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

    Cboe EDGX Exchange, Inc. (the ``Exchange'' or ``EDGX'') proposes to 
amend its automated price improvement auction rules. The text of the 
proposed rule change is provided in Exhibit 5.
    The text of the proposed rule change is also available on the 
Exchange's website (http://markets.cboe.com/us/options/regulation/rule_filings/edgx/), at the Exchange's Office of the Secretary, 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 Exchange 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 these 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 aspects of such 
statements.

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

1. Purpose
    The Exchange proposes to amend Rule 21.19 (Automated Price 
Improvement Mechanism (``AIM'' or ``AIM Auction'')) and Rule 21.22 
(Complex Automated Improvement Mechanism (``C-AIM'' or ``C-AIM 
Auction'')) to modify the stop price requirements for auto-match orders 
submitted to AIM and C-AIM, respectively.
    By way of background, Rules 21.19 and 21.22 contain the 
requirements applicable to the execution of orders using AIM and C-AIM, 
respectively. The AIM and C-AIM auctions are electronic auctions 
intended to provide an Agency Order with the opportunity to receive 
price improvement (over the National Best Bid or Offer (``NBBO'') in 
AIM, or the synthetic best bid or offer (``SBBO'') on the Exchange in 
C-AIM. Upon submitting an Agency Order into an AIM or C-AIM auction, 
the initiating Member (``Initiating Member'') must also submit a 
contra-side second order (``Initiating Order'') for the same size as 
the Agency Order. The Initiating Order guarantees that the Agency Order 
will receive an execution at no worse than the auction price (i.e., 
acts as a stop). During an AIM or C-AIM Auction, market participants 
submit responses to trade against the Agency Order. At the end of an 
auction, depending on the contra-side interest available, the contra 
order may be allocated a certain percentage of the Agency Order.\5\
---------------------------------------------------------------------------

    \5\ See generally Rules 21.19(e) and 21.22(e).
---------------------------------------------------------------------------

    An Initiating Member may initiate an AIM or C-AIM auction provided 
that the Agency Order is in a class and of sufficient size as 
determined by the Exchange. Further, there are requirements regarding 
the price at which the Initiating Order must stop the entire Agency 
Order, set forth in Rule 21.19(b) for AIM Auctions and Rule 21.22(b) 
for C-AIM Auctions. Requirements for the stop price depend on the order 
submitted, but in general, the stop price must be either better than 
the then-current NBBO (SBBO) or, in some cases, at or better than the 
NBBO (SBBO).\6\
---------------------------------------------------------------------------

    \6\ See generally Rules 21.19(b) and 21.22(b).
---------------------------------------------------------------------------

    Further, under Rules 21.19(b)(4) and 21.22(b)(4), an Initiating 
Member, in entering the contra-side order, must either (1) specify a 
single price at which

[[Page 41702]]

it seeks to execute the Agency Order against the Initiating Order, or 
(2) specify an initial stop price and instruction to automatically 
match the price and size of all AIM or C-AIM responses and other 
contra-side trading interest (``auto-match'') at each price up to a 
designated limit price or at all prices that improve the stop price. 
Currently, the System will reject or cancel both an Agency Order and 
Initiating Order submitted to an AIM or C-AIM Auction that does meet 
the eligibility requirements set forth in Rules 21.19(a) and 21.22(a), 
and the stop price requirements set forth in Rules 21.19(b) and 
21.22(b).
    The Exchange now proposes to amend Rule 21.19(b)(4) to state that, 
notwithstanding Rule 21.19(b)(1) through (3), if the initial stop price 
is worse than the then-current NBO (NBB) and auto-match was selected, 
the System changes the initial stop price for the Agency Order to be 
the then-current NBO (NBB) (or one minimum increment better than the 
then-current NBO (NBB) if the Agency Order is subject to the 
requirements set forth in Rules 21.19(b)(1)(A) or (b)(2). Similarly, 
the Exchange proposes to amend Rule 21.22(b)(4) to state that, 
notwithstanding Rule 21.22(b)(1) through (3), if the initial stop price 
is worse than the then-current SBO (SBB) and auto-match was selected, 
the System changes the initial stop price for the Agency Order to be 
the then-current SBO (SBB) (or one minimum increment better than the 
then-current SBO (SBB) if the Agency Order is subject to the 
requirements set forth in Rules 21.22(b)(1)(A), (b)(2), or (b)(3)(A). 
Under the proposed changes, the starting price (i.e., stop price) of 
the auction would match the NBBO (for AIM Auctions) or SBBO (for C-AIM 
Auctions) at the time of auction commencement. The proposed changes 
would apply to all AIM and C-AIM users that select auto-match.
    This change is designed to address situations where the NBBO or 
SBBO changes within the time that the User sends the order to the 
Exchange and the Exchange receives it, which may cause AIM and C-AIM 
orders to be cancelled. For example, assume a Member submits to AIM 
Auction an Agency Order to buy and an Initiating Order with a starting 
price of 1.25 and an auto-match limit of 1.10, and the then-current 
NBBO is 1.00-1.25. While in transit, the NBBO changes to 0.90-1.10. 
Under the current rules, the orders would be rejected, as the starting 
price (initial stop price) of 1.25 is now outside the current NBBO 
(even though the firm has designated an auto-match limit of 1.10, which 
is equal to the NBBO at the time the Exchange receives the order). 
Under the proposed rule, the orders would be accepted, and the auction 
starting price will be 1.10 (due to the NBBO change), and the auction 
would proceed pursuant to the remainder of the Rule.
2. Statutory Basis
    The Exchange believes the proposed rule change is consistent with 
the Securities Exchange Act of 1934 (the ``Act'') and the rules and 
regulations thereunder applicable to the Exchange and, in particular, 
the requirements of Section 6(b) of the Act.\7\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \8\ requirements that the rules of an exchange be 
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 
mechanism of a free and open market and a national market system, and, 
in general, to protect investors and the public interest. Additionally, 
the Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \9\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.

    \9\ Id.
---------------------------------------------------------------------------

    The Exchange believes the proposed rule change will promote just 
and equitable principles of trade and protect investors. In particular, 
the Exchange believes that its proposal to allow an order with an 
initial stop price inferior to the then-current NBBO or SBBO to be 
submitted to AIM or C-AIM Auction if auto-match is selected will 
provide Agency Orders with additional opportunities for price 
improvement and execution. Specifically, the changes are designed to 
stop orders from being rejected from AIM and C-AIM Auctions in 
situations where an order may have an initial stop price that is 
inferior to the then-current NBBO or SBBO, despite the fact that the 
Initiating Member has, through its auto-match selection, demonstrated a 
willingness to execute against the Agency Order at a price that matches 
or improves upon the then-current NBBO or SBBO, as applicable. The 
Exchange believes the changes are consistent with the intended result 
of the stop price requirement, as the Initiating Member is effectively 
guaranteeing that the Agency Order will receive an execution at no 
worse than the auction price, which is at or better than the NBBO at 
the time the auction begins, via the auto-match mechanism.\10\ As such, 
the Exchange believes the changes will preserve the quality of the 
auctions, while providing increased execution and price improvement 
opportunities for Agency Orders, which helps to perfect the mechanism 
of a free and open market and, in general, helps to protect investors 
and the public interest.\11\
---------------------------------------------------------------------------

    \10\ Note, the proposed rule change continues to provide price 
improvement assurances for those for buy (sell) Agency Orders 
submitted for AIM Auction processing with less than 50 standard 
option contracts (or 500 mini-option contracts) and NBBO width of 
$0.01, pursuant to Rule 21.19(b)(1)(A), which remains unchanged.
    \11\ See supra note 10.
---------------------------------------------------------------------------

    The Exchange notes that the AIM and C-AIM Auctions generally 
deliver meaningful opportunities for price improvement to orders and 
provide an efficient manner of access to liquidity for customers. The 
Exchange believes that the proposed changes to these auctions will 
permit more Agency Orders to receive such meaningful opportunities, as 
intended, and ensure they are not inadvertently penalized by being 
rejected rather than auctioned if markets move during the order 
submission process, which ultimately benefits investors.

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

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act. The Exchange does not 
believe the proposed rule change will impose any burden on intramarket 
competition because it will apply uniformly to all Agency Orders 
submitted into AIM and C-AIM Auctions and to all Members. Additionally, 
the Exchange notes that participation in the AIM and C-AIM auctions is 
completely voluntary. The Exchange believes all market participants may 
benefit from any additional liquidity, execution opportunities, and 
price improvement in the AIM and C-AIM Auctions that may result from 
the proposed rule change.
    The Exchange does not believe the proposed rule change will impose 
any burden on intermarket competition that is not necessary or 
appropriate in furtherance of the purposes of the Act, as the proposed 
rule change relates to price requirements for an Exchange-specific 
auction mechanism and will continue to require auctions to start at

[[Page 41703]]

prices at or better than the NBBO at the start of the auction.\12\
---------------------------------------------------------------------------

    \12\ See supra note 10.
---------------------------------------------------------------------------

    Finally, the Exchange notes that it operates in a highly 
competitive market, and members have numerous alternative venues they 
may participate on and direct their order flow, including other options 
exchanges that have implemented similar electronic price improvement 
mechanisms with auto-match pricing. Participants can readily choose to 
send their orders to other exchanges if they deem those other venues to 
be more favorable.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    The Exchange neither solicited nor received comments on the 
proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    Because the foregoing proposed rule change does not:
    A. significantly affect the protection of investors or the public 
interest;
    B. impose any significant burden on competition; and
    C. become operative for 30 days from the date on which it was 
filed, or such shorter time as the Commission may designate, it has 
become effective pursuant to Section 19(b)(3)(A) of the Act \13\ and 
Rule 19b-4(f)(6) \14\ thereunder. At any time within 60 days of the 
filing of the proposed rule change, the Commission summarily may 
temporarily suspend such rule change if it appears to the Commission 
that such action is necessary or appropriate in the public interest, 
for the protection of investors, or otherwise in furtherance of the 
purposes of the Act. If the Commission takes such action, the 
Commission will institute proceedings to determine whether the proposed 
rule change should be approved or disapproved.
