no interest to conduct a closing 
transaction, the DMM is not required to conduct a closing transaction 
or publish a new quote. However, even if there is no closing 
transaction, there would be an Official Closing Price disseminated for 
such security. This proposed rule text would be new for the Pillar 
Auction Rules and is designed to promote clarity and transparency 
regarding the Closing Auction process in Exchange rules.
    DMM Closing Process. Proposed Rule 7.35B(c) would provide that the 
DMM may effectuate a Closing Auction manually or electronically (see 
Rule 104(b)(ii)). This proposed rule text is based on Supplementary 
Material .10 to Rule 123C, which provides that closings may be 
effectuated manually or electronically (see Rule 104(b)). The Exchange 
proposes non-substantive differences to use Pillar terminology that 
mirrors proposed Rule 7.35A(c) relating to the DMM Opening Process.
    Supplementary Material to Rule 123C further provides that Exchange 
systems will not permit a DMM to close a security electronically if a 
DMM has manually-entered Floor interest. The Exchange believes that 
specifying the following circumstances when a DMM would not be 
permitted to effect a Closing Auction electronically to the Pillar 
Auction Rules will promote transparency regarding the circumstances of 
when a DMM must close a security manually:
     The DMM has begun the process to close a security 
manually, including by manually entering DMM Auction Liquidity (see 
proposed Rule 7.35B(c)(1)(A)). This proposed rule text is based in part 
on the second sentence of Supplementary Material .10 to Rule 123C, 
which provides that Exchange systems will not permit a DMM to close a 
security electronically if a DMM has manually-entered Floor interest, 
which includes manual DMM interest. The proposed rule text is also 
consistent with proposed Rule 7.35A(c)(1)(B), described above. 
Specifically, the DMM uses a graphical user interface to manage the 
closing process. From that template, the DMM can validate Floor Broker 
Interest or enter DMM Auction Liquidity. The Exchange believes that if 
a DMM is in the process of using such graphical user interface, 
including to manually enter DMM Auction Liquidity, the DMM is taking an 
action to indicate that the closing process will be effectuated 
manually. Accordingly, if a DMM engages in such process, the Exchange 
would not permit the DMM to close the security electronically.
     Floor Broker Interest for the Closing Auction that has 
been electronically entered or requested to be cancelled has not yet 
been accepted by the DMM (see proposed Rule 7.35B(c)(1)(B)). This 
proposed rule text would be new for Pillar Auction Rules and is related 
to the proposed new functionality relating to Floor Broker Interest for 
the Closing Auction pursuant to proposed Rule 7.35B(a)(1). The Exchange 
proposes that if a DMM has accepted all Floor Broker Interest that has 
been entered, the DMM can effectuate the closing electronically. 
However, if a Floor broker has entered Floor Broker Interest or 
requested to cancel such interest, but the DMM has not yet accepted the 
instruction, the Exchange would not permit the DMM to effectuate the 
closing electronically.
     It is the first day of trading of a security that is the 
subject of an IPO or a Direct Listing and the security never opened 
(see proposed Rule 7.35B(c)(1)(C)). This proposed rule text would be 
new for Pillar Auction Rules and would specify how the DMM should 
process a security that is the subject of an IPO or a Direct Listing 
and never opened. In such case, the Exchange does not believe that the 
closing should be effectuated electronically.\74\
---------------------------------------------------------------------------

    \74\ Because the Exchange accepts Auction-Only Orders intended 
for the Closing Auction beginning at 6:30 a.m., it is possible for a 
security to never open, and yet have interest that is eligible for a 
Closing Auction and that could trade. The Exchange does not believe 
that the DMM should electronically effect such a closing. Rather, in 
such rare circumstances, the Exchange believes that the DMM should 
manage such closing process manually.
---------------------------------------------------------------------------

     The security is suspended or halted at the end of Core 
Trading Hours (see proposed Rule 7.35B(c)(1)(D)). This proposed rule 
text would be new for Pillar Auction Rules and is based on current 
functionality. The Exchange believes that if a security is halted or 
suspended at the end of Core Trading Hours, a DMM should not be 
permitted to effectuate a closing electronically because such security 
may still be suspended or halted when the DMM attempts to conduct such 
closing electronically. If the suspension or halt state is lifted 
shortly after 4:00 p.m., the Exchange believes that if there is 
interest to conduct a Closing Auction, the DMM should facilitate that 
closing process manually.
     There is no Exchange Last Sale Price (see proposed Rule 
7.35B(c)(1)(E)). This proposed rule text would be new for Pillar 
Auction Rules and is based on current functionality. As described 
below, the Exchange proposes to use the Exchange Last Sale Price as the 
Imbalance Reference Price for the Closing Auction. The Exchange 
believes that if there is no Exchange Last Sale Price in a security, 
the Exchange would not have sufficient information to provide to a DMM 
for closing a security electronically. Accordingly, the Exchange 
proposes that in such scenario, the DMM must close the security 
manually.
     A temporary suspension under proposed Rule 7.35B(j)(2)(A) 
of this Rule has been invoked (see proposed Rule 7.35B(c)(1)(F)). This 
proposed rule text would be new for the Pillar Auction Rules and 
reflects that if Rule 7.34(a)(2)(B) has been suspended pursuant to 
proposed Rule 7.35B(j)(2)(A) to permit the solicitation and entry of 
orders after the end of Core Trading Hours because of extreme order 
imbalances at or near the close, the Exchange believes that such 
closing should be effectuated manually.
     The Closing Auction Price would be more than a designated 
percentage away from the Exchange Last Sale Price (see proposed Rule 
7.35B(c)(1)(G)). This

[[Page 6891]]

proposed rule text would be new for the Pillar Auction Rules and 
represents current functionality of when the DMM is not permitted to 
effectuate a closing electronically. Similar to how current Rule 
123D(a)(1)(B)(i)(a) and (b) function for the open, today, the Exchange 
does not permit the DMM to effectuate a closing electronically if the 
DMM were to close a security a designated percentage away from the last 
sale price on the Exchange. In the Pillar Auction Rules, the Exchange 
proposes to specify this limitation.
    As proposed, the Exchange would use the Exchange Last Sale Price as 
the reference price for determining whether the Closing Auction Price 
would be at a price disparity requiring a manual closing process. The 
Exchange further proposes that if the Exchange Last Sale Price were 
$25.00 and below, the designated percentage would be 5%, if the 
Exchange Last Sale Price were $25.01 to $50.00, the designated 
percentage would be 4%, and if the Exchange Last Sale Price were above 
$50.00, the designated percentage would be 2%. These are the current 
designated percentages that the Exchange uses to determine whether to 
permit a DMM to effectuate a closing electronically. The Exchange 
believes that if a Closing Auction Price were to be outside these 
proposed designated percentages, the closing process should be effected 
manually.
     The paired volume for the Closing Auction would be more 
than 1,000 round lots for such security (see proposed Rule 
7.35B(c)(1)(H)). This proposed rule text would be new for the Pillar 
Auction Rules and represents current functionality of when the DMM is 
not permitted to effectuate a closing electronically. Similar to 
current Rule 123D(a)(1)(B)(i)(c) and proposed Rule 7.35A(c)(1)(H) for 
the opens and reopens, the Exchange proposes that the close should not 
be effectuated electronically if the volume would exceed specified 
parameters. Today, the Exchange does not permit a closing transaction 
if it would be over 100,000 shares in size. In the Pillar Auction 
Rules, the Exchange proposes to specify this requirement in round lots.
    Closing Imbalance. Proposed Rule 7.35B(d) would specify the 
requirements relating to Closing Imbalances, and is based on Rules 
123C(1)(b), (1)(d), (4) and (5).
    Proposed Rule 7.35B(d) would specify that a Closing Imbalance 
publication would include the Imbalance and the Side of the Imbalance. 
This proposed rule text is based in part on Rule 123C(4), which 
describes how the buy or sell side imbalance is determined. The 
proposed rule would also provide that the Imbalance Reference Price for 
a Closing Imbalance would be the Exchange Last Sale Price. This 
proposed rule text is based in part on Rule 123C(4)(a)(i) and (ii), 
which specifies that the last sale in a security, as reported to the 
Consolidated Tape, would be the reference price. The Exchange proposes 
a substantive difference on Pillar to use the Exchange Last Sale Price, 
as defined in proposed Rule 7.35(a)(11)(B) above. As noted above, and 
as described below, the Exchange proposes to use the Exchange Last Sale 
Price for any scenario relating to the Closing Auction that would need 
a reference price, including as the reference price for determining 
price disparity to permit a DMM to close a security electronically or 
as the Imbalance Reference Price for Auction Imbalance Information. The 
Exchange believes it would promote consistency in Exchange rules to use 
the same price for all of these purposes.
    As a corollary, the Exchange proposes that it would not disseminate 
a Closing Imbalance if there is no Exchange Last Sale Price. This would 
be new rule text for the Pillar Auction Rules and reflects that if 
there is no sale information for a security, the Exchange would not be 
able to calculate an imbalance, and therefore would not be able to 
assess whether to publish a Closing Imbalance. Finally, proposed Rule 
7.35B(d) would provide that a Closing Imbalance would be disseminated 
to the securities information processor and that a Regulatory Closing 
Imbalance would also be disseminated to proprietary data feeds. This 
proposed rule text represents current functionality and is based in 
part on Rules 123C(5)(a) and (b), which provides that both the 
Mandatory MOC/LOC Imbalance Publication and Informational Imbalance 
Publication are published on the Consolidated Tape. This proposed rule 
text is also based in part on Rule 123C(6)(a)(vi), which references the 
Mandatory MOC/LOC Imbalance Publication as part of the Order Imbalance 
Information.
    Proposed Rule 7.35B(d)(1) would specify the requirements for 
publication of a Regulatory Closing Imbalance. As proposed, at the 
Closing Auction Imbalance Freeze Time (as defined above in proposed 
Rule 7.35(a)(7)), if the Closing Imbalance is 500 round lots or more, 
the Exchange would disseminate a Regulatory Closing Imbalance. This 
proposed rule text is based on Rule 123C(1)(d)(i) and the first 
sentence of Rule 123C(5)(a) with non-substantive difference to use 
Pillar terminology and a substantive difference to use round lots 
rather than the current rule, which requires the imbalance amount to be 
50,000 shares. The Exchange believes that using round lots would better 
reflect the significance of the imbalance, particularly for securities 
with a round-lot size under 100 shares.
    Proposed Rule 7.35B(d)(1)(A) would provide that if, at the Closing 
Auction Imbalance Freeze Time, the Closing Imbalance is less than 500 
round lots, but is otherwise significant in relation to the average 
daily trading volume in the security, a DMM may disseminate a 
Regulatory Closing Imbalance only with prior Floor Official approval. 
This proposed rule text is based on the second sentence of Rule 
123C(5)(a) with non-substantive differences to use Pillar terminology 
and a substantive difference to use round lots rather than refer to the 
imbalance size in shares.
    Proposed Rule 7.35B(d)(1)(B) would provide that a Regulatory 
Closing Imbalance would be a one-time publication that should not be 
updated. This proposed rule text is based on Rule 123C(5)(A), which 
states that the Regulatory Closing Imbalance is published as soon as 
practicable after 3:50 p.m. This proposed rule text distinguishes the 
Regulatory Closing Imbalance from the Auction Imbalance Information, 
which would be updated every second.
    Proposed Rule 7.35B(d)(1)(C) would provide that a Regulatory 
Closing Imbalance would be disseminated at the Closing Auction 
Imbalance Freeze Time regardless of whether the security has not opened 
or is halted or paused at that time. This proposed rule text is based 
in part on Rule 123C(5)(c) with non-substantive differences to use 
Pillar terminology. The Exchange also proposes a substantive difference 
because under Current Auction Rules, when a trading halt in a security 
is in effect at 3:50 p.m. but is lifted prior to the close of trading 
in the security, a Mandatory MOC/LOC Imbalance Publication should be 
published as close to the resumption of trading as practicable. By 
contrast, under the Pillar Auction Rules, the Exchange proposes to 
publish a Regulatory Closing Imbalance at the Closing Auction Imbalance 
Freeze Time regardless of whether a security has not opened or is 
halted or paused at that time.
    Proposed Rule 7.35B(d)(2) would specify the requirements for 
publication of a Manual Closing Imbalance. As proposed, beginning one 
hour before the scheduled end of Core Trading Hours up to the Closing 
Auction Imbalance Freeze Time, a DMM may disseminate a Manual Closing 
Imbalance only with prior Floor Official approval and only a

[[Page 6892]]

DMM can update a Manual Closing Imbalance publication. This proposed 
rule text is based in part on current Rule 123C(1)(b) that an 
Informational Imbalance Publication can only be between 3:00 p.m. and 
3:50 p.m., and on Rule 123C(5)(b), which provides that an Informational 
Imbalance Publication may be published between 3:00 and 3:50 p.m. with 
the prior approval of a Floor Official, with non-substantive 
differences to use Pillar terminology.\75\
---------------------------------------------------------------------------

    \75\ Rule 123C(5)(b) also refers to a qualified ICE employee as 
defined in NYSE Rule 46.10. Rule 46(b)(v) provides that qualified 
ICE employees may be designated as a Floor Governor, and pursuant to 
Rule 46(b)(ii), a Floor Governor is also deemed to be a Floor 
Official. Accordingly, the Exchange believes that separately 
referencing qualified ICE employees would be redundant of simply 
referring to Floor Officials and therefore does not propose to 
reference qualified ICE employees as defined in NYSE Rule 46.10 in 
proposed Rule 7.35B(d)(2).
---------------------------------------------------------------------------

    Proposed Rule 7.35B(d)(2)(A) would provide that if a DMM 
disseminates a Manual Closing Imbalance before the Closing Auction 
Imbalance Freeze Time, such publication must be updated at the Closing 
Auction Imbalance Freeze Time with either: (i) A Regulatory Closing 
Imbalance, if the conditions specified in proposed Rule 7.35B(d)(1) are 
met; or (ii) a ``No Imbalance'' publication if the conditions specified 
in proposed Rule 7.35B(d)(1) are not met. This proposed rule text is 
based on Rule 123C(5)(b)(i) and (ii) with non-substantive differences 
to use Pillar terminology.
    Auction Imbalance Information. Proposed Rule 7.35B(e) would specify 
Auction Imbalance Information for the Closing Auction. Proposed Rule 
7.35B(e)(1) would specify the time of publication of such Auction 
Imbalance Information as follows:
     Proposed Rule 7.35B(e)(1)(A) would provide that for the 
Closing Auction, the Exchange would begin disseminating Auction 
Imbalance Information at the Closing Auction Imbalance Freeze Time even 
if such security is in a halt condition or has not yet opened. This 
proposed rule text is based in part on Rule 123C(1)(f), which defines 
the time when the Exchange begins publishing Order Imbalance 
Information, and Rule 123C(6)(a) with non-substantive differences to 
use Pillar terminology.
     Proposed Rule 7.35B(e)(1)(B) would provide that beginning 
two hours before the end of Core Trading Hours up to the Closing 
Auction Imbalance Freeze Time, the Exchange would make available Total 
Imbalance, Side of Total Imbalance, Paired Quantity, Unpaired Quantity, 
Side of Unpaired Quantity, and if published, Manual Closing Imbalance, 
to Floor brokers for any security (i) in which a Floor broker has 
entered an order or (ii) as specifically requested by a Floor broker 
and that this Auction Imbalance Information would be provided in a 
manner that does not permit electronic redistribution. The rule would 
further provide that beginning at the Closing Auction Imbalance Freeze 
Time, all Closing Auction Imbalance Information would be made available 
to Floor brokers. This proposed rule text is based on Rule 123C(6)(b) 
with non-substantive differences to use Pillar terminology.
     Proposed Rule 7.35B(e)(1)(C) would provide that the 
Exchange would not disseminate Auction Imbalance Information for the 
Closing Auction if there is no Exchange Last Sale Price. This proposed 
rule text would be new for the Pillar Auction Rules based on current 
functionality. Because, as described below, the Exchange would use the 
Exchange Last Sale Price as the basis for determining the Imbalance 
Reference Price, if there is no Exchange Last Sale Price, there would 
not be any information for the Exchange to determine Auction Imbalance 
Information.
    Proposed Rule 7.35B(e)(2) would specify the content of Auction 
Imbalance Information. As proposed, the Closing Auction Imbalance 
Information would include Total Imbalance, Side of Total Imbalance, 
Paired Quantity, Unpaired Quantity, Side of Unpaired Quantity, 
Continuous Book Clearing Price, Closing Interest Only Clearing Price, 
and Regulatory Closing Imbalance. This proposed rule text is based on 
Rule 123C(6)(a)(i), which describes the Order Imbalance Information 
disseminated under the Current Auction Rules, with non-substantive 
differences to use Pillar terminology. In addition, as described above, 
including Unpaired Quantity and Side of Unpaired Quantity would be new 
information included under the Pillar Auction Rules.
    Proposed Rule 7.35A(e)(3) would specify how the Imbalance Reference 
Price for the Closing Auction would be determined. As proposed, the 
Imbalance Reference Price for the Auction Imbalance Information would 
be:
     The BB if the Exchange Last Sale Price is lower than the 
BB (see proposed Rule 7.35B(e)(3)(A)).
     The BO if the Exchange Last Sale Price is higher than the 
BO (see proposed Rule 7.35B(e)(3)(B)).
     The Exchange Last Sale Price if it is at or between the 
BBO or if the security was halted or not opened by the Closing Auction 
Imbalance Freeze Time (see proposed Rule 7.35B(e)(3)(C)).\76\
---------------------------------------------------------------------------

    \76\ The terms BB, BO, and BBO are defined in Rule 1.1 to mean 
the best bid on the Exchange, the best offer on the Exchange, and 
the best bid or offer on the Exchange, respectively.
---------------------------------------------------------------------------

    This proposed rule text is based on Rule 123C(6)(a)(iii) and 
subparagraphs (A)-(C) with non-substantive differences to use Pillar 
terminology and a substantive difference to use Exchange Last Sale 
Price rather than the last sale price of such security on the Exchange. 
If a security has traded that day on the Exchange, use of the term 
``Exchange Last Sale Price'' would have the same meaning as the current 
rule. However, if there were no trades that day in a security on the 
Exchange and the prior day's Official Closing Price were based on a 
consolidated last-sale eligible trade from another exchange, then use 
of the term Exchange Last Sale Price would have a substantive 
difference from use of the term ``last sale price'' under current Rule 
123C(6)(a)(iii). The Exchange believes that in such scenario, the term 
Exchange Last Sale Price may have a more recent valuation than use of 
the term last sale price on the Exchange.
    Auction Imbalance Freeze. Proposed Rule 7.35B(f) would provide that 
the Auction Imbalance Freeze for the Closing Auction would begin at the 
Closing Auction Imbalance Freeze Time. This proposed rule text is based 
on Rules 123C(2), (3), (4), (5) and (6), which each reference the 3:50 
p.m. time as the beginning of order entry and cancellation restrictions 
and when the Exchange will begin disseminating information about the 
close. The Exchange proposes non-substantive differences to use Pillar 
terminology.
    Proposed Rule 7.35B(f) would further provide that order entry and 
cancellation would be processed during the Closing Auction Imbalance 
Freeze as follows:
     Entry of MOC and LOC Orders (proposed Rule 7.35B(f)(1)).
    [cir] Proposed Rule 7.35B(f)(1)(A) would provide that if a 
Regulatory Closing Imbalance has not been published, the Exchange would 
reject all MOC and LOC Orders and requests to cancel and replace MOC 
and LOC Orders that would result in a new MOC or LOC Order. This 
proposed rule text is based on Rule 123C(2)(b)(ii) with non-substantive 
differences to use Pillar terminology.
    [cir] Proposed Rule 7.35B(f)(1)(B) would provide that if a 
Regulatory Closing Imbalance has been published, the Exchange would 
accept MOC and LOC Orders opposite to the Side of the Regulatory 
Closing Imbalance and would reject MOC and LOC Orders on the Side of 
the Imbalance and requests to cancel and replace MOC and LOC

[[Page 6893]]

Orders that would result in a new MOC or LOC Order on the Side of the 
Imbalance. This proposed rule text is based on Rule 123C(2)(b)(i) with 
non-substantive differences to use Pillar terminology.\77\
---------------------------------------------------------------------------

    \77\ The Exchange does not propose rule text in the Pillar 
Auction Rules based on Rule 123C(2)(a), which describes MOC and LOC 
Order entry before 3:50 p.m., or 123C(2)(b)(3), which describes CO 
Order entry after 3:50 p.m. Under the Pillar Auction Rules, the 
Exchange proposes to describe only when order entry is restricted. 
The Exchange also does not propose rule text based on Rule 
123C(2)(c), which describes order entry in the event of a Trading 
Halt. As described above, the Exchange would disseminate a 
Regulatory Closing Imbalance at the Closing Auction Imbalance Freeze 
Time even if a security were halted or paused at that time. 
Accordingly, order entry of MOC and LOC Orders during such period 
would need to comply with proposed Rule 7.35B(f)(1)(A) and (B) 
regardless of whether a security is halted or paused.
---------------------------------------------------------------------------

     Cancellation of MOC, LOC, and Closing IO Orders (see 
proposed Rule 7.35B(f)(2)).
    [cir] Proposed Rule 7.35B(f)(2)(A) would provide that from the 
beginning of the Auction Imbalance Freeze Time until two minutes before 
the scheduled end of Core Trading Hours, MOC, LOC, and Closing IO 
Orders may be cancelled or reduced in size only to correct a Legitimate 
Error. This proposed rule text is based on Rule 123C(3)(b) with non-
substantive differences to use Pillar terminology.\78\
---------------------------------------------------------------------------

    \78\ The Exchange does not propose rule text based on Rule 
123C(3)(a), which provides that MOC, LOC and CO orders may be 
cancelled or reduced in size for any reason up to 3:50 p.m. Under 
the Pillar Auction Rules, the Exchange proposes to describe only 
when order cancellation would be restricted.
---------------------------------------------------------------------------

    [cir] Proposed Rule 7.35B(f)(2)(B) would provide that except as 
provided for in proposed Rule 7.35B(j)(2)(B) of this Rule, a request to 
cancel, cancel and replace, or reduce in size a MOC, LOC, or Closing IO 
Order entered two minutes or less before the scheduled end of Core 
Trading Hours would be rejected. This proposed rule text is based on 
Rule 123C(3)(c) with non-substantive differences to use Pillar 
terminology and update the rule cross-references.
     Proposed Rule 7.35B(f)(3) would provide that beginning 10 
seconds before the scheduled close of trading, a request to enter a 
Closing D Order in any security, cancel and replace a Closing D Order 
in any security that would result in a new Closing D Order, or cancel, 
cancel and replace, or modify a Closing D Order in an Auction-Eligible 
Security would be rejected. The proposed rule text relating to 
restrictions on the entry of Closing D Orders in any security is based 
in part on the operation of d-Quotes for Exchange-listed securities 
described in the second sentence of current Rule 70.25(a)(ii), which 
prohibits the entry of d-Quotes 10 seconds or less before the close of 
trading. Similarly, the Exchange proposes that a request to cancel and 
replace a Closing D Order that would result in a new Closing D Order 
would similarly be rejected because it would result in the entry of a 
new Closing D Order. Because the Exchange would accept a Closing D 
Order in a UTP Security, even though such order would be routed to the 
primary market, as proposed, such orders would also be rejected if 
entered 10 seconds or less before the scheduled close of trading.
    The Exchange further proposes that requests to cancel, cancel and 
replace, or modify Closing D Orders during this same period should also 
be rejected, which would be new functionality on Pillar. Because this 
is new functionality, it would be applicable only to Closing D Orders 
in Auction-Eligible Securities. The Exchange does not propose the same 
restriction for Closing D Orders in UTP Securities because such 
securities are routed to the applicable primary listing market as 
either a MOC or LOC Order, and would be processed by the primary 
listing market under its applicable rules.
     Proposed Rule 7.35B(f)(4) would provide that all other 
order instructions would be accepted, subject to the terms of such 
orders. This proposed rule text is based in part on NYSE Arca Rule 
7.35-E(d)(2)(C) and NYSE American Rule 7.35E(d)(2)(C) and reflects the 
Pillar terminology to specify only restrictions on entry and 
cancellation of orders.
    Determining an Auction Price. Proposed Rule 7.35B(g) would provide 
that the DMM would be responsible for determining the Auction Price for 
a Closing Auction under this Rule. This proposed rule text would be new 
for the Pillar Auction rules and is based on current functionality that 
as part of the DMM's role in facilitating auctions, the DMM determines 
the Auction Price based on buy and sell orders represented in the 
Exchange Book. The Exchange believes that including this detail in 
Exchange rules provides clarity and transparency to the Exchange's 
auction process.
    The rule would further provide that if there is an Imbalance of any 
size, the DMM must select an Auction Price at which all better-priced 
orders on the Side of the Imbalance can be satisfied. This proposed 
rule text is based in part on Rule 123C(8)(a)(i)(A), which specifies 
that Market Orders and Limit Orders better priced than the closing 
price trading against the imbalance amount are guaranteed to 
participate in the closing transaction.\79\ Otherwise, this proposed 
rule text would be new for the Pillar Auction Rules, and is designed to 
promote clarity and transparency in Exchange rules relating to the 
Exchange's auction process.
---------------------------------------------------------------------------

    \79\ In the Pillar Auction Rules, a Market Order that is held 
unexecuted pursuant to Rule 7.31(a)(1)(A) would be considered 
better-priced interest when it is included for allocation in an 
Auction.
---------------------------------------------------------------------------

    Auction Allocation. Proposed Rule 7.35B(h) would specify how orders 
would be allocated in an Auction. As proposed, once an Auction Price 
has been determined, orders would be allocated in a Closing Auction as 
follows:
     Better-priced orders, including the reserve interest of 
Reserve Orders, entered by the Book Participant or a Floor Broker 
Participant would be guaranteed to participate in the Closing Auction 
at the Auction Price (see proposed Rule 7.35B(h)(1)). The Exchange 
proposes to use Pillar terminology in proposed Rule 7.35B(h)(1) to 
describe the same functionality as set forth in Rule 123C(7), which 
specifies the orders that must be executed in whole or in part in the 
closing transaction, i.e., are better-priced orders.
     At-priced orders and DMM Interest of any price would not 
be guaranteed to participate in the Closing Auction (see proposed Rule 
7.35B(h)(2)). The Exchange proposes to use Pillar terminology in 
proposed Rule 7.35B(h)(2) to describe the functionality as set forth in 
Rule 123C(7)(b), including that DMM Interest is not guaranteed to 
participate in such Auctions. Proposed Rule 7.35B(h)(2) would further 
provide how at-priced orders would be allocated in an Auction as 
follows:
    [cir] First, orders ranked Priority 2--Display Orders and Closing D 
Orders would be allocated on parity by Participant pursuant to Rule 
7.37(b)(2)-(7) (see proposed Rule 7.35B(h)(2)(A)). By cross-referencing 
Rule 7.37(b)(2)-(7), this proposed rule text makes clear that the 
allocation process for the Closing Auction would follow the established 
Pillar parity allocation process. The Exchange believes that if at-
priced Closing D Orders are participating in the Closing Auction at the 
Auction Price, such orders should be allocated together with displayed 
orders. In addition, by cross referencing Rules 7.37(b)(5), (6), and 
(7), the proposed Rule provides specificity that allocations to each 
Participant, including DMMs, would be allocated consistent with those 
rules.
    [cir] Next, orders ranked Priority 3--Non-Display Orders would be 
allocated on parity by Participant pursuant to

[[Page 6894]]

Rule 7.37(b)(2)-(7) (see proposed Rule 7.35B(h)(2)(B)). This proposed 
rule text would be applicable to the reserve interest of Reserve 
Orders, which are the only orders ranked Priority 3--Non-Display Orders 
eligible to participate in an Auction. By cross-referencing Rule 
7.37(b)(2)-(7), this proposed rule text makes clear that the allocation 
process for the Closing Auction would follow the established Pillar 
parity allocation process.
    [cir] Next, LOC Orders would be allocated on time (see proposed 
Rule 7.35B(h)(2)(C)). This proposed allocation would be new under the 
Pillar Auction Rules. Unlike LOO Orders, which are displayed at their 
limit price prior to the Core Open or Trading Halt Auction, LOC Orders 
are not displayed at their limit price. LOC Orders are included in the 
aggregate in Auction Imbalance Information only to determine the 
Imbalance. Because they are not displayed, the Exchange does not 
believe that they should be ranked together with orders ranked Priority 
2--Display Orders. The Exchange further believes that orders ranked 
Priority 3--Non-Displayed Orders should have priority over LOC Orders 
because such orders were eligible to trade before the Closing Auction, 
and therefore were at risk of trading before the Auction.
    [cir] Next, Closing IO Orders opposite to the Side of the Unpaired 
Quantity would be allocated on time (see proposed Rule 7.35B(h)(2)(D)). 
This proposed rule text is based on Rule 13(c)(1), which describes how 
CO Orders are allocated. The Exchange proposes non-substantive 
differences to use Pillar terminology to describe the same 
functionality. Proposed Rule 7.35B(h)(2)(D)(i) would further provide 
that Closing IO Orders would not participate in the Closing Auction if 
there is no Unpaired Quantity at the Auction Price. This proposed rule 
text is similarly based on Rule 13(c)(1), but with non-substantive 
differences to use Pillar terminology.
     Proposed Rule 7.35B(h)(3) would address the DMM 
Participant Allocation of at-priced orders in the Closing Auction, 
which would be all of the DMM Participant's orders, regardless of limit 
price. The Exchange proposes that the manner by which DMMs would 
participate in an Auction would differ from how they participate in 
allocations during continuous trading, described above. As proposed:
    [cir] At-priced DMM Orders would be placed on the allocation wheel 
for the Closing Auction based on the time of entry and any other orders 
or interest from such DMM would join that position on the allocation 
wheel (see proposed Rule 7.35B(h)(3)(A)). In such case, the DMM Order 
with the earliest entry time would establish that DMM Participant's 
position on the allocation wheel, consistent with Rule 
7.37(b)(2)(B).\80\ However, if the only DMM Interest available to 
participate in a Closing Auction would be DMM Auction Liquidity or 
better-priced DMM Orders or both, such DMM Interest would be placed 
last on the allocation wheel. Similar to proposed Rule 7.35A(h)(3)(A) 
regarding allocation of DMM Interest in the Core Open or Trading Halt 
Auction, the Exchange proposes that in these scenarios, the DMM 
Interest would go last on the allocation wheel because such orders 
would either be repriced for the Auction (in the case of a better-
priced DMM Order, which would be considered an at-priced order for the 
Auction Allocation) or entered right before the Auction (in the case of 
DMM Auction Liquidity). Because such DMM Interest is intended to be 
offsetting interest for an Auction, the Exchange does not believe that 
such DMM Interest should have time priority in how they are included in 
an allocation wheel over other orders that are eligible to participate 
in an Auction. This proposed functionality would be new on Pillar and 
is designed so that DMMs, who have the ability to enter buy and sell 
interest last in an Auction, would not receive any time priority for 
such interest.
---------------------------------------------------------------------------

    \80\ Rule 7.37(b)(2)(B) provides that additional Participants 
are added to an allocation wheel based on time of entry of the first 
order entered by a Participant.
---------------------------------------------------------------------------

    [cir] A parity allocation to the DMM Participant would be allocated 
in price-time priority (see proposed Rule 7.35B(h)(3)(B)). As discussed 
above, a parity allocation to the DMM Participant would be based on the 
working time. However, in an Auction Allocation, DMM Interest may have 
more than one limit price, and the Exchange proposes that the parity 
allocation to the DMM Participant would be allocated among such DMM 
Interest in price-time priority, even though they all would participate 
in the Auction at a single price.
    SIP Modifier. Proposed Rule 7.35B(i) would provide that the Closing 
Auction would be designated with a modifier to identify it as a Closing 
Auction Trade and that the Exchange would report an Official Closing 
Price, as defined in Rule 1.1, for all Auction-Eligible Securities that 
trade on the Exchange, provided that an Official Closing Price would 
not be reported for a security if there was no Exchange Last Sale Price 
in such security on a trading day. These SIP modifiers are consistent 
with how the Exchange functions under the Current Auction Rules and 
would be new rule text for the Pillar Auction Rules that is based on 
NYSE Arca Rule 7.35E(d)(4) and NYSE American Rule 7.35E(d)(4).
    Temporary Rule Suspensions. Current Rule 123C(9) provides that in 
order to address extreme order imbalances at or near the close, the 
Exchange can temporarily suspend either the hours of the Exchange or 
the prohibition on cancelling or reducing in size MOC, LOC, or CO 
Orders after 3:58 p.m. In the Pillar Auction Rules, the Exchange 
proposes to move these two temporary rule suspension requirements to 
proposed Rule 7.35B(j). The Exchange also proposes a new temporary rule 
suspension for the close that is based on the current Rule 123D(c) 
temporary rule suspension for the open or reopen.
    Proposed Rule 7.35B(j)(1) would set forth the temporary suspension 
of DMM automated closing limitations, which would be new under the 
Pillar Auction Rules. As described above, pursuant to proposed Rule 
7.35B(c)(1)(G), the Exchange proposes to specify designated percentages 
for when a DMM may not close a security electronically. Because this 
proposed rule text is based in part on Rule 123D(a), the Exchange 
similarly proposes a temporary suspension of these automated 
limitations for the close similar to the temporary suspension of 
automated limitations for the open or reopen as set forth in Rule 
123D(c).
    Proposed Rule 7.35B(j)(1)(A) would provide that if the CEO of the 
Exchange, or his or her designee, determines that a Floor-wide event is 
likely to have an impact on the ability of DMMs to arrange for a fair 
and orderly Closing Auction and that, absent relief, the operation of 
the Exchange is likely to be impaired, the CEO of the Exchange may 
temporarily suspend the prohibition on a DMM closing a security 
electronically if the Closing Auction Price would be more than the 
price or volume parameters specified in proposed Rule 7.35B(c)(1)(F) 
and (G). This proposed rule text is based on Rule 123D(c)(1)(A) with 
modifications to apply it to the Closing Auction.
    Proposed Rule 7.35B(j)(1)(B) would provide that in determining 
whether to temporarily suspend proposed Rule 7.35B(c)(1)(F) or (G), the 
CEO of the Exchange would:
     Consider the facts and circumstances that are likely to 
have Floor-wide impact for a particular trading session, including 
volatility in the day's trading session, trading in foreign markets, 
substantial activity in

[[Page 6895]]

the futures market, evidence of pre-closing significant order 
imbalances across the market, government announcements, news and 
corporate events, and such other market conditions that could impact 
Floor-wide trading conditions (see proposed Rule 7.35B(j)(1)(B)(i)). 
This proposed rule text is based on Rule 123D(c)(2)(A) with 
modifications to apply it to the Closing Auction.
     Notify the Chief Regulatory Officer of the Exchange (see 
proposed Rule 7.35B(j)(1)(B)(ii)). This proposed rule text is based on 
Rule 123D(c)(2)(B) with modifications to apply it to the Closing 
Auction.
     Inform the Securities and Exchange Commission staff as 
promptly as practicable of the temporary suspension (see proposed Rule 
7.35B(j)(1)(B)(iii)). This proposed rule text is based on Rule 
123D(c)(2)(C) with modifications to apply it to the Closing Auction.
    Proposed Rule 7.35B(j)(1)(C) would provide that a temporary 
suspension under this Rule will be in effect for the trading day on 
which it was declared only. This proposed rule text is based on Rule 
123D(c)(3) with modifications to apply it to the Closing Auction.
    Proposed Rule 7.35B(j)(2) would set forth in the Pillar Auction 
Rules the temporary suspensions currently available under Rule 
123C(9)(a), with non-substantive differences to use Pillar terminology. 
As proposed, to avoid closing price dislocation that may result from an 
order entered into Exchange systems or represented to a DMM orally at 
or near the end of Core Trading Hours, the Exchange may temporarily 
suspend one of two rules.
    First, pursuant to proposed Rule 7.35B(j)(2)(A), the Exchange may 
temporarily suspend the requirement to enter all order instructions by 
the end of Core Trading Hours (Rule 7.34(a)(2)(B)) \81\ to permit the 
solicitation and entry of orders into Exchange systems. This proposed 
rule text is based on Rule 123C(9)(a)(1) as follows:
---------------------------------------------------------------------------

    \81\ See discussion infra regarding proposed Rule 7.34(a)(2)(B), 
which is based on Rule 52. Currently, Rule 123C(9)(a)(1) permits a 
temporary suspension of the hours of operation, as described in Rule 
52. The Exchange believes that proposed Rule 7.35B(j)(2)(A) achieves 
the same result using Pillar terminology to describe the temporary 
rule suspension.
---------------------------------------------------------------------------

     Such orders would be solicited solely to offset any 
Imbalance in a security that may exist as of the scheduled end of Core 
Trading Hours (see proposed Rule 7.35B(j)(2)(A)(i)). This proposed rule 
text is based on Rule 123C(9)(a)(1)(i) with non-substantive differences 
to use Pillar terminology. Specifically, Rule 123C(9)(a)(1)(i) refers 
to offsetting ``any imbalance'' in a security. Because, as described 
above, the term ``Imbalance'' for the Closing Auction refers to the 
imbalance of Auction-Only Orders, to ensure that the Imbalance used for 
entry of orders during this proposed temporary suspension would reflect 
all orders eligible to trade in the Closing Auction, the Exchange 
proposes to specify that for purposes of proposed Rule 7.35B(j)(2)(A), 
the Imbalance would include all interest eligible to participate in the 
Closing Auction. This proposed rule text makes clear that if this 
temporary rule suspension were triggered, the Imbalance included in the 
Auction Imbalance Information, which would continue to be calculated 
until the Closing Auction begins, would begin to include all orders 
eligible to trade in the Closing Auction.
     The Exchange would disseminate a notice via its 
proprietary data feed and such other methods of communication, as 
determined by the Exchange, that notifies both on-Floor and off-Floor 
participants that the Exchange would be accepting offsetting orders 
after the end of Core Trading Hours up to an order acceptance cut-off 
time designated by the Exchange (the ``Solicitation Period'') (see 
proposed Rule 7.35B(j)(2)(A)(ii)). This proposed rule text is based on 
Rule 123C(9)(a)(1)(ii) with a substantive difference to specify that 
the solicitation would be disseminated both on the Exchange's 
proprietary data feed, which would be new under Pillar Auction Rules, 
and such other methods of communication. For example, the Exchange 
currently notifies member organizations of such solicitations via 
Trader Update. The Exchange proposes to continue using Trader Updates 
and believes that also including this information in its proprietary 
data feed will enable automated systems of Exchange member 
organizations to be able to respond on a more timely basis to such 
solicitation requests. The Exchange also proposes non-substantive 
differences to use Pillar terminology, including a new defined term of 
``Solicitation Period.''
    The proposed rule would further provide that such notification 
would include, at a minimum: (A) The security symbol; (B) the Total 
Imbalance; (C) the Side of the Total Imbalance; and (D) the Exchange 
Last Sale Price. This proposed rule text is also based on Rule 
123C(9)(a)(1)(ii) and uses Pillar terminology to describe the 
information that would be included in the solicitation request.
     If the Side of the Imbalance is buy (sell), during the 
Solicitation Period, the Exchange will accept only sell (buy) Limit 
Orders and Floor Broker Interest with a limit price equal to or higher 
(lower) than the Exchange Last Sale Price. Such orders would not be 
subject to the Limit Order Price Check and would not be routed to an 
Away Market (see proposed Rule 7.35B(j)(2)(A)(iii)). This proposed rule 
text is based on Rule 123C(9)(a)(1)(iii) with non-substantive 
differences to use Pillar terminology. The Exchange proposes new 
functionality under the Pillar Auction Rules. First, because Limit 
Orders are subject to Limit Order Price Protection, the Exchange 
proposes to specify that Limit Orders entered in response to a 
Solicitation Request would not be subject to such price check. Because 
such orders are by their terms, restricted in the limit price 
applicable to such orders, the Exchange does not believe that Limit 
Order Price Protection would be necessary for such orders.
    Second, the Exchange proposes to systemically enforce these order 
entry requirements. Currently, while Rule 123C(9)(a)(1)(iii) requires 
only specified interest to be entered, Exchange systems do not enforce 
this requirement. Under the Pillar Auction Rules, the Exchange proposes 
to enforce these requirements by rejecting orders outside of these 
specified parameters. To specify this new functionality, proposed Rule 
7.35B(j)(2)(A)(iii) would further provide that the Exchange would 
reject all other orders and requests to cancel any orders, regardless 
of the time of entry of the original order. For example, if an order 
was represented before the end of Core Trading Hours, the Exchange 
would not accept a cancellation of such previously-entered order during 
the Solicitation Period. Finally, because Auction Imbalance Information 
would continue to be published up to the beginning of the Auction 
Processing Period for the Closing Auction, the Exchange further 
proposes to provide that orders entered during the Solicitation Period 
would be included in the calculation of the Continuous Book Clearing 
Price.
     The DMM would close the security the earlier of the order 
acceptance cut-off time or if the Imbalance is paired off at or 
reasonably contiguous to the Exchange Last Sale Price (see proposed 
Rule 7.35B(j)(2)(A)(iv)). This proposed rule would further provide that 
for purposes of proposed Rule 7.35B(j)(2)(A), a price reasonably 
contiguous to the Exchange Last Sale Price is within cents of the 
Exchange Last Sale Price and would be a price point that during a 
regular closing auction would not be considered a dislocating closing 
price as compared to

[[Page 6896]]

the Exchange Last Sale Price and that all offsetting interest solicited 
pursuant to proposed Rule 7.35B(j)(2)(A) would be executed consistent 
with proposed Rule 7.35B(h). This proposed rule text is based on Rule 
123C(9)(a)(1)(iv) with non-substantive differences to use Pillar 
terminology and update the rule cross references.
     Finally, if the Exchange solicits orders after the close 
of Core Trading Hours pursuant to proposed Rule 7.35B(j)(2)(A), the 
Total Imbalance information that would be disseminated pursuant to 
proposed Rule 7.35B(e) would begin including all orders eligible to 
participate in the Closing Auction. This proposed rule text would be 
new for the Pillar Auction Rules and reflects that not only would the 
Imbalance be calculated based on all orders eligible to trade in the 
Closing Auction, but the Total Imbalance published during this period 
would also be based on all orders eligible to participate in the 
Closing Auction.
    Second, pursuant to proposed Rule 7.35B(j)(2)(B), the Exchange may 
temporarily suspend the prohibition on canceling an MOC or LOC Order 
after two minutes before the scheduled end of Core Trading Hours 
(proposed Rule 7.35B(f)(2)(B)). This proposed rule text is based on 
Rule 123C(9)(a)(2) with one substantive difference that in Pillar, the 
Exchange would not support being able to reduce the size of a MOC or 
LOC Order if this temporary suspension were invoked. Instead, as 
proposed, if this temporary suspension were invoked, the Exchange would 
be able to fully cancel a MOC or LOC Order only. Based on the Current 
Auction Rules, the Exchange proposes certain qualifications for such 
temporary suspension, provided that:
     The cancellation is necessary to correct a Legitimate 
Error (see proposed Rule 7.35B(j)(2)(B)(i)). This proposed rule text is 
based on Rule 123C(9)(2)(A) with non-substantive differences to use 
Pillar terminology.
     Execution of such an MOC or LOC Order would cause 
significant price dislocation at the close (see proposed Rule 
7.35B(j)(2)(B)(ii)). This proposed rule text is based on Rule 
123C(9)(2)(B) with non-substantive differences to use Pillar 
terminology.
    Proposed Rule 7.35B(j)(3) would provide that only the DMM assigned 
to a particular security may request a temporary suspension under 
proposed Rule 7.35B(j)(2) and that a determination to declare such a 
temporary suspension may be made after the scheduled end of Core 
Trading Hours and would be made on a security-by-security basis. This 
proposed rule text is based on Rule 123C(9)(b) with non-substantive 
differences to use Pillar terminology. Proposed Rule 7.35B(j)(3) would 
further provide that such determination, as well as any entry or 
cancellation of orders or closing of a security under proposed Rule 
7.35B(j)(2) must be supervised and approved by an Executive Floor 
Governor and supervised by an Exchange Officer and that factors that 
may be considered when making such a determination include, but would 
not be limited to, when the order(s) that impacted the Imbalance were 
entered into Exchange systems or orally represented to the DMM, the 
impact of such order(s) on the closing price of the security, the 
volatility of the security during the trading session, and the ability 
of the DMM to commit capital to dampen the price dislocation. This 
proposed rule text is also based on Rule 123C(9)(b) with non-
substantive differences to use Pillar terminology.\82\
---------------------------------------------------------------------------

    \82\ The Exchange also proposes a non-substantive difference to 
reference only the term ``Exchange Floor Governor,'' and not 
reference qualified ICE employees, as such text is redundant. See 
discussion supra note 75. In addition, because the Exchange no 
longer has Rule 48, the Exchange proposes to simply reference an 
Exchange Officer, which is a term used in other Exchange rules, such 
as Rule 7.10.
---------------------------------------------------------------------------

    Finally, proposed Rule 7.35B(j)(4) would provide that a temporary 
suspension under proposed Rule 7.35B(j)(2) would be in effect only for 
the particular security for which such suspension has been granted and 
for that trading day. This proposed rule text is based on Rule 
123C(9)(c) with non-substantive differences to update the rule cross 
references.
Proposed Rule 7.35C (Exchange-Facilitated Auctions)
    As discussed above, DMMs have an obligation to facilitate Auctions 
and therefore both the Current Auction Rules and proposed Pillar 
Auction Rules, described above, contemplate that the DMM will 
facilitate Auctions. The Current Auction Rules also provide for how the 
Exchange would facilitate an Auction if a DMM cannot facilitate the 
opening or closing of trading. In such circumstances, Rule 123D(a)(2)-
(6) sets forth how the Exchange would facilitate the opening or 
reopening of securities and Supplementary Material .10 to Rule 123C 
sets forth how the Exchange would facilitate the closing of 
securities.\83\
---------------------------------------------------------------------------

    \83\ See Securities Exchange Act Release No. 76290 (October 28, 
2015), 80 FR 67822 (November 3, 2015) (SR-NYSE-2015-49) (Notice of 
filing and immediate effectiveness of proposed rule change to Rule 
123D) and Securities Exchange Act Release No. 74006 (January 6, 
2015), 80 FR 1567 (January, 12, 2015) (SR-NYSE-2014-73) (Notice of 
filing and immediate effectiveness of proposed rule change to Rule 
123C). The Exchange has never facilitated either an opening or 
closing of any security on the Exchange.
---------------------------------------------------------------------------

    When Exchange-listed securities transition to Pillar, the Exchange 
proposes that new Rule 7.35C (Exchange-Facilitated Auctions) would 
describe how the Exchange would facilitate an Auction in one or more 
securities if the DMM cannot. Similar to how the Current Auction Rules 
function, because the Exchange would not supply any liquidity when 
facilitating an Auction, under proposed Rule 7.35C, the Exchange would 
not open, reopen, or close a security at a price outside of defined 
numerical parameters. In addition, similar to the Current Auction 
Rules, orders that would have otherwise participated in an Auction 
under Rule 7.35A, but which may not participate in an Exchange-
facilitated Auction because of such numerical parameters, will be 
cancelled.
    While the basic premise of how Exchange-facilitated Auctions on 
Pillar would not change, with the availability of Pillar technology, 
the Exchange proposes enhancements to this process that are based on 
how NYSE Arca and NYSE American operate electronic auctions, including 
using an Indicative Match Price to determine how to price the Auction, 
use of Auction Collars, and extension logic for reopenings following a 
trading pause.
    Proposed Rule 7.35C(a) would provide that if a DMM cannot 
facilitate an Auction for one or more securities in which the DMM is 
registered under proposed Rules 7.35A or 7.35B, the Exchange would 
conduct the Auction for such security or securities electronically as 
provided for in proposed Rule 7.35C. This proposed rule text is based 
in part on the first sentence of Rule 123D(a)(2) and the first sentence 
of the second paragraph of Supplementary Material .10 to Rule 123C. The 
Exchange proposes non-substantive differences to use Pillar technology 
and cross reference Pillar Auction Rules.
    Proposed Rule 7.35C(a)(1) would provide that before the Exchange 
facilitates an Auction, previously-entered DMM Interest would be 
cancelled, the Exchange would not accept new DMM Interest, and Floor 
Broker Interest that has not been electronically accepted by the DMM 
would not participate in an Exchange-facilitated Closing Auction. This 
proposed rule text is based in part on the second sentence of Rule 
123D(a)(2) and the second sentence of the second paragraph of 
Supplementary Material .10 to Rule 123, which each provide that

[[Page 6897]]

``[m]anually-entered Floor interest will not participate in any 
[opening/closing] effectuated electronically by the Exchange and if 
previously entered, will be ignored.'' The Exchange proposes non-
substantive differences to use Pillar terminology. The Exchange also 
proposes a substantive difference that all DMM Interest would be 
cancelled--not just DMM Interest entered on the Trading Floor by a DMM. 
In addition, to reflect the new Floor Broker Interest functionality, 
described above in proposed Rule 7.35B(a)(1), the Exchange proposes 
that if a DMM has already accepted such interest, and then the Exchange 
facilitates a Closing Auction, such interest would be eligible to 
participate in that Closing Auction. However, if the DMM has not 
accepted such interest, and therefore that interest has not yet been 
validated, it would not be eligible to participate in an Exchange-
facilitated Closing Auction.
    Proposed Rule 7.35C(a)(2) would provide that a security subject to 
an Exchange-facilitated Core Open Auction, IPO Auction, Direct Listing 
Auction, or Trading Halt Auction may open or reopen with a trade or a 
quote. This proposed rule text is based in part on Rule 123D(a)(3) and 
(a)(4), which describe how an opening or reopening can be on a trade or 
a quote.
    Proposed Rule 7.35C(b) would set forth definitions that would be 
used for purposes of proposed Rule 7.35C only. Proposed Rule 
7.35C(b)(1) would define the term ``Auction Reference Price,'' which is 
a term defined in NYSE Arca Rule 7.35-E(a)(8)(A) and NYSE American Rule 
7.35E(a)(8)(A). As described below, the Auction Reference Price would 
be used by the Exchange, and is used by NYSE Arca and NYSE American, 
for purposes of calculating the Indicative Match Price and Auction 
Collars.
    The Exchange proposes a difference from NYSE Arca and NYSE American 
because the Auction Reference Price that would be used for a particular 
Auction would be based on the Imbalance Reference Price, described 
above, for such Auctions. As proposed, the Auction Reference Price for 
the Core Open Auction would be the Imbalance Reference Price as 
determined under proposed Rule 7.35A(e)(3), described above. And, 
except as provided for in proposed Rule 7.35C(e), described below, the 
Auction Reference Price for a Trading Halt Auction would also be the 
Imbalance Reference Price as determined under proposed Rule 
7.35A(e)(3), described above. The proposed Auction Reference Price for 
the Closing Auction would be the Imbalance Reference Price as 
determined under proposed Rule 7.35B(e)(3).
    Finally, because the Exchange proposes to have functionality 
available to facilitate an IPO or Direct Listing Auction, the Exchange 
proposes that the Auction Reference Price for such Auctions would be a 
price determined under proposed Rule 1.1(s)(1)(F). Pursuant to that 
rule, the Exchange determines the Official Closing Price for a security 
that is a new listing and does not have any consolidated last-sale 
eligible trades on its first trading day based on a derived last sale 
associated with the price of such security before it begins trading on 
the Exchange. As noted above, pursuant to Rule 123C(1)(e)(i)(C), the 
Exchange already determines the Official Closing Price in this manner 
for new listings. As proposed, this price would be used as the Auction 
Reference Price if the Exchange were to facilitate an IPO or Direct 
Listing Auction.
    Proposed Rule 7.35C(b)(2) would define the term ``Indicative Match 
Price'' to mean the best price at which the maximum volume of shares, 
including the non-displayed quantity of Reserve Orders, would be 
tradable in the applicable Auction, subject to the Auction Collars. 
This proposed definition is based on NYSE Arca Rule 7.35-E(a)(8) and 
NYSE American Rule 7.35E(a)(8) without any differences. With the 
exception of which Auction Reference Price would be used by the 
Exchange when it facilitates an Auction, the manner by which the 
Exchange would determine the Indicative Match Price would be based on 
NYSE Arca and NYSE American rules without any differences, as follows:
     Proposed Rule 7.35C(b)(2)(A) would provide that if there 
are two or more prices at which the maximum volume of shares would be 
tradable, the Indicative Match Price would be the price closest to the 
Auction Reference Price, provided that the Indicative Match Price would 
not be lower (higher) than the price of an order to buy (sell) ranked 
Priority 2--Display Orders that was eligible to participate in the 
applicable Auction. This proposed rule is based on NYSE Arca Rule 7.35-
E(a)(8)(A) and NYSE American Rule 7.35E(a)(8)(A) without any 
differences.
     Proposed Rule 7.35C(b)(2)(B) would provide that if there 
are two prices at which the maximum volume of shares would be tradable 
and both prices are equidistant to the Auction Reference Price, the 
Indicative Match Price would be the Auction Reference Price. This 
proposed rule is based on NYSE Arca Rule 7.35-E(a)(8)(B) and NYSE 
American Rule 7.35E(a)(8)(B) without any differences.
     Proposed Rule 7.35C(b)(2)(C) would provide that if the 
Paired Quantity for an auction consists of buy and sell Market Orders 
only, the Indicative Match Price would be the Auction Reference Price. 
This proposed rule is based on NYSE Arca Rule 7.35-E(a)(8)(C) and NYSE 
American Rule 7.35E(a)(8)(C) with a difference that the Auction 
Reference Price would be used for all Auctions, whereas the NYSE Arca 
and NYSE American rules use a different reference price for the Closing 
Auction.
     Proposed Rule 7.35C(b)(2)(D) would provide that if there 
is a BBO, but no Paired Quantity, the Indicative Match Price for the 
Auction Imbalance Information would be (i) the side of the BBO that has 
the higher volume, or (ii) if the volume of the BB equals the volume of 
the BO, the BB. This proposed rule text is based on NYSE Arca Rule 
7.35-E(a)(8)(D) and NYSE American Rule 7.35E(a)(8)(D) with a non-
substantive difference to use the term ``Paired Quantity,'' which is 
defined in proposed Rule 7.35(a) above, instead of the term ``Matched 
Volume,'' which is a defined term on NYSE Arca and NYSE American that 
has the same meaning as the term ``Paired Quantity.''
     Proposed Rule 7.35C(b)(2)(E) would provide that if there 
is no Paired Quantity and Market Orders on only one side of the market, 
the Indicative Match Price for the Auction Imbalance Information would 
be zero. This proposed rule text is based on NYSE Arca Rule 7.35-
E(a)(8)(E) and NYSE American Rule 7.35E(a)(8)(E) with a non-substantive 
difference to use the term ``Paired Quantity'' instead of the term 
``Matched Volume.''
     Proposed Rule 7.35C(b)(2)(F) would provide that if the 
Indicative Match Price is not in the MPV for the security, it would be 
rounded to the nearest price at the applicable MPV. This proposed rule 
text is based on NYSE American Rule 7.35E(a)(8)(F) with a non-
substantive difference not to include rule text referring to an 
Indicative Match Price based on the midpoint of the ``Auction NBBO,'' 
as this is a feature that the Exchange does not propose to include in 
Rule 7.35C.
    Proposed Rule 7.35C(b)(3) would define the term ``Auction Collar'' 
to mean the price collar thresholds for the Indicative Match Price for 
an Auction. This proposed rule text is based on NYSE Arca Rule 7.35-
E(a)(10) and NYSE American Rule 7.35E(a)(10) without any substantive 
differences. The Exchange further proposes that there would be no 
Auction Collars for

[[Page 6898]]

an IPO Auction or Direct Listing Auction. This proposed rule text is 
based in part on NYSE Arca Rule 7.35-E(f)(2) and NYSE American Rule 
7.35E(f)(2), which provide than an IPO Auction on those exchanges would 
not be subject to Auction Collars. Because the Exchange proposes to 
process Direct Listing Auctions similarly to an IPO Auction, the 
Exchange proposes that if it facilitates a Direct Listing Auction, it 
would similarly not be subject to Auction Collars.
    Proposed Rule 7.35C(b)(3)(A) would provide that the upper (lower) 
boundary of the Auction Collar would the Auction Reference Price 
increased (decreased) by either a specified amount or specified 
percentage, as applicable, rounded to the nearest MPV, provided that 
the lowest Auction Collar would be one MPV above $0.00. This proposed 
method of calculating the Auction Collar is identical to how NYSE Arca 
and NYSE American calculate an Auction Collar.\84\
---------------------------------------------------------------------------

    \84\ See NYSE Arca Rule 7.35-E(a)(10)(A) (third sentence) and 
NYSE American Rule 7.35E(a)(10)(A) (third sentence).
---------------------------------------------------------------------------

     Proposed Rule 7.35C(b)(3)(A)(i) would provide that except 
as provided for in proposed Rule 7.35C(e)(4), described below, the 
Auction Collar for the Core Open Auction and the Closing Auction will 
be based on a price that is the greater of $0.15 or 10% away from the 
Auction Reference Price for the applicable Auction. This proposed 
Auction Collar is based in part on NYSE American Rule 7.35E(a)(10)(A), 
which also uses an Auction Collar for its Core Open Auction and Closing 
Auction that is $0.50 or 10% away from the Auction Reference Price. The 
Exchange proposes a substantive difference to use $0.15 as the 
breakpoint rather than $0.50. The Exchange believes this would simplify 
the operation of this functionality as it would use the same breakpoint 
as the proposed specified price for Auction Collars for Trading Halt 
Auctions.
     Proposed Rule 7.35C(b)(3)(A)(ii) would provide that except 
as provided for in proposed Rule 7.35C(e), described below, the Auction 
Collar for the Trading Halt Auction would be based on a price that is 
the greater of $0.15 or 5% away from the Auction Reference Price for 
the Trading Halt Auction. This proposed rule is based on NYSE Arca Rule 
7.35-E(e)(7) and NYSE American Rule 7.35E(e)(7), which also has a price 
collar threshold of the greater of $0.15 or 5% away from the Auction 
Reference price.\85\
---------------------------------------------------------------------------

    \85\ In the NYSE Arca and NYSE American rules, this specified 
amount is described as ``[f]or securities with an Auction Reference 
Price above $3.00, the Price Collar Threshold for Auction Collars 
will be the Auction Reference Price multiplied by 5 percent. For 
securities with an Auction Reference Price $3.00 and below, the 
Price Collar Threshold for Auction Collars will be $0.15.'' 
Mathematically, using the phrase ``the greater of $0.15 or 5%'' 
leads to the same result. Therefore, even though the Exchange 
proposes to use different text, it is substantively the same as the 
Auction Collar on NYSE Arca and NYSE American.
---------------------------------------------------------------------------

    Proposed Rule 7.35C(b)(3)(B) would provide that an Indicative Match 
Price that is higher (lower) than the upper (lower) boundary of the 
Auction Collar would be adjusted to the upper (lower) boundary of the 
Auction Collar and orders eligible to participate in the applicable 
auction would trade at the collared Indicative Match Price. This 
proposed rule text is based on NYSE Arca Rule 7.35-E(a)(10)(B) and NYSE 
American Rule 7.35E(a)(10)(B) without any differences.
    Proposed Rule 7.35C(c) would describe Auction Imbalance Information 
for Exchange-facilitated Auctions. As proposed, if it is determined 
that the Exchange will facilitate an Auction:
     The Exchange would disseminate Auction Imbalance 
Information as provided for in proposed Rule 7.35A(e) for an Exchange-
facilitated Core Open, IPO, Direct Listing, or Trading Halt Auction 
(see proposed Rule 7.35C(c)(1)). Proposed Rule 7.35C(c)(1)(A) would 
further provide that a pre-opening indication, as described in proposed 
Rule 7.35A(d), would not be required for an Exchange-facilitated 
Auction. This proposed rule text is based in part on Rule 123D(a)(5), 
which provides that when the Exchange facilitates the opening or 
reopening of a security, it will publish Order Imbalance Information 
described in Rule 15(g), but will not issue pre-opening indications 
pursuant to Rule 15(a). Rule 123D(a)(5) further provides that the 
Exchange will publish a pre-opening indication pursuant to Rule 15(a) 
for a re-opening following a regulatory halt. However, as described 
above, on Pillar, the Exchange would never publish a pre-opening 
indication, and therefore, the Exchange proposes a difference on Pillar 
that when facilitating a reopening following a regulatory halt, the 
Exchange would not publish a pre-opening indication.
    This proposed rule text also makes it explicit that if the Exchange 
facilitates an IPO or Direct Listing Auction, the Exchange would 
publish Auction Imbalance Information. As described above, the Exchange 
would not publish Auction Imbalance Information when a DMM facilitates 
such an Auction. The Exchange believes it is appropriate to disseminate 
Auction Imbalance Information if the Exchange facilitates such an 
Auction because there would be no Floor-based trading relating to that 
security.
     The Exchange would disseminate Closing Imbalance and 
Auction Imbalance Information as provided for in proposed Rules 
7.35B(d) and (e) for an Exchange-facilitated Closing Auction (see 
proposed Rule 7.35C(c)(2)). Proposed Rule 7.35C(c)(2)(A) would further 
provide that entry and cancellation of orders for the Closing Auction 
would be subject to the Auction Imbalance Freeze as provided for in 
proposed Rule 7.35B(f), described above. This proposed rule text is 
based on Rule 123C generally because if the Exchange were to facilitate 
a closing transaction pursuant to Supplementary Material .10 to Rule 
123C, there is nothing in that rule that suspends the requirements 
specified in Rule 123C(1)-(6) for such scenario.\86\
---------------------------------------------------------------------------

    \86\ For example, Rule 123C.10(b) specifies that the provisions 
of Rules 123C(9)(a)(1) and 123C(9)(b) would be suspended if the 
Exchange facilitates the closing transaction. The absence of a 
reference that Rules 123C(1)-(6) would not be suspended means that 
those rules would still be applicable.
---------------------------------------------------------------------------

     The Auction Imbalance Information would begin including 
the Indicative Match Price, the Auction Collars, and, for a Trading 
Halt Auction pursuant to proposed Rule 7.35C(e), described below, an 
indicator of whether an Auction could be conducted, based on the 
applicable Auction Collar, and the number of extensions (see proposed 
Rule 7.35C(c)(3)). This proposed rule text would be new and is based on 
the information included in the Auction Imbalance Information 
disseminated by NYSE Arca and NYSE American.\87\ The Exchange believes 
that if it facilitates an Auction, including this information in the 
Auction Imbalance Information would promote transparency regarding the 
price at which such Auction could or could not occur.
---------------------------------------------------------------------------

    \87\ See NYSE Arca Rule 7.35-E(a)(4) and NYSE American Rule 
7.35E(a)(4).
---------------------------------------------------------------------------

    Proposed Rule 7.35C(d) would describe the DMM's role in an 
Exchange-facilitated Auction. A DMM may be unable to facilitate an 
Auction for a myriad of reasons, ranging from the unavailability of the 
Trading Floor to a technology issue with a single DMM's graphical user 
interface on the Trading Floor. Because in these scenarios, it could be 
feasible for the DMM to facilitate an Auction electronically (which 
does not require a Floor presence), the Exchange proposes that before 
the Exchange facilitates an Auction, if feasible, the DMM should first 
be provided an opportunity to facilitate an Auction electronically.\88\
---------------------------------------------------------------------------

    \88\ For example, if a security is not open by 9:30 a.m. and 
then it is determined that the Exchange would need to facilitate the 
Core Open Auction for such security, it would not be feasible to 
request the DMM to electronically facilitate such Auction.

---------------------------------------------------------------------------

[[Page 6899]]

    Proposed Rule 7.35C(d) would provide that before facilitating an 
Auction under this Rule, the Exchange may provide the DMM with the 
opportunity to electronically facilitate an Auction pursuant to Rules 
7.35A or 7.35B. Providing the DMM with an opportunity to facilitate an 
Auction pursuant to Rule 7.35A and 7.35B would allow for the DMM to 
supply liquidity as needed pursuant to Rule 104(a)(2) or (3) so that 
all better-priced orders on the Side of the Imbalance could be 
satisfied at a price at or within the Auction Collars. However, the 
Exchange recognizes that there would need to be differences if a DMM 
were to electronically facilitate an Auction in such circumstances.
     Proposed Rule 7.35C(d)(1) would provide that the 
limitations on a DMM facilitating an Auction electronically specified 
in Rules 7.35A(c)(1)(E) (reopening following a regulatory halt), 
7.35A(c)(1)(G) and (H) (price and paired volume limitations for the 
Core Open and Trading Halt Auctions), and 7.35B(c)(1)(G) and (H) (price 
and paired volume limitations for the Closing Auction) would not be 
applicable. With these proposed exceptions, a DMM would be able to 
facilitate a Trading Halt Auction following a regulatory halt 
electronically, which would otherwise not be permitted (under normal 
operating conditions, the Exchange expects the DMM to facilitate such 
Auction manually). In addition, the Exchange would no longer require 
the paired volume and price limitations for such Auctions.
     Proposed Rule 7.35C(d)(2) would provide that a pre-opening 
indication pursuant to Rule 7.35A(d) would not be required. Because a 
pre-opening indication is published by a DMM on the Trading Floor, a 
DMM that is facilitating an Auction electronically would not be able to 
publish such indication. Accordingly, the Exchange proposes it would 
not be applicable in such circumstances.
     Proposed Rule 7.35C(d)(3) would provide that if the DMM 
does not select an Auction Price consistent with Rule 7.35A(g) or 
7.35B(g) that is at or within the specified Auction Collar, the 
Exchange would facilitate the Auction pursuant to this Rule. As noted 
above, DMMs would not be subject to the price limitations specified in 
Rules 7.35A(c)(1)(G) or 7.35B(c)(1)(G). However, the Exchange also 
believes that in such circumstances, the price of such an Auction 
should be bound by the Auction Collars, described above. Accordingly, 
the DMM would need to select an Auction Price that is at or within the 
Auction Collars. If the DMM does not select such an Auction Price, the 
Exchange would proceed with facilitating the Auction. If the Exchange 
were to facilitate an Auction, as described below, this would allow for 
a process to cancel specified orders that were not included in such an 
Auction.
    Proposed Rule 7.35C(e) would set forth the extension logic for a 
Trading Halt Auction following a trading pause, which the Exchange 
would define as an ``LULD Auction.'' As noted above, the Exchange 
proposes to apply extension logic that is currently available on NYSE 
Arca and NYSE American for all Trading Halt Auctions to LULD Auctions 
only. The Exchange believes that making such extension logic available 
to LULD Auctions only would be consistent with the Regulation NMS Plan 
to Address Extraordinary Market Volatility (``LULD Plan'') while at the 
same time streamlining the operation of Exchange-facilitated Auctions, 
which are not the primary method of conducting Auctions at the 
Exchange.\89\
---------------------------------------------------------------------------

    \89\ See Securities Exchange Act Release No. 83044 (April 12, 
2018), 83 FR 17205 (April 18, 2018) (File No. 4-631) (Order 
approving seventeenth amendment to LULD Plan to extend pilot period 
of LULD Plan to April 15, 2018). The LULD Plan Participants have 
filed to make the LULD Plan permanent. See Securities Exchange Act 
Release No. 84843 (December 18, 2018), 83 FR 66464 (December 26, 
2018) (File No. 4-631) (Notice of filing of eighteenth amendment to 
LULD Plan).
---------------------------------------------------------------------------

    As proposed, the Exchange would attempt to facilitate an LULD 
Auction following a trading pause under Rule 7.11 (``Trading Pause'') 
at the scheduled end of the Trading Pause, which would be defined as 
the initial ``Reopening Time.'' This proposed rule text is based in 
part on NYSE Arca Rule 7.35-E(e)(2) and NYSE American Rule 7.35E(e)(2), 
which describe when the initial Reopening Time would be for a Trading 
Pause under those rules, with a non-substantive difference to use the 
term ``Reopening'' instead of the term ``Re-Opening.''
    Proposed Rule 7.35C(e)(1) would provide that an LULD Auction would 
not be conducted if, at the Reopening Time, the Indicative Match Price, 
before being adjusted based on Auction Collars, is below (above) the 
Lower (Upper) Auction Collar or if there is an Imbalance of sell (buy) 
Market Orders (either, an ``Impermissible Price''). This proposed rule 
text is based in part on NYSE Arca Rule 7.35-E(e)(5) and NYSE American 
Rule 7.35E(e)(5). Unlike NYSE Arca and NYSE American, the Exchange does 
not disseminate a ``Market Imbalance.'' Accordingly, the Exchange 
proposes a difference to its proposed rule text to refer to an 
``Imbalance of sell (buy) Market Orders.'' Otherwise, the basis for why 
the Exchange would not conduct an LULD Auction at the initial Reopening 
Time is no different than as on NYSE Arca or NYSE American.
    Proposed Rule 7.35C(e)(2) would provide that the Reopening Time for 
an LULD Auction would be extended as follows:
     If there is an Impermissible Price at the initial 
Reopening Time, the Trading Pause would be extended an additional five 
minutes and a new Reopening Time would be disseminated (``First 
Extension'') and the Exchange would not conduct an LULD Auction before 
the Reopening Time for the First Extension (see proposed Rule 
7.35C(e)(2)(A)). This proposed rule text is based on NYSE Arca Rule 
7.35-E(e)(6)(A) and NYSE American Rule 7.35E(e)(6)(A) without any 
substantive differences.
     If there is an Impermissible Price at the end of the First 
Extension, the Trading Pause would be extended an additional five 
minutes and a new Reopening Time would be disseminated (``Subsequent 
Extension'') and the Exchange would conduct an LULD Auction before the 
Reopening Time for a Subsequent Extension if the Indicative Match 
Price, before being adjusted based on Auction Collars, is at or within 
the applicable Auction Collars and there is no Imbalance of Market 
Orders (see proposed Rule 7.35C(e)(2)(B)). This proposed rule text is 
based on NYSE Arca Rule 7.35-E(e)(6)(B) and NYSE American Rule 
7.35E(e)(6)(B) without any substantive differences.
     The Trading Pause would continue to be extended if there 
is an Impermissible Price at the Reopening Time for a Subsequent 
Extension (see proposed Rule 7.35C(e)(2)(C)). This proposed rule text 
is based on NYSE Arca Rule 7.35-E(e)(6)(C) and NYSE American Rule 
7.35E(e)(6)(C) without any substantive differences.
    Proposed Rule 7.35C(e)(3) would set forth the Auction Collars for 
such LULD Auctions. As proposed, for securities with an Auction 
Reference Price above $3.00, the Price Collar Threshold for Auction 
Collars would be the Auction Reference Price multiplied by 5 percent 
and for securities with an Auction Reference Price $3.00 and below, the 
Price Collar Threshold for Auction Collars would be $0.15. This 
proposed rule text is based on NYSE Arca Rule 7.35-E(e)(7) and NYSE 
American Rule 7.35E(e)(7) without any substantive differences.

[[Page 6900]]

     Proposed Rule 7.35C(e)(3)(A) would specify the Auction 
Reference Price for LULD Auctions as follows: If the Limit State that 
preceded the Trading Pause was at the Lower (Upper) Price Band, the 
Auction Reference Price would be the Lower (Upper) Price Band. This 
proposed rule text is based on NYSE Arca Rule 7.35-E(e)(7)(A) and NYSE 
American Rule 7.35E(e)(7)(A) without any substantive differences.
     Proposed Rule 7.35C(e)(3)(B) would specify the Initial 
Auction Collars for an LULD Auction as follows: At the initial 
Reopening Time, if the Auction Reference Price is the Lower (Upper) 
Price Band, the Lower (Upper) Auction Collar would be the Auction 
Reference Price decreased (increased) by the Price Collar Threshold, 
rounded to the nearest MPV, provided that the lowest Auction Collar 
would be one MPV above $0.00, and the Upper (Lower) Auction Collar 
would be the Upper (Lower) Price Band. This proposed rule text is based 
on NYSE Arca Rule 7.35-E(e)(7)(B)(i) and NYSE American Rule 
7.35E(e)(7)(B)(i) without any substantive differences.
     Proposed Rule 7.35C(e)(3)(C) would specify the Auction 
Collars for Extensions for an LULD Auction as follows: The Auction 
Collar on the side of the Impermissible Price would be widened for each 
Extension and the Auction Collar on the opposite side of the 
Impermissible Price would remain the same as the last-calculated 
Auction Collar on that side. The proposed rule would further provide 
that (i) if the Impermissible Price is on the side of the Lower (Upper) 
Auction Collar, the last-calculated Lower (Upper) Auction Collar would 
be decreased (increased) by a Price Collar Threshold and the Upper 
(Lower) Auction Collar would stay the same; and (ii) if the side of the 
Impermissible Price changes from the Lower (Upper) Auction Collar to 
the Upper (Lower) Auction Collar, the last-calculated Upper (Lower) 
Auction Collar would be widened for that Extension and the last-
calculated Lower (Upper) Auction Collar would remain the same. This 
proposed rule text is based on NYSE Arca Rule 7.35-E(e)(7)(C) and 
subparagraph (i) and (ii) thereto and NYSE American Rule 7.35E(e)(7)(C) 
and subparagraph (i) and (ii) thereto without any substantive 
differences.
    Proposed Rule 7.35C(e)(4) would provide that as provided for in 
proposed Rule 7.35(d), described above, if the Reopening Time for an 
LULD Auction under this Rule would be in the last ten minutes of 
trading before the end of Core Trading Hours, the Exchange would not 
conduct an LULD Auction and will not transition to continuous trading 
and in such case, the Auction Collars for the Exchange-facilitated 
Closing Auction would be the most recently widened Auction Collars for 
the LULD Auction that did not occur. This proposed rule text is based 
in part on NYSE Arca Rule 7.35-E(e)(10)(B) and NYSE American Rule 
7.35E(e)(10)(B) with non-substantive differences because, as described 
above, the Exchange proposes to specify in proposed Rule 7.35(d) that 
the Exchange would not reopen trading in the last ten minutes of 
trading before the end of Core Trading Hours. Accordingly, proposed 
Rule 7.35C(e)(4) is more narrowly tailored to specify what the Auction 
Collars for the Closing Auction would be if the Reopening Time for an 
LULD Auction were to be in the last ten minutes of trading. In such 
case, the Exchange proposes the same methodology as NYSE Arca and NYSE 
American.
    Proposed Rule 7.35C(f) would set forth the auction allocation 
methodology for Exchange-facilitated Auctions. As proposed, all orders 
eligible to trade in the applicable Auction would be matched and traded 
at the Indicative Match Price. As described above, this Indicative 
Match Price would already be subject to the applicable Auction Collars. 
Accordingly, with this proposed rule text, the Exchange would never 
facilitate an Auction at a price outside the Auction Collars.
    Proposed Rule 7.35C(f) would further provide that orders eligible 
to trade in an Auction would be ranked as provided for in Rule 7.36(c)-
(g) consistent with the priority ranking associated with each order. 
This proposed rule text is based on the second sentence of NYSE Arca 
Rule 7.35-E(a)(6) and the second sentence of NYSE American Rule 
7.35E(a)(6).
    The Exchange proposes to specify this ranking because, unlike 
proposed Rules 7.35A(g) and 7.35B(g), in an Exchange-facilitated 
Auction, not all better-priced orders would be guaranteed to 
participate. In such case, the Exchange proposes that orders would be 
allocated in the following order:
     Better-priced orders would be traded in price-time 
priority (see proposed Rule 7.35C(f)(1)).
     At-priced orders would be traded as described in Rule 
7.35A(h) (for Core Open and Trading Halt Auctions) or Rule 7.35B(h) 
(for Closing Auctions).
    This proposed allocation methodology is based in part on current 
Rule 123D(a)(3)(C), but with differences to use both the existing NYSE 
Arca and NYSE American allocation methodology for better-priced orders, 
which would be based on how the orders are ranked pursuant to Rule 
7.36(c)-(g), and the Exchange's proposed auction allocation model under 
Pillar for at-priced orders, which would include parity allocations, as 
applicable, as described in proposed Rule 7.35A(h)(2) and 7.35B(h)(2). 
The Exchange proposes to use price-time priority for better-priced 
orders because when the Exchange facilitates an Auction, such orders 
would no longer be guaranteed to participate.
    Finally, proposed Rule 7.35C(g) would specify the treatment of 
unexecuted orders. Proposed Rule 7.35C(g)(1) would provide that if a 
security opens or reopens on a trade, orders that are better-priced 
than the Auction Price and were not executed in the applicable Auction 
would be cancelled. This proposed rule is based in part on Rule 
123D(a)(6), which similarly provides that better-priced orders would be 
cancelled after an Exchange-facilitated Auction.
    Proposed Rule 7.35C(g)(2) would provide that if a security opens or 
reopens on a quote that is above (below) the upper (lower) Auction 
Collar, buy (sell) orders better-priced than the upper (lower) Auction 
Collar would be cancelled before such quote is published. This proposed 
rule text is based in part on Rule 123D(a)(6)(C) with non-substantive 
differences to use Pillar terminology and a substantive difference that 
the Exchange would cancel such orders before publishing a quote.
Proposed Amendments to Rule 7.11 (LULD Plan)
    Rule 80C addresses the LULD Plan and related Trading Pauses for 
Exchange-listed securities.\90\ Rule 7.11 addresses the LULD Plan for 
UTP Securities. To set forth the Exchange's role in re-opening 
Exchange-listed securities following a Trading Pause on Pillar, the 
Exchange proposes to amend Rule 7.11(b) to add rule text based on both 
Rule 80C(b) and NYSE Arca Rule 7.11-E(b) and NYSE American Rule 
7.11E(b).
---------------------------------------------------------------------------

    \90\ The term ``Trading Pause'' as used in Rule 80C and proposed 
Rule 7.11 has the same meaning as the defined term in the LULD Plan.
---------------------------------------------------------------------------

    First, the Exchange proposes to delete the existing text under Rule 
7.11(b)(1), which no longer represents how exchanges trading securities 
on an unlisted trading privileges basis may reopen securities subject 
to a Trading Pause.\91\
---------------------------------------------------------------------------

    \91\ This proposed rule change aligns Rule 7.11(b) with the same 
rules of NYSE Arca and NYSE American, which were previously amended. 
See Securities Exchange Act Release Nos. 79846 (January 19, 2017), 
82 FR 8548 (January 26, 2017) (SR-NYSEArca-2016-130) (Approval 
Order) and 81968 (October 27, 2017), 82 FR 50898 (November 2, 2017) 
(SR-NYSEAmerican-2017-30) (Notice of filing and immediate 
effectiveness of proposed rule change).

---------------------------------------------------------------------------

[[Page 6901]]

    Second, the Exchange proposes to add to paragraph (b) of Rule 7.11 
to provide that at the end of the Trading Pause, the Exchange would re-
open the security in accordance with the procedures set forth in the 
Rule 7.35 Series for a Trading Halt Auction and that any interest 
repriced pursuant to paragraph (a)(5) of this Rule would return to its 
original order instructions for purposes of the re-opening transaction 
following a Trading Pause. This proposed rule text is based on Rule 
80C(b) with a non-substantive difference to update the rule cross 
reference.\92\
---------------------------------------------------------------------------

    \92\ See also NYSE Arca Rule 7.11-E(b) and NYSE American Rule 
7.11E(b).
---------------------------------------------------------------------------

    Third, the Exchange proposes to add subparagraph (b)(1) of Rule 
7.11 to provide: Notification of Trading Pauses. If a Trading Pause is 
triggered under this Rule or if the Exchange is unable to reopen 
trading at the end of the Trading Pause due to a systems or technology 
issue, the Exchange will immediately notify the single plan processor 
responsible for consolidation of information for the security pursuant 
to Rule 603 of Regulation NMS under the Securities Exchange Act of 
1934.
    This proposed rule text is based on Rule 80C(b)(1) without any 
differences.
    Finally, the Exchange proposes to add subparagraph (b)(2) of Rule 
7.11 to provide that if a primary listing market issues a Trading 
Pause, the Exchange would resume trading as provided for in Rule 
7.18(b). Because Rule 80C is not applicable to UTP Securities that 
trade on the Pillar trading platform, Rule 80C does not currently 
include this rule text. Instead, this proposed rule text is based on 
NYSE Arca Rule 7.11-E(b)(2) and NYSE American Rule 7.11E(b)(2) with a 
non-substantive difference to update the rule cross reference to an 
Exchange rule.
    In connection with this change, the Exchange proposes to amend the 
preamble to Rule 80C so that it provides that ``[t]his Rule is not 
applicable to trading on the Pillar trading platform.''
Proposed Amendments to Rule 7.12 (Market-Wide Circuit Breakers)
    Rule 80B addresses trading halts due to extraordinary market 
volatility and is a common rule across all equities exchanges. For 
trading on Pillar, the Exchange proposes that the text governing 
trading halts due to extraordinary market volatility will be included 
under Rule 7.12, which is aligned with the same rule number for NYSE 
Arca and NYSE American. The Exchange does not propose any substantive 
differences to Rule 7.12 as compared to Rule 80B. The Exchange proposes 
that the preamble paragraph, which addresses the pilot period for the 
rule, would continue to reference Rule 80B, because if the pilot is not 
approved as permanent, then the prior version of Rule 80B would be in 
effect for the Exchange (there is no prior version of Rule 7.12 for the 
Exchange). The Exchange proposes a second non-substantive difference to 
replace the cross reference in Rule 7.12(c)(1) from Rule 123D to 
instead reference the Rule 7.35 Series, which as discussed above, would 
address Trading Halt Auctions.
    The Exchange also proposes to amend Rule 7.18(a) to update a rule 
cross reference from Rule 80B to Rule 7.12. In connection with this 
change, the Exchange proposes to add a preamble to Rule 80B that would 
provide that ``[t]his Rule is not applicable to trading on the Pillar 
trading platform.''
Proposed Amendments to Rule 7.16 (Short Sales)
    When the Exchange added Rule 7.16, it designated specified 
subparagraphs of that rule as ``Reserved'' because at that time, the 
Exchange did not include rule text relating to Exchange-listed 
securities in Rule 7.16. For the transition of Exchange-listed 
securities to Pillar, the Exchange proposes to include text from Rule 
440B relating to Exchange-listed securities in those reserved sections 
of Rule 7.16.
    First, the Exchange proposes rule text from Rule 440B(c), relating 
to the Determination of Trigger Price, for Rule 7.16(f)(3) without any 
substantive differences. The Exchange proposes a non-substantive 
difference to refer to ``the Exchange'' rather than ``Exchange 
systems.'' Text from Rule 440B(c)(1) would be included in proposed Rule 
7.16(f)(3)(A) with a non-substantive difference to use Pillar 
terminology. Specifically, rather than the current rule, which uses the 
phrase ``until it opens trading for that security,'' the proposed rule 
would use the phrase ``until the Core Trading Session begins for that 
security.''
    Second, the Exchange proposes rule text from Rule 440B(d)(1) and 
(2), relating to circumstances when a Short Sale Price Test may be 
lifted, for proposed Rule 7.16(f)(4)(A) and (B) with only a non-
substantive difference to update the rule cross reference relating to 
clearly erroneous executions to Rule 7.10. The Exchange also proposes 
to amend Rule 7.16(f)(4) to add the term ``listing'' to conform it to 
Rule 440B(d) text.
    Finally, the Exchange proposes to that proposed Rule 7.16(f)(8), 
relating to single-priced opening, re-opening, and closing 
transactions, would be based on current Rule 440B(h) without any 
substantive differences. Specifically, in 2011, the Exchange received 
exemptive relief from Rule 201 of Regulation SHO for single-priced 
opening, reopening, and closing transactions, which relief is codified 
in Rule 440B(h).\93\ When Exchange-listed securities transition to 
Pillar, the manner by which auctions would be conducted under the 
Pillar Auction Rules will function in a substantially similar manner as 
under the Current Auction Rules, and therefore the reasons that serve 
as the basis for the exemptive relief would continue. Accordingly, the 
Exchange proposes to continue to operate consistent with Rule 
440B(h)(1)--(3) and the exemptive relief previously granted. To ensure 
continuity, proposed Rule 7.16(f)(8)(A)(i)--(iii), (B)(i)--(iii), and 
(C) is based on Rule 440B(h)(1)--(3), with only non-substantive 
differences to use Pillar terminology and to break the rule text down 
into multiple subparagraphs. The Exchange also proposes a non-
substantive difference to refer to ``the Exchange'' rather than 
``Exchange systems.'' The Exchange believes that the proposed non-
substantive differences will promote clarity in Exchange rules and make 
the text easier to navigate.

Commission, to Janet McGuinness, Senior Vice President and 
Secretary, NYSE Euronext dated (February 7, 2011), which is

---------------------------------------------------------------------------

Proposed Amendments to Rule 7.18 (Halts)
    Because the Exchange will be conducting Trading Halt Auctions in 
Exchange-listed securities, the Exchange proposes to amend Rule 7.18(c) 
to delete the ``Reserved'' designation and provide that the Exchange 
would process new and existing orders in securities listed on the 
Exchange during a halt or pause as follows:
     Cancel any unexecuted portion of Non-Displayed Limit 
Orders, Non-Displayed Primary Pegged Orders, MPL Orders, and proposed 
Floor broker cross transaction pending in the Cross Function pursuant 
to Rule 76.10 (see proposed Rule 7.18(c)(1)).\94\
---------------------------------------------------------------------------

    \94\ Currently, Floor brokers can effect proposed cross 
transactions in both Exchange-listed and UTP Securities pursuant to 
Rule 76. In addition, the Cross Function described in current Rule 
76.10 and the priority for specified block-sized cross transactions 
described in current Rule 72(d) are available for proposed cross 
transactions in Exchange-listed securities only. When Exchange-
listed securities transition to Pillar, the Exchange does not 
propose any differences to how these rules would function and 
therefore they will continue to be applicable to Floor broker cross 
transactions. The Exchange proposes to amend the preamble to Rule 72 
to specify that paragraph (d) and Supplementary Material .10 of that 
Rule would continue to be applicable to trading of Exchange-listed 
securities. The Exchange does not propose any changes to the 
preamble to Rule 76.

---------------------------------------------------------------------------

[[Page 6902]]

     Maintain any unexecuted quantity of Market Orders (see 
proposed Rule 7.18(c)(2)).
     Reprice all other resting orders in the Exchange Book to 
their limit price (see proposed Rule 7.18(c)(3)).
     Accept and process all cancellations (see proposed Rule 
7.18(c)(4)).
     Reject incoming Limit Orders designated IOC, Non-Displayed 
Limit Orders, Non-Displayed Primary Peg Orders, MPL Orders, and 
proposed Floor broker cross transactions pursuant to Rule 76.10 (see 
proposed Rule 7.18(c)(5)).
     Accept all other incoming order instructions until the 
Auction Processing Period for the Trading Halt Auction, at which point, 
Rule 7.35(e) (described above) would govern the entry of incoming 
orders and order instructions.
    This proposed rule text is based in part on NYSE Arca Rule 7.18-
E(c) and NYSE American Rule 7.18E(c), with certain differences. This 
proposed rule text is intended to mirror what order types and modifiers 
in Exchange-listed securities would be eligible to participate in a 
Trading Halt Auction: (1) Orders that are not eligible to trade in a 
Trading Halt Auction would be cancelled; (2) new orders that are not 
eligible to participate in an Auction would be rejected; (3) unexecuted 
Market Orders would be eligible to participate in the Trading Halt 
Auction; and (4) consistent with the proposal, above, orders 
participate in an Auction at their limit price and all other resting 
orders in the Exchange Book would be priced to their limit price. The 
Exchange would also continue to accept and process cancellations, and 
would continue with this order processing until the Auction Processing 
Period, at which time the order handling described in proposed Rule 
7.35(e) would begin.
Proposed Amendments to Rule 7.32 (Order Entry)
    On Pillar, orders entered that are greater than five million in 
shares in size are rejected.\95\ By contrast, pursuant to Rule 1000, 
for Exchange-listed securities only, orders up to 1,000,000 shares are 
eligible for automatic execution and incoming orders of more than 
1,000,000 shares that are marketable on arrival will be rejected. Upon 
advance notice to market participants, the Exchange may increase the 
order size eligible for automatic executions up to 5,000,000 shares on 
a security-by-security basis.\96\ When Exchange-listed securities 
transition to Pillar, they will be subject to the order entry size set 
forth in Rule 7.32 rather than the order entry size specified in the 
first paragraph of Rule 1000.
---------------------------------------------------------------------------

    \95\ See Rule 7.32.
    \96\ See Rule 1000.
---------------------------------------------------------------------------

    Rule 1000 requirements relating to maximum system order size 
accepted by Exchange systems are applicable to trading in both 
Exchange-listed securities and UTP Securities on Pillar and provide 
that the Exchange currently accepts a maximum order size of up to 
25,000,000 shares in size, i.e., for orders that are not eligible for 
automatic execution. This rule allows member organizations to enter MOC 
and LOC Orders, which are not eligible for automatic execution, up to 
25,000,000 shares in size. It also permits DMMs and Floor brokers to 
enter interest for auctions up to 25,000,000 shares in size and Floor 
brokers to enter cross transactions pursuant to Rule 76 up to 
25,000,000 shares in size. The current rule also provides that Floor 
broker systems shall accept a maximum order size of up to 99,000,000 
shares, which enables Floor brokers to accept larger-sized not held, 
parent orders from their customers.
    The Exchange proposes to amend Rule 7.32 to reflect the maximum 
order size that Exchange systems will accept in specified 
circumstances, consistent with Rule 1000. As proposed, in Auction-
Eligible Securities, the Exchange would accept orders defined in Rule 
7.31(c),\97\ DMM Auction Liquidity as defined in Rule 7.35, and Floor 
Broker Interest intended for the Closing Auction as defined in Rule 
7.35B(a)(1) up to 25 million shares in size. The Exchange further 
proposes to provide that in all securities traded on the Exchange, the 
Exchange would accept proposed cross transactions under Rule 76 up to 
25 million shares in size. This proposed rule text would address the 
same order-entry scenarios contemplated in Rule 1000 (i.e., orders that 
are not eligible for automatic execution) without any substantive 
differences. The Exchange proposes non-substantive differences to use 
Pillar terminology to specify the specific order types that would be 
eligible for this larger entry size.
---------------------------------------------------------------------------

    \97\ As described above, Rule 7.31(c) specifies the Auction-Only 
Orders available on the Exchange. Consistent with current 
functionality, in Auction-Eligible Securities, the Exchange would 
accept Auction-Only Orders up to 25,000,000 million shares in size.
---------------------------------------------------------------------------

    The Exchange also proposes to amend Rule 7.32 to provide that Floor 
broker systems would accept a maximum order size up to 99 million 
shares. This proposed rule text is based on the last sentence of the 
second paragraph of Rule 1000 without any substantive differences.
Proposed Amendments to Rule 7.34 (Trading Sessions)
    Pursuant to Rule 7.34, UTP Securities trading on Pillar are 
eligible to trade in the Early Trading Session, which begins at 7:00 
a.m. By contrast, pursuant to Rule 51, the hours of trading for 
Exchange-listed securities begins at 9:30 a.m. When the Exchange 
transitions Exchange-listed securities to Pillar, it proposes to 
maintain that such securities would be eligible to trade in the Core 
Trading Session only. The Exchange proposes to amend Rule 7.34(a) to 
specify the distinction between which securities would be eligible to 
trade in each session.
    First, the Exchange proposes to amend Rule 7.34(a)(1) to provide 
that only UTP Securities are eligible to trade in the Early Trading 
Session. Consistent with current practice, the Exchange would begin 
accepting orders in all securities at the same time. Accordingly, the 
Exchange proposes to further amend Rule 7.34(a)(1) to provide that the 
Exchange would begin accepting orders in all securities 30 minutes 
before the Early Trading Session begins.
    Second, the Exchange proposes to amend Rule 7.34(a)(2) to provide 
that all securities traded on the Exchange would be eligible to trade 
in the Core Trading Session. The Exchange further proposes to move the 
current text to new subparagraph (A), which would continue to provide 
that the Core Trading Session will begin for each security at 9:30 a.m. 
and end at the conclusion of Core Trading Hours. Proposed Rule 
7.34(a)(2)(A) would further provide that this text would be applicable 
to UTP Securities only.
    Proposed Rule 7.34(a)(2)(B) would be new and would address 
Exchange-listed securities. As proposed, for Exchange-listed 
securities, the Core Trading Session would begin with the Core Open 
Auction, which can take place during Core Trading Hours only, and would 
end for each security at the later of the conclusion of Core Trading 
Hours or, if a Closing Auction is conducted, the Closing Auction. This 
proposed rule text reflects how trading in Exchange-listed securities 
currently functions

[[Page 6903]]

under Rules 51, 52, and Rule 123C: Such securities are not eligible to 
begin trading until 9:30 a.m. and all bids and offers must be made by 
4:00 p.m. The proposed rule text uses Pillar terminology to reflect 
these current requirements.
    The Exchange further proposes that Rule 7.34(a)(2)(B) would provide 
that, except as provided for in Rules 7.35B(a)(1) and (2) and (j)(2), 
all order instructions must be entered by the end of Core Trading Hours 
and bids and offers represented orally by a Floor broker must be 
represented at the point of sale by the end of Core Trading Hours. This 
proposed rule text is based on Rule 52, which provides that dealings on 
the Exchange shall be limited to the hours during which the Exchange is 
open for the transaction of business, which is currently described in 
Rule 51. Rule 52 further provides that no member shall make any bid, 
offer, or transaction on the Exchange before or after those hours.\98\ 
As described above, proposed Rules 7.35B(a)(1) and (2) describe how 
Floor Broker Interest and DMM Interest can be entered for the Closing 
Auction, including the manner by which Floor Broker Interest is 
electronically entered into Exchange systems for participation in the 
Closing Auction. Proposed Rule 7.35B(j)(2)(A) provides for a temporary 
suspension of the requirement for order instructions to be entered by 
the end of Core Trading Hours (which, under the Current Auction Rules, 
is a temporary suspension of Rule 52), and proposed Rule 7.35B(j)(2)(B) 
provides for a temporary suspension of the prohibition of cancelling a 
MOC or LOC Order after two minutes before the scheduled end of Core 
Trading Hours.
---------------------------------------------------------------------------

    \98\ The reference to the term ``member'' in Rule 52 refers to a 
natural person associated with a member organization who has been 
approved by the Exchange and designated by such member organization 
to effect transactions on the Floor of the Exchange, i.e., a Floor 
broker or DMM. See Rule 2(a).
---------------------------------------------------------------------------

    Third, the Exchange proposes to amend Rule 7.34(b)(1) to reflect 
how orders would be deemed designated. Consistent with existing 
functionality that UTP Securities are eligible to trade in both the 
Early and Core Trading Sessions, the Exchange proposes to amend current 
Rule 7.34(b)(1), which provides that unless otherwise specified in Rule 
7.34(c), an order entered before or during the Early or Core Trading 
Session will be deemed designated for the Early Trading Session and the 
Core Trading Session, to specify that this rule pertains to orders in 
UTP Securities only. The Exchange further proposes to amend Rule 
7.34(b)(1) to add that all orders in Exchange-listed securities would 
be deemed designated for the Core Trading Session only. This proposed 
rule text uses Pillar terminology to reflect current functionality.
    Finally, the Exchange proposes new Rule 7.34(c)(1)(D) to specify 
that Non-Displayed Limit Orders, MPL Orders, Limit Orders designated 
IOC, and proposed Floor broker cross transactions pursuant to Rule 
76.10 in Auction-Eligible Securities would be rejected if entered 
before the Core Trading Session begins. As noted above, these order 
types in Auction-Eligible Securities would not be eligible to 
participate in the Core Open Auction and based on proposed Rule 
7.18(c)(5), would be rejected if entered during a halt or pause. For 
similar reasons, the Exchange proposes to reject such orders if entered 
before the Core Trading Session begins.\99\ In addition, currently, the 
Exchange does not accept proposed Floor broker cross transactions 
pursuant to Rule 76.10 until a security has opened for trading. 
Accordingly, the proposed rule text uses Pillar terminology to describe 
this functionality.
---------------------------------------------------------------------------

    \99\ Rule 7.34(c)(1)(A) already provides that Non-Displayed 
Primary Pegged Orders would be rejected if entered before the Core 
Trading Session and this rule text is applicable to such orders in 
both UTP Securities and Auction-Eligible Securities.
---------------------------------------------------------------------------

Proposed Amendment to Rule 7.36 (Order Ranking and Display)
    As described above, the Exchange proposes to amend Rule 7.36(a) to 
add the DMM Participant. The Exchange also proposes to amend Rule 
7.36(h) to specify in new subparagraph (5) that Setter Priority would 
not be available for any allocations in an Auction. This proposed rule 
text is based on how Rule 72(a)(ii), which describes setter interest, 
functions for Exchange-listed securities today. Specifically, as 
provided for in Rule 72(b), once priority is established by setting 
interest, setting interest retains priority for any execution at that 
price when that price is at the Exchange BBO. Because an auction is a 
single-priced transaction, which is not considered an execution at the 
Exchange BBO, currently, setter interest allocations are not available 
for auction allocations. Accordingly, proposed Rule 7.36(h)(5) would 
use Pillar terminology to describe current functionality, which would 
not be changing.
2. Statutory Basis
    The Exchange believes that the proposal is consistent with Section 
6(b) of the Act,\100\ in general, and furthers the objectives of 
Sections 6(b)(5) of the Act,\101\ in particular, because it is designed 
to prevent fraudulent and manipulative acts and practices, to promote 
just and equitable principles of trade, to foster cooperation and 
coordination with persons engaged in regulating, clearing, settling, 
processing information with respect to, and facilitating transactions 
in securities, to remove impediments to, and perfect the mechanisms of, 
a free and open market and a national market system and, in general, to 
protect investors and the public interest and because it is not 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.
---------------------------------------------------------------------------

    \100\ 15 U.S.C. 78f(b).
    \101\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    Definitions. The Exchange believes that the proposed amendments to 
Rule 1.1 would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because they would 
add definitions to the Pillar Platform Rules to support the transition 
of Exchange-listed securities to Pillar, including those relating to 
DMMs, IPOs, and Direct Listings. These proposed definitions are not new 
and reflect current functionality and definitions. The Exchange 
believes that the proposed definition of Official Closing Price, which 
is based on the NYSE Arca and NYSE American version of this definition 
rather than the current Exchange version of this definition, would 
remove impediments and perfect the mechanism of a free and open market 
and a national market system because it would provide for a 
standardized methodology for determining the Official Closing Price 
across affiliated exchanges, thereby promoting consistency in Exchange 
rules for how such price would be determined.
    DMM Participant. The Exchange believes that the proposed amendments 
to Rules 7.36 and 7.37 to add the DMM as a Participant for the purpose 
of how executions are allocated would remove impediments to and perfect 
the mechanism of a free and open market and a national market system 
because it would facilitate the transition of Exchange-listed 
securities to the Pillar platform. Pursuant to Rule 103B, all 
securities listed on the Exchange are assigned to a DMM and pursuant to 
Rule 104, DMMs have specified affirmative responsibilities with respect 
to their assigned securities. These obligations are not changing when 
Exchange-listed securities transition to Pillar. The proposed 
amendments would describe how DMMs would

[[Page 6904]]

participate in the allocation of executions in their assigned 
securities on Pillar consistent with the existing parity allocation 
model described in Rule 7.37(b). The Exchange does not propose any 
substantive differences to how a DMM would participate in an allocation 
on Pillar as compared to how a DMM currently participates in an 
allocation under Rule 72(c).
    Auction-Only Orders. The Exchange believes that the proposed 
changes to Rule 7.31 relating to Auction-Only Orders would remove 
impediments to, and perfect the mechanisms of, a free and open market 
and a national market system and, in general, protect investors and the 
public interest by introducing on Pillar existing order types currently 
available for trading of Exchange-listed securities. As noted above, 
currently, the Exchange trades only UTP Securities on Pillar. To 
facilitate the transition of Exchange-listed securities to Pillar, the 
Exchange proposes to amend Rule 7.31(c) to expand the Auction-Only 
Orders available on Pillar to include order types currently available 
on the Exchange.
    The Exchange believes that amending the descriptions of existing 
order types on Pillar--LOOs, MOOs, LOCs, and MOCs--would remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system by providing transparency regarding how such 
orders would function depending on whether such order would be for a 
UTP Security or an Auction-Eligible Security. As is the case today, 
LOOs, MOOs, LOCs, and MOCs in UTP Securities would be routed to the 
primary listing exchange for that security. And as is the case today 
for Exchange-listed securities, these same orders in Exchange-listed 
securities would participate in auctions on the Exchange.
    The proposed Opening and Closing D Orders, which the Exchange now 
proposes to define separately under Auction-Only Orders in the Pillar 
rules, are based on existing d-Quote functionality as described in Rule 
70.25(a)(ii). The Exchange believes that these proposed order types 
would remove impediments to and perfect the mechanisms of a free and 
open market and a national market system because they would ensure 
continuity of order types that would be available when Exchange-listed 
securities transition to Pillar. The proposed differences between these 
orders and d-Quote functionality are largely non-substantive to provide 
additional transparency regarding how such orders would function on 
Pillar. Like d-Quotes, an Opening or Closing D Order in an Exchange-
listed security would be available to Floor brokers only and would be 
triggered to exercise discretion only in an auction. For example, a 
Closing D Order entered prior to the Closing Auction would function as 
a Limit Order and would be eligible for execution or routing based on 
its limit price during continuous trading. The Exchange notes that the 
proposed Opening and Closing D Orders would not have any execution 
priority compared to other orders trading in an auction. Today, all 
better-priced orders are guaranteed to participate in an auction, and 
the Exchange proposes to maintain that auction logic when it 
transitions to Pillar. If the discretionary price of an Opening or 
Closing D Order were better-priced than the price of the auction, it 
would participate in that auction just as any other better-priced order 
would participate in such auction. Therefore, the proposed Opening and 
Closing D Orders do not present any new or novel issues.
    The Exchange further believes that the proposed difference from d-
Quotes to reject both the entry and cancellation of Closing D Orders 
that are entered ten seconds or less before the scheduled time for the 
Closing Auction would remove impediments to and perfect the mechanism 
of a free and open market and a national market system by promoting 
transparency and would also promote fair and orderly auctions by 
reducing the potential for a Closing D Order to be changed leading into 
the close.
    Finally, the Exchange believes that the proposed Closing IO Order 
would remove impediments to and perfect the mechanism of a free and 
open market and a national market system because it is based on the CO 
Order described under Rule 13(c)(1), which is currently available for 
Exchange-listed securities. The Exchange similarly proposes to offer 
the Closing IO Order for Exchange-listed securities on Pillar and such 
order type would ensure continuity in what auction orders would be 
available for when the Exchange transitions trading of Exchange-listed 
securities to Pillar.
    Order Eligibility for Auctions. The Exchange believes that the 
proposed amendments to Rule 7.31 to specify which orders and modifiers 
would not be eligible to participate in an auction would remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system because it would promote transparency in 
Exchange rules regarding which orders are not auction eligible. With 
two exceptions, the proposed rules are based on how the Exchange 
currently functions, as described in current rules. The Exchange 
proposes a substantive difference that orders with an IOC time-in-force 
designation would not be eligible to participate in an auction. The 
Exchange believes that this proposed difference would be consistent 
with the terms of such orders, which requires them to be cancelled if 
not immediately executable. In addition, this proposed difference is 
based on the rules of NYSE Arca and NYSE American.
    The second substantive difference concerns the treatment of Primary 
Pegged Orders, which would not be eligible to participate in the 
Closing Auction. The Exchange believes that this proposed difference 
would remove impediments to and perfect the mechanism of a free and 
open market and a national market system by streamlining order 
processing. Specifically, because orders would participate in a Closing 
Auction at their limit price and because Primary Pegged Orders are 
pegged to the same-side PBBO and are not displayed at their limit 
price, the Exchange believes that this proposed difference would reduce 
the number of orders that would need to be repriced in order to 
participate in the Closing Auction.
    Limit Order Price Protection. The Exchange believes that the 
proposed amendments to Rule 7.31(a)(2)(B) relating to Limit Order Price 
Protection would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because Limit Order 
Price Protection is designed to reject Limit Orders that are priced too 
far away from the prevailing NBBO. On the Exchange, if the first 
opportunity for an order on the Exchange to trade is in an Auction, 
these considerations are not applicable because such orders would 
execute in the Auction at the Auction Price, and not the limit price of 
the order. For similar reasons, because the first opportunity for Floor 
Broker Interest, DMM Interest entered after 4:00 p.m. for the Closing 
Auction, and orders solicited pursuant to proposed Rule 7.35B(j)(2)(A) 
to trade would be the Closing Auction, the Exchange believes that it 
would promote just and equitable principles of trade and remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system for these orders not to be subject to Limit 
Order Price Protection.
    Proposed Rule 7.35 Series. The Exchange believes that the proposed 
Rule 7.35 Series would remove impediments to and perfect the mechanism 
of a free and open market and a national market system because it

[[Page 6905]]

would consolidate rules governing Auctions on the Exchange in one 
location in the rulebook. As discussed in detail above, the proposed 
Pillar Auction Rules, which are set forth in the Rule 7.35 Series, are 
largely based on the Current Auction Rules. More specifically, and as 
discussed in greater detail above, when Exchange-listed securities 
transition to Pillar, the manner by which Auctions will be conducted on 
the Exchange will function substantially the same as how they currently 
function under the Current Auction Rules. For example, DMMs will 
continue to be primarily responsible for facilitating Auctions on the 
Exchange, the Exchange will continue to disseminate the same 
information in connection with Auctions, and the manner by which shares 
will be allocated in an Auction will be the same.
    While functionality would be substantially the same, in contrast to 
the Current Auction Rules, the proposed Rule 7.35 Series describe 
Auctions in sequential rules. In addition, in contrast to the Current 
Auction Rules, the proposed Rule 7.35 Series would use consistent 
Pillar terminology to describe functionality that is common to all 
Auctions. In addition, the proposed rule numbering is aligned with the 
rule numbers used by NYSE Arca and NYSE American regarding auctions on 
those exchanges, thereby promoting consistency across affiliated 
exchanges regarding how to navigate their respective rulebooks.
    The Exchange further believes that the proposed structure of the 
Rule 7.35 Series would remove impediments to and perfect the mechanism 
of a free and open market and a national market system because it is 
designed to consolidate those rules that are applicable to any Auction 
in proposed Rule 7.35 (General). By consolidating functionality that 
would be applicable to all Auctions on the Exchange in Rule 7.35, 
including definitions, auction ranking, Auction Imbalance Information, 
openings and reopenings in the last ten minutes of trading, order 
processing during an Auction Processing Period, transition to 
continuous trading following an Auction, and Auction functions during a 
Short Sale Period, the Exchange believes that its rules would be easier 
to navigate. This proposed structure would also reduce the need for 
duplication in its rules.
    The Exchange believes that proposed Rule 7.35A would remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system because that rule would use Pillar terminology 
to describe how DMM-facilitated Core Open and Trading Halt Auctions 
would function. By contrast, under the Current Auction Rules, this 
functionality is described in Rules 15, 115A, and 123D. For similar 
reasons, the Exchange believes that proposed Rule 7.35B would remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system because that rule would use Pillar terminology 
to describe how DMM-facilitated Closing Auctions would function. In 
addition, proposed Rule 7.35B would use, where feasible, parallel 
subparagraph numbering as proposed Rule 7.35A. The Exchange believes 
that the proposed structure of Rules 7.35A and 7.35B is designed to 
make those rules easier to navigate.
    To the extent that the Pillar Auction Rules use Pillar terminology 
to describe current auction functionality, the Exchange believes that 
the proposed Pillar Auction Rules would promote just and equitable 
principles of trade and would remove impediments to and perfect the 
mechanism of a free and open market and a national market system 
because these rules would not result in any changes to how auctions 
function on the Exchange. Rather, the proposed Pillar Auction Rules 
would allow for the continued, uninterrupted operation of auctions when 
Exchange-listed securities transition to Pillar while at the same time 
updating the rule text to use consistent terminology.
    As described in detail above, in the move to Pillar, the Exchange 
has identified a number of enhancements to how auctions would function 
on the Exchange that would result in a substantive difference from the 
Current Auction Rules. The Exchange believes that these substantive 
differences are consistent with the Act for the following reasons:
     The Exchange believes that using the Consolidated Last 
Sale price as the basis for various reference prices for openings and 
reopenings and the Exchange Last Sale Price as the basis for various 
reference prices for closings would remove impediments to and perfect 
the mechanism of a free and open market because, as described in detail 
above, use of these proposed reference prices is designed, for the most 
part, to use the same reference price as under the Current Auction 
Rules. However, there would be specified circumstances when the Pillar 
Auction Rule reference price would be different from Current Auction 
Rules, and the Exchange believes that those differences would allow for 
the Exchange to use the most recent valuation for purposes of assessing 
price movement leading into an Auction. For example, the use of the 
term Consolidated Last Sale Price would incorporate consolidated last-
sale eligible trades after 9:30, and if none, the Official Closing 
Price of a security, for purposes of providing guidance to the DMM and 
determining the Imbalance Reference Price for opening or reopening 
security. And for the Closing Auction, use of the Exchange Last Sale 
Price would incorporate the Official Closing Price as a reference price 
if there are no trades on the Exchange on a trading day, which would be 
new.
     The Exchange believes that updating Auction Imbalance 
Information, which is made available over the Exchange's proprietary 
data feeds, every second rather than in five-minute, one-minute, or 
five-second intervals as under the Current Auction Rules, and beginning 
the dissemination of Auction Imbalance Information for the Core Open 
Auction at 8:00 a.m. rather than 8:30 a.m., would remove impediments to 
and perfect the mechanism of a free and open market and a national 
market system because it would promote transparency regarding the 
auction process at the Exchange. These proposed changes are also based 
on the approved rules of NYSE Arca and NYSE American. The Exchange 
further believes that continuing to disseminate Auction Imbalance 
Information for the Closing Auction until such Auction is conducted 
would similarly remove impediments to and perfect the mechanism of a 
free and open market and a national market system because it would 
promote transparency leading into the Closing Auction, particularly 
when Floor Broker Interest is incorporated into that information.
     The Exchange believes that specifying that the reference 
price used for determining whether to publish a pre-opening indication 
for securities that have limited publicly-available pricing information 
available would be a price as determined under proposed Rule 
1.1(s)(1)(F) would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because it would 
incorporate an existing price into rules relating to pre-opening 
indications. The reference price used by the DMM to determine whether 
to publish a pre-opening indication is not a publicly-disclosed price. 
Rather, DMMs use that reference price as a benchmark to determine 
whether to publish a pre-opening indication. The actual pre-opening 
indication price range that is disseminated publicly is

[[Page 6906]]

based on what the DMM anticipates the opening price would be, based on 
orders in the Exchange Book as well as the DMM's own liquidity. 
Currently, pursuant to Rule 123C(1)(e)(i)(C), the Exchange already 
determines a price for such securities that is a derived last sale 
price, and, as described above, that current rule will be set forth in 
proposed Rule 1.1(s)(1)(F), unchanged. The Exchange believes that using 
this existing price for purposes of determining whether to publish a 
pre-opening indication would promote transparency in Exchange rules 
regarding what guidance the DMM would have for whether to publish a 
pre-opening indication for a new listing that is not otherwise 
addressed in proposed Rule 7.35A(d)(2)(A)(i)-(iv).
     The Exchange believes that the proposed changes to how 
Floor Broker Interest would be entered into Exchange systems for 
participation in the Closing Auction would remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system because it would reduce the burden on the DMM to electronically 
enter orders on behalf of Floor brokers, thereby leading to a more 
efficient closing process. As described above, as under Current Auction 
Rules, Floor Broker Interest intended for the Closing Auction must be 
orally represented by the end of Core Trading Hours. The proposed 
difference involves a processing enhancement under Pillar whereby the 
Floor broker, rather than the DMM, would electronically enter such 
previously-represented oral interest after 4:00 p.m. so that it may be 
processed as part of the Closing Auction. The DMM would still be 
responsible for validating such Floor Broker Interest by being required 
to accept such electronic submission before the interest would be 
ranked and eligible for the Closing Auction and included in the Auction 
Imbalance Information. The Exchange believes that this requirement 
would promote just and equitable principles of trade as it would serve 
as a validation that such interest was properly represented orally by 
the end of, but not after, Core Trading Hours.
     The Exchange believes that the proposed substantive 
difference that Floor Broker Interest for the Closing Auction must 
include a limit price and would be processed as part of the Auction 
allocation the same as any other order with a limit price would promote 
just and equitable principles of trade and remove impediments to and 
perfect the mechanism of a free and open market and a national market 
system because it would standardize the processing of orders with a 
limit price in the Closing Auction and would eliminate any differences 
of how interest represented orally at the close by a Floor broker would 
be processed as compared to electronically-entered orders.
     The Exchange believes that it would remove impediments and 
perfect the mechanism of a free and open market and a national market 
system to disseminate a Regulatory Closing Imbalance, if required, at 
the Closing Auction Imbalance Freeze Time, regardless of whether a 
security is halted at that time. The Exchange believes that this 
proposed difference from the Current Auction Rules would streamline 
functions leading into the close. It would also permit the entry of 
offsetting MOC and LOC Orders during a trading halt that continues past 
the Closing Auction Imbalance Freeze Time if a Regulatory Closing 
Imbalance is disseminated.
     The Exchange believes that the proposed change that during 
a halt or pause in Exchange-listed securities, orders not eligible to 
participate in the reopening would be cancelled rather than kept on the 
Exchange Book, would remove impediments to and perfect the mechanism of 
a free and open market and a national market system because it would 
streamline order processing for when trading resumes in that security.
     The Exchange believes that proposed Rule 7.35C would 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system because it is based in part on how 
the Exchange would currently facilitate an Auction if the DMM were not 
available, including that such auctions would continue to be subject to 
price limitations and not all orders would be guaranteed to 
participate, as provided for under the Current Auction Rules. The 
Exchange believes that the proposed enhancements as compared to the 
Current Auction Rules would promote just and equitable principles of 
trade because they are based in part on functionality currently 
available for electronic auctions on NYSE Arca and NYSE American, 
including pricing an auction based on an Indicative Match Price that is 
subject to Auction Collars. Because the Exchange calculates Auction 
Imbalance Information differently from NYSE Arca and NYSE American, the 
Exchange believes that the proposed difference from NYSE Arca and NYSE 
American to use the Imbalance Reference Price as the Auction Reference 
Price would promote consistency in how the Exchange determines whether 
there is an Imbalance for an Auction, regardless of whether the Auction 
would be facilitated by a DMM or by the Exchange. The Exchange further 
believes that the proposed Auction Collars would promote just and 
equitable principles of trade because they would only be used if the 
Exchange were to facilitate an Auction, which is available as a 
business continuity measure for the remote possibility of a DMM being 
unavailable. The Exchange further believes that applying extension 
logic for reopenings after a Trading Pause would promote just and 
equitable principles of trade and remove impediments to and perfect the 
mechanism of a free and open market and a national market system 
because it would align the rules of the Exchange with those of NYSE 
Arca and NYSE American with respect to extension logic that would be 
applicable for an electronic reopening auction following a Trading 
Pause.
    Rule 7.11. The Exchange believes that the proposed amendments to 
Rule 7.11 would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because they would 
update the rule to support the trading of Exchange-listed securities 
and the Exchange's role as primary listing exchange for such 
securities. The proposed amendments are based on the rules of NYSE Arca 
and NYSE American with minor differences to include NYSE rule cross 
references.
    Rule 7.12. The Exchange believes that proposed Rule 7.12 would 
remove impediments to and perfect the mechanism of a free and open 
market and a national market system because it is substantially 
identical to Rule 80B. The only proposed differences from Rule 80B are 
the cross references to Pillar Auction Rules rather than the Current 
Auction Rules. The Exchange believes that using rule numbering that is 
aligned with the rule numbers of NYSE Arca and NYSE American would 
promote consistency in the rule books of affiliated exchanges, making 
the rules easier to navigate for common members.
    Rule 7.16. The Exchange believes that the proposed amendments to 
Rule 7.16 would remove impediments to and perfect the mechanism of a 
free and open market and national market system because it would move 
existing Exchange text from Rule 440B to the Pillar rule governing 
short sales without any substantive differences. The Exchange further 
believes that the proposed non-substantive differences to use Pillar 
terminology would promote transparency in Exchange rules by using 
consistent terminology.

[[Page 6907]]

    Rule 7.18. The Exchange believes that the proposed amendment to 
Rule 7.18 to add subparagraph (c) relating to how the Exchange would 
process new and existing orders listing on the Exchange during a halt 
or pause would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because it would 
promote transparency in Exchange rules regarding processing of orders 
during a halt or pause. The Exchange further believes that the proposed 
amendments would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because it would 
streamline order processing during a halt or pause to cancel resting 
orders and reject new orders in Auction-Eligible Securities that are 
not eligible to participate in a Trading Halt Auction.
    Rule 7.32. The Exchange believes that the proposed amendments to 
Rule 7.32 would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because it would 
include in the Exchange's Pillar rules existing functionality relating 
to order entry size. The Exchange believes that the proposed non-
substantive differences from Rule 1000 would promote consistency in 
Exchange rules by using Pillar terminology.
    Rule 7.34. The Exchange believes that the proposed amendments to 
Rule 7.34 would remove impediments to and perfect the mechanism of a 
free and open market and a national market system because they are 
designed to support the transition of Exchange-listed securities to 
Pillar. The Exchange does not propose any substantive differences, 
because the hours of trading Exchange-listed securities would not be 
changing. The Exchange further believes that the proposed amendments 
would promote transparency in Exchange rules by specifying the 
difference in hours of trading Exchange-listed securities and UTP 
Securities. The Exchange further believes that proposed Rule 
7.34(c)(1)(D) would remove impediments to and perfect the mechanism of 
a free and open market and a national market system because rejecting 
orders in Auction-Eligible Securities that are not eligible to 
participate in the Core Open Auction would streamline order processing 
for when the Exchange transitions to continuous trading.
    Preambles. The Exchange believes the proposed amendments to the 
preambles to current Exchange rules and new preambles would remove 
impediments to and perfect the mechanism of a free and open market and 
a national market system because they would promote transparency in 
Exchange rules regarding whether a rule would be applicable to trading 
of securities on Pillar.

B. Self-Regulatory Organization's Statement on Burden on Competition

    In accordance with Section 6(b)(8) of the Act,\102\ the Exchange 
believes that the proposed rule change would not impose any burden on 
competition that is not necessary or appropriate in furtherance of the 
purposes of the Act. The proposed rule change is not designed to 
address any specific competitive issues and instead supports the 
transition of Exchange-listed securities to the Exchange's Pillar 
trading platform. As described in detail above, the proposed rule 
changes are substantially based on how the Exchange currently functions 
for its Exchange-listed securities. Accordingly, to the extent that the 
Exchange's current market model for trading of its Exchange-listed 
securities, which features DMM-facilitated auctions and a parity 
allocation model with the DMM as an individual participant, is a 
competitive offering as compared to how other equity exchanges 
function, the proposed rule changes are designed simply to enable the 
Exchange to continue with this existing market model when it 
transitions Exchange-listed securities to the Pillar trading platform.

    \102\ 15 U.S.C. 78f(b)(8).
---------------------------------------------------------------------------

    The Exchange further believes that the proposed substantive 
differences to how auctions would function on the Exchange on Pillar 
are not designed for competitive reasons, but rather to apply certain 
existing Pillar features that are already available on NYSE Arca and 
NYSE American to auctions on the Exchange. The Exchange believes that 
these features would streamline operations on the Exchange. The 
Exchange operates in a highly competitive environment in which its 
unaffiliated exchange competitors operate under common rules for the 
trading of securities listed on their markets.
