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 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 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.
---------------------------------------------------------------------------

    \5\ Rule 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).
    \6\ The 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.
    \7\ A ``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).
---------------------------------------------------------------------------

    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

[[Page 44088]]

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 Market-Maker 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 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.
---------------------------------------------------------------------------

    \8\ The 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.
    \9\ This is how these orders and messages are currently handled 
pursuant to Rule 21.1(i)(1)(A)(i).
    \10\ This is how these orders and messages are currently handled 
pursuant to Rule 21.1(i)(1)(A)(ii).
---------------------------------------------------------------------------

    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 M-Capacity interest, this provision will now 
only apply to Cancel Back Book Only bulk messages and orders submitted 
through bulk ports.\13\
---------------------------------------------------------------------------

    \11\ Rule 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.
    \12\ The 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.
    \13\ The 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.
---------------------------------------------------------------------------

    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.
---------------------------------------------------------------------------

    \14\ The 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.
    \15\ The 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).
---------------------------------------------------------------------------

    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

[[Page 44089]]

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-by-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.
---------------------------------------------------------------------------

    \16\ This check does not apply to bulk messages submitted prior 
to the conclusion of the opening process or when no NBBO is 
available.
    \17\ The 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.
---------------------------------------------------------------------------

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.
---------------------------------------------------------------------------

    \19\ 15 U.S.C. 78f(b)(5).
    \20\ Id.
---------------------------------------------------------------------------

    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\
---------------------------------------------------------------------------

    \21\ See, e.g., Rule 21.17(a)(1) (market order NBBO width 
protection).
---------------------------------------------------------------------------

    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

[[Page 44090]]

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.
