5Rule 21.1(d)(7) defines ‘‘Book Only Orders’’ as 

orders that are to be ranked and executed on the 

Exchange pursuant to Rule 21.8 or cancelled, as 

appropriate, without routing away to another 

options exchange. A Book Only Order will be 

subject to the Price Adjust process set forth in Rule 

21.1(i) unless a User has entered instructions not to 

use such process. Users may designate bulk 

messages as Book Only as set forth in Rule 21.1(j). 

6The term ‘‘bulk message’’ means a bid or offer 

included in a single electronic message a User 

submits with an M Capacity to the Exchange in 

which the User may enter, modify, or cancel up to 

an Exchange-specified number of bids and offers 

(which number the Exchange announces via 

Exchange notice or publicly available technical 

specifications). A User may submit a bulk message 

through a bulk port as set forth in Rule 21.1(j)(3). 

The System handles a bulk message in the same 

manner as it handles an order or quote, unless the 

Rules specify otherwise. See Rule 16.1. 

7A ‘‘bulk port’’ is a dedicated logical port that 

provides Users with the ability to submit bulk 

messages, single orders, and auction responses, 

each subject to certain restrictions. See Rule 

21.1(j)(3).

and Immediate Effectiveness of a 

Proposed Rule Change To Enhance 

and Clarify Its Price Adjust Process 

and Modify the Bulk Message Fat 

Finger Check 

August 5, 2021. 

Pursuant to Section 19(b)(1) of the 

Securities Exchange Act of 1934 

(‘‘Act’’),1 and Rule 19b–4 thereunder,2

notice is hereby given that on July 28, 

2021, Cboe EDGX Exchange, Inc. 

(‘‘Exchange’’ or ‘‘EDGX’’) filed with the 

Securities and Exchange Commission 

(‘‘Commission’’) the proposed rule 

change as described in Items I, II, and 

III below, which Items have been 

prepared by the Exchange. The 

Exchange filed the proposal as a ‘‘noncontroversial’’ proposed rule change 

pursuant to Section 19(b)(3)(A)(iii) of 

the Act 3 and Rule 19b–4(f)(6) 

thereunder.4 The Commission is 

publishing this notice to solicit 

comments on the proposed rule change 

from interested persons. 

I. Self-Regulatory Organization’s 

Statement of the Terms of Substance of 

the Proposed Rule Change 

Cboe EDGX Exchange, Inc. (the 

‘‘Exchange’’ or ‘‘EDGX Options’’) 

proposes to enhance and clarify its Price 

Adjust process and modify the bulk 

message fat finger check. 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

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 enhance its 

Price Adjust (as defined below) process 

for certain Market-Maker interest— 

specifically Book Only 5 orders and bulk 

messages 6 submitted through bulk 

ports 7—and clarify other parts of that 

process, as well as modify the bulk 

message fat finger check. 

Rule 21.1(i) describes the Price Adjust 

process, which applies to an order 

unless a user enters instructions for the 

order to not be subject to the Price 

Adjust process. The System adjusts the 

price (‘‘Price Adjust’’) of an order 

subject to the Price Adjust as follows: 

(A) If a buy (sell) non-all-or-none 

(‘‘AON’’) order at the time of entry, 

would lock or cross: 

(i) A Protected Quotation of another 

options exchange or the Exchange, the 

System ranks and displays the order at one 

minimum price variation below (above) the 

current national best offer (‘‘NBO’’) (national 

best bid (‘‘NBB’’); or 

(ii) the offer (bid) of a sell (buy) AON order 

resting on the Book at or better than the 

Exchange’s best offer (bid), the System ranks 

the resting AON order one minimum price 

variation above (below) the bid (offer) of the 

non-AON order. 

(B) If a buy (sell) AON order, at the 

time of entry, would: 

(i) Cross a Protected Offer (Bid) of another 

options exchange or a sell (buy) AON order 

resting on the Book at or better than the 

Exchange’s best offer (bid), the System ranks 

the incoming AON order at a price equal to

44088 Federal Register / Vol. 86, No. 152 / Wednesday, August 11, 2021 / Notices 

8The Exchange notes that pursuant to Rule 

21.1(j)(3)(A), only appointed Market-Makers may 

submit such orders and bulk messages through a 

bulk port. 

9This is how these orders and messages are 

currently handled pursuant to Rule 21.1(i)(1)(A)(i). 

10This is how these orders and messages are 

currently handled pursuant to Rule 21.1(i)(1)(A)(ii). 

11Rule 21.1(l) defines a Cancel Back order as an 

order a user designates to not be subject to the Price 

Adjust process that the System cancels or rejects if 

displaying the order on the book would create a 

violation of the linkage rules or if the order cannot 

otherwise be executed or displayed in the book at 

its limit price. The System executes a Book Only— 

Cancel Back order against resting orders, and 

cancels or rejects a Post Only—Cancel Back order, 

that locks or crosses the opposite side of the BBO. 

12The proposed rule change clarifies that Rule 

21.1(j)(3)(B)(ii) applies to bulk messages as well as 

orders. This is consistent with current functionality 

and the definition of bulk message in Rule 16.1, 

which states that the System handles a bulk 

message in the same manner as it handles an order 

or quote unless the Rules specify otherwise. 

13The proposed rule change also clarifies in Rule 

21.1(j)(3)(B)(ii) that it applies if the incoming order 

or bulk message would execute against or lock 

resting M-Capacity interest. It is possible a Cancel 

Back Book Only order or bulk message may 

otherwise not execute against resting M-Capacity 

interest but would instead lock that interest if it 

rested in the book, so the System would reject that 

order or bulk message to prevent the dissemination 

of a locked market. 

14The Exchange notes that a change in the BBO 

would include a change in M-Capacity interest 

resting at the top of the Book that caused a Book 

Only bulk message or order to have its price 

adjusted. 

15The proposed rule change also moves the latter 

part of current subparagraph (2) regarding the 

priority of re-ranked and re-displayed Price Adjust 

orders to proposed subparagraph (3). 

the Protected Offer (Bid) or the offer (bid) of 

the resting AON order, respectively; or 

(ii) lock or cross a Protected Offer (Bid) of 

the Exchange, the System ranks the incoming 

AON order at a price one minimum price 

variation below (above) the Protected Offer 

(Bid). 

This Price Adjust process applies to 

Book Only orders and bulk messages 

submitted that are designated as Price 

Adjust (and not designated as Cancel 

Back). Separately, a Book Only order or 

bulk message bid or offer (or unexecuted 

portion) is rejected if submitted by a 

Market-Maker with an appointment in 

the class through a bulk port if it would 

execute against a resting offer or bid, 

respectively with a capacity of M. 

Therefore, if a Book Only bulk message 

bid of an appointed Market-Maker does 

not execute upon entry and would rest 

at the same price as an offer not 

represented by a capacity of M, that bid 

price would be adjusted and rest on the 

book at one minimum price variation 

below the offer. However, if the offer 

was represented by a capacity of M, the 

System would reject the bid since it may 

not execute against that resting offer. 

The proposed rule change amends the 

Price Adjust process so that an 

appointed Market-Maker’s Book Only 

bids and offers submitted through a bulk 

port may have the opportunity to rest on 

the book if they are submitted at the 

same price as the opposite side of the 

market when represented by MarketMaker interest. Specifically, the 

proposed rule change adds 

subparagraph (C) to Rule 21.1(i)(1), 

which states if the bid (offer) of a Book 

Only buy (sell) non-AON order or bulk 

message 8 submitted through a bulk port 

at the time of entry would lock or cross 

(1) a protected offer (bid) of another 

options exchange 9 or a resting offer 

(bid) with a Capacity of M, the System 

ranks and displays the order at one 

minimum price variation below (above) 

the better of the current away best offer 

(‘‘ABO’’) (away best bid (‘‘ABB’’)) or 

resting M-Capacity offer (bid); or (2) the 

offer (bid) of a sell (buy) AON order 

resting on the Book at or better than the 

Exchange’s best offer (bid), the System 

ranks the resting AON order one 

minimum price variation above (below) 

the bid (offer) of the non-AON order.10

This will permit appointed MarketMaker orders and quotes submitted 

through bulk ports (the primary purpose 

of which is to provide liquidity to the 

Book) that are subject to the Price 

Adjust process (indicating the 

submitting Market-Makers prefer a price 

adjustment to rejection) so their quotes 

may rest in the Book if they would 

otherwise lock interest against which 

they could not execute. 

The proposed rule change makes 

nonsubstantive changes to current Rules 

21.1(i)(1)(A) and (B) to set forth to 

which orders and bulk messages the 

functionality in each subparagraph will 

apply; the proposed rule change has no 

impact on how the Price Adjust process 

applies to orders and bulk messages 

other than Book Only orders and bulk 

messages submitted through a bulk port 

that would otherwise execute against 

resting 

M-Capacity interest. Similarly, the 

proposed rule change updates Rule 

21.1(j)(3)(B)(ii) to indicate that provision 

will only apply to Cancel Back 11 Book 

Only orders and bulk messages 12

submitted through bulk ports. Book 

Only orders and bulk messages 

submitted through a bulk port may 

either be Price Adjust or Cancel Back. 

As Price Adjust Book Only orders and 

bulk messages submitted through a bulk 

port will be handled as described above 

if they would execute against resting MCapacity interest, this provision will 

now only apply to Cancel Back Book 

Only bulk messages and orders 

submitted through bulk ports.13

The proposed rule change also 

clarifies in Rule 21.1(i)(1) that the Price 

Adjust process applies to an order or 

remaining portion that does not execute 

upon entry. This is consistent with 

current functionality, as Price Adjust 

orders may execute upon entry against 

resting interest—the price adjustment 

applies only to permit any remaining 

interest from an incoming order to rest 

at a price that would not lock or cross 

opposite side interest in accordance 

with the linkage plan. 

Additionally, Rule 21.1(i)(2) provides 

that in the event the circumstances that 

caused the System to adjust the price of 

an order pursuant to subparagraph (i)(1) 

change so that it would not lock or 

cross, as applicable, a Protection 

Quotation or an AON resting on the 

EDGX Options Book at a price at or 

better than the Exchange’s BBO,14 the 

System gives the Price Adjust order a 

new timestamp. Currently, the rule 

states the System ranks or displays the 

order at a price that locks or is one 

minimum price variation away from the 

new Protection Quotation or AON 

resting on the Book at or better than the 

BBO, as applicable. Pursuant to current 

subparagraph (3), the ranked and 

displayed price of an order subject to 

Price Adjust may be adjusted once or 

multiple times depending upon the 

instructions of a User and changes to the 

prevailing NBBO. The proposed rule 

change deletes this subparagraph (3) 

and moves the concept of single or 

multiple price adjust to subparagraph 

(2).15 The proposed rule change clarifies 

how each of single price adjust and 

multiple price adjust currently function. 

Specifically, if a User designated an 

order as eligible for single price adjust, 

the System ranks and displays the order 

at the price of the Protected Quotation 

that was present in the Book at the time 

of order entry. That is the price at which 

the Price Adjust order would have 

entered the Book but for the presence of 

that Protected Quotation. 

Additionally, the proposed rule 

change clarifies that bulk message bids 

and offers are only subject to single 

price adjust. The Exchange understands 

that Market-Makers’ automated quote 

streaming systems review their resting 

interest when the markets change and 

update as appropriate in accordance 

with their business and risk models. 

Therefore, the Exchange does not 

believe it is necessary for it also to 

review resting Market-Maker interest 

continuously and reprice as the market 

changes. The proposed rule change 

amends proposed subparagraph (2)(B) to 

indicate it applies to orders designated 

as multiple price adjust, and specifies 

the repricing described in that 


jbell on DSKJLSW7X2PROD with NOTICES
Federal Register / Vol. 86, No. 152 / Wednesday, August 11, 2021 / Notices 44089 

16This check does not apply to bulk messages 

submitted prior to the conclusion of the opening 

process or when no NBBO is available. 

17The proposed rule change also makes a 

nonsubstantive change to say the System cancels or 

rejects any bulk message bid (offer) more than a 

buffer amount above (below) the NBO (NBB) to 

align the language with other rules.

21See, e.g., Rule 21.17(a)(1) (market order NBBO 

width protection). 

paragraph may occur multiple times as 

the opposite side of the NBBO changes 

(up to the order’s limit price). The 

proposed rule change has no impact on 

how the System handles order and bulk 

messages subject to single or multiple 

price adjust; it rather more accurately 

describes this process. The proposed 

rule change also amends this provision 

to reflect that a Price Adjust bulk 

message may be re-priced upon entry 

due to the presence of opposite side M 

Capacity interest (rather than rejected in 

accordance with current functionality). 

With respect to multiple price adjust 

functionality, the proposed rule change 

clarifies that the price at which the 

System reprices an order is the ranked 

and displayed price (rather than or), 

which is consistent with the remainder 

of paragraph (i). Price Adjust orders are 

always ranked and displayed at the 

same price. Additionally, the proposed 

rule change deletes the concept of the 

new price locking a new Protected 

Quotation, as the new price will always 

be one minimum price variation away to 

be consistent with linkage rules. Finally, 

the proposed rule change deletes the 

concept of repricing a Price Adjust order 

based on the presence of an AON order. 

As set forth in Rule 21.1(i)(1), if an 

incoming order would lock the price of 

an AON resting on the book, the System 

reprices the AON rather than the 

incoming order. Therefore, if the AON 

is no longer in the book, there would be 

no reason to reprice the other order, 

making the reference to AON in 

subparagraph (2) regarding repricing is 

unnecessary. 

Finally, the proposed rule change 

enhances the bulk message fat finger 

check set forth in Rule 21.17(a)(6). In 

accordance with the fat finger check, the 

System cancels or rejects any bulk 

message bid (offer) above (below) the 

NBO (NBB) by more than a specified 

amount determined by the Exchange.16

The proposed rule change indicates that 

the Exchange may also determine a 

minimum and maximum dollar value 

for the bulk message fat finger check.17

The Exchange believes Market-Makers 

may be willing to accept an execution 

at a price beyond the NBBO at the time 

of order entry, but not too far away. The 

purpose of the fat finger check is 

intended to reject bulk message bids and 

offers that on their face are likely to be 

entered at erroneous prices and thus 

prevent potentially erroneous 

executions. The proposed rule change to 

permit the Exchange to set a minimum 

and maximum value will provide the 

Exchange with the opportunity to set a 

meaningful buffer that is not ‘‘too close’’ 

to the NBBO (in other words, a de 

minimis buffer) but not ‘‘too far’’ from 

the NBBO (in other words, a buffer that 

is more likely to accept erroneously 

priced bulk messages). The proposed 

rule change also permits the Exchange 

to set the relevant amounts for the bulk 

message fat finger check on a class-byclass basis. Option classes have different 

characteristics and trading models, and 

the proposed flexibility will permit the 

Exchange to apply different parameters 

to address those differences. 

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.18 Specifically, 

the Exchange believes the proposed rule 

change is consistent with the Section 

6(b)(5) 19 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) 20 requirement that 

the rules of an exchange not be designed 

to permit unfair discrimination between 

customers, issuers, brokers, or dealers. 

In particular, the proposed rule 

change to enhance the Price Adjust 

process to adjust the price of Book Only 

orders and bulk messages submitted by 

Market-Makers through bulk ports will 

remove impediments to and perfect the 

mechanism of a free and open market. 

Market-Makers that have elected to have 

their bulk port interest subject to the 

Price Adjust process have indicated 

their desire to have the prices of that 

interest adjusted rather than have the 

System reject that interest. The 

proposed rule change is consistent with 

that election and will cause such 

interest to be repriced rather than 

rejected in a situation—when it would 

otherwise execute or lock against other 

M-Capacity interest—in addition to 

locking an away market. Therefore, the 

proposed rule change will permit 

additional Market-Maker interest to 

enter the book rather than be rejected. 

This additional liquidity may increase 

execution opportunities and tighten 

spreads, which ultimately benefits all 

investors. 

The Exchange also believes the 

proposed rule change to codify that bulk 

message bids and offers may only be 

subject to single price adjust will benefit 

investors by adding transparency to the 

Rules. The Exchange understands that 

Market-Makers’ automated quote 

streaming systems review their resting 

interest when the markets change and 

update as appropriate in accordance 

with their business and risk models. 

Therefore, the Exchange does not 

believe it is necessary for it also to 

review resting Market-Maker interest 

continuously and reprice as the market 

changes. 

In addition, the Exchange believes the 

proposed change to the bulk message fat 

finger check will protect investors and 

the public interest as the check will 

continue to mitigate potential risks 

associated with Market-Makers 

submitting bulk message bids and offers 

at unintended prices, and risks 

associated with orders and quotes 

trading at prices that are extreme and 

potentially erroneous, which may likely 

have resulted from human or 

operational error. The proposed 

enhancement that the Exchange will 

apply a minimum and maximum to the 

fat finger check will permit the 

Exchange to apply the fat finger check 

to bulk messages in a more meaningful 

way. The Exchange believes class 

flexibility is appropriate to permit the 

Exchange to apply reasonable buffers to 

classes, which may exhibit different 

trading characteristics and have 

different market models. The Exchange 

has other price checks and risk controls 

that permit it to set a minimum and 

maximum, as well as apply parameters 

on a class basis.21

The proposed nonsubstantive and 

clarifying changes will protect investors 

by adding transparency to the Rules. 

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, as the 

proposed changes will apply in the 

same manner to all Book Only orders 

and bulk messages submitted through a 

bulk port. The proposed rule change to 

codify that bulk messages will only be 

subject to single price adjust is 

appropriate given that Market-Makers’ 

automated quote streaming systems 

review their resting interest when the 

markets change and update as 

appropriate in accordance with their 

business and risk models. Therefore, the 

Exchange does not believe it is 

necessary for it also to review resting 

Market-Maker interest continuously and 

reprice as the market changes. The 

Exchange does not believe the proposed 

rule change will impose any burden on 

intermarket competition, as the 

proposed rule change applies to 

functionality that applies to incoming 

interest that may only rest or execute on 

the Exchange’s book. 

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 22 and Rule 19b–4(f)(6) 23

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.
