5Rule 5.6(c) defines a ‘‘Book Only’’ order as an 

order the System ranks and executes pursuant to 

Rule 5.32, subjects to the Price Adjust process 

pursuant to Rule 5.32, or cancels, as applicable (in 

accordance with User instructions), without routing 

away to another exchange. Users may designate 

bulk messages as Book Only as set forth in Rule 

5.5(c). 

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. A 

User may submit a bulk message through a bulk 

port as set forth in Rule 5.5(c)(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 1.1. 

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 

5.5(c)(3). 

8To accommodate this change, the proposed rule 

change numbers the current introductory paragraph 

to Rule 5.32(b) as subparagraph (1) (some of which 

becomes subparagraph (A)) and makes 

nonsubstantive changes to reflect two 

subparagraphs to new subparagraph (1). 

9The Exchange notes that pursuant to Rule 

5.5(c)(3)(A), only appointed Market-Makers may 

submit such orders and bulk messages through a 

bulk port. 

10This is how these orders and messages are 

currently handled pursuant to Rule 5.32(b).

Self-Regulatory Organizations; Cboe 

C2 Exchange, Inc.; Notice of Filing 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 C2 Exchange, Inc. 

(‘‘Exchange’’ or ‘‘C2’’) 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 C2 Exchange, Inc. (the 

‘‘Exchange’’ or ‘‘C2 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 

website (http://markets.cboe.com/us/ 

options/regulation/rule_filings/ctwo/), 

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 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 5.32(b) 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 ranks 

and displays a buy (sell) order that at 

the time of entry would lock or cross a 

Protected Quotation of the Exchange or 

another exchange at one minimum price 

increment below (above) the current 

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

best bid (‘‘NBB’’)) (‘‘Price Adjust’’). 

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 (1)(B) to Rule 5.32(b),8

which states if the bid (offer) of a Book 

Only order or bulk message 9 submitted 

through a bulk port at the time of entry 

would lock or cross (1) a protected offer 

(bid) of another options exchange 10 or 

a resting offer (bid) with a Capacity of

Federal Register / Vol. 86, No. 152 / Wednesday, August 11, 2021 / Notices 44085 

11This is how these orders and messages are 

currently handled pursuant to Rule 5.32(b). 

12Rule 5.6(c) defines a Cancel Back order as an 

order (including a bulk message) 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. 

13The proposed rule change also clarifies in Rule 

5.32(c)(6) 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 NBBO 

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 proposed 

rule change also renumbers current subparagraph 

(3) to be subparagraph (4). 

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. 

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).11 This will permit appointed 

Market-Maker 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 Rule 

5.32(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 

5.32(c)(6) to indicate that provision will 

only apply to Cancel Back 12 Book Only 

orders and bulk messages 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 M-Capacity 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 proposed Rule 5.32(b)(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, current Rule 5.32(b)(1) 

(which the proposed rule change 

renumbers as subparagraph (2) provides 

that if the NBBO changes so that an 

order subject to Price Adjust would not 

lock or cross a Protection Quotation,14

the System gives the Price Adjust order 

a new timestamp. Currently, the rule 

states the System displays the order at 

a price that at the price that locked the 

Protected Quotation at the time of entry. 

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 current subparagraph (2) and 

moves the concept of single or multiple 

price adjust to proposed 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 

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 (b). 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 

enhances the bulk message fat finger 

check set forth in Rule 5.34(a)(5). 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-byVerDate Sep<11>2014 23:05 Aug 10, 2021 Jkt 253001 PO 00000 Frm 00098 Fmt 4703 Sfmt 4703 E:\FR\FM\11AUN1.SGM 11AUN1

class 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. 

IV. Solicitation of Comments 

Interested persons are invited to 

submit written data, views, and 

arguments concerning the foregoing, 

including whether the proposed rule 

change is consistent with the Act.

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
