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

    Cboe BZX Exchange, Inc. (the ``Exchange'' or ``BZX Options'') 
proposes to amend Rule 21.1 in connection with Time-in-Force 
instructions available for bulk messages and to make a clarifying 
change. 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/equities/regulation/rule_filings/bzx/), 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 Rules 21.1(f) and (l) to allow Users 
to instruct bulk messages with a Time-in-Force of Immediate or Cancel 
(``IOC''). Currently, Users may not designate bulk messages as IOC, 
which, pursuant to Rule 21.1(f)(2), instructs a limit order to be 
executed in whole or in part as soon

[[Page 57206]]

as such order is received. The portion not so executed immediately on 
the Exchange or another options exchange is cancelled and is not posted 
to the BZX Options Book. A bulk message is a bid or offer included in a 
single electronic message a User submits with an M Capacity (i.e., for 
the account of a Market Maker) to the Exchange in which the User may 
enter, modify, or cancel up to an Exchange-specified number of bids and 
offers. More, specifically, bulk message functionality is available to 
Market Makers and permits them to update their electronic quotes in 
block quantities across series in a class. Rule 21.1(l)(3)(A)(i) 
currently provides that a bulk message submitted through a dedicated 
logical port (i.e., a ``bulk port'') has a Time-in-Force of Day. 
Pursuant to Rule 21.1(f)(3), the term ``Day'' means, for an order so 
designated, a limit order to buy or sell which, if not executed expires 
at the RTH market close. All bulk messages have a Time in Force of DAY, 
as set forth in Rule 21.1(l).
    The Exchange proposes to allow Market Makers to designate bulk 
messages as IOC by amending the following: Rule 21.1(l)(3)(A)(i) to 
provide that a bulk message submitted through a bulk port has a Time-
in-Force of Day or IOC; the definition of IOC in Rule 21.1(f)(2) to 
provide that Users may designate bulk messages as IOC; and the 
definition of ``Day'' in Rule 21.1(f)(3) to remove the language that 
all bulk messages have a Time-in-Force of DAY, as set forth in Rule 
21.1(l), and instead provide that Users may designate bulk messages as 
Day.
    A Market Maker's primary purpose is to provide liquidity to the 
market, which it may do in various ways, including resting quotes on 
the Book as well as submitting quotes to trade against other resting 
interest on the Book. In addition to providing liquidity via continuous 
quotes in a Market Maker's appointed classes,\5\ as part of its quoting 
obligations, a Market Maker is also required to maintain active markets 
in its appointed classes, update quotations in response to changed 
market conditions in its appointed classes and compete with other 
Market Makers in its appointed classes.\6\ As part of a Market Maker's 
efforts to satisfy these obligations, a Market Maker may update quotes 
with the specific purpose of removing interest resting in the Book. 
This may provide additional execution opportunities for customers, 
thereby encouraging an increase in overall participation in an 
appointed class.
---------------------------------------------------------------------------

    \5\ See Rule 22.5(a)(1).
    \6\ See Rule 22.5(a)(3),(5) and (6).
---------------------------------------------------------------------------

    Currently, if a Market Maker wishes to execute against interest in 
the Book, a Market Maker will enter a Book Only bulk message or modify 
an existing bulk message to attempt to execute against such interest, 
followed immediately by a bulk message to cancel the preceding bulk 
message (or unexecuted portion) so that no portion of that bulk message 
will remain displayed on the Book. Essentially, in order to execute 
against interest on the Book, Market Makers may currently send a 
sequence of bulk messages that mimic the result of an IOC instruction--
ultimately the bulk message is cancelled and does not post to the Book 
if it is not executed immediately against resting interest. Sending a 
bulk message to cancel immediately following the submission of a bulk 
message or a bulk message modification to execute against resting 
interest creates an extra step for Market-Makers (compared to Options 
Members that may use IOC orders to accomplish this) using bulk message 
functionality and requires the System to process additional messages. 
As such, the proposed rule change to permit Market Makers to designate 
their bulk messages as IOC would allow them to attempt more effectively 
and efficiently to execute against interest in the Book and would 
reduce message traffic by eliminating the need for Market Makers to 
send multiple messages to attempt this. The Exchange notes that Market 
Makers may already use bulk messages to remove liquidity from the Book 
(if they so elect) using the ``Book Only'' instruction and, as 
described above, Market Makers may already use bulk messages to remove 
liquidity without letting nonexecuted size rest on the Book. The 
proposed rule change merely streamlines the manner in which Market 
Makers may already utilize bulk messages to execute against interest on 
the Book without sending an unexecuted bulk message (or unexecuted 
portion) to the Book thereafter. Also, Market Makers may already 
designate their quotes submitted in an order as IOC.\7\
---------------------------------------------------------------------------

    \7\ The Exchange notes that a Market-Maker may submit their 
quotes electronically in an order or bulk message. The Exchange also 
notes that, while Market-Makers may currently instruct their orders, 
including quotes submitted as orders, as IOC, the Exchange 
understands that Market-Makers predominantly conduct their trading 
activity through and design their business models around the use 
bulk messages.
---------------------------------------------------------------------------

    The Exchange notes that bulk message functionality is designed to 
facilitate Market Makers quoting on the Exchange in connection with 
their responsibility as liquidity providers. For example, the current 
requirement that bulk messages have a Time-in-Force of Day is 
consistent with general practice of Market Makers to enter new quotes 
at the beginning of each trading day, as well as a Market Maker's 
obligation to update its quotes in response to changed market 
conditions in its appointed classes. The provision that allows Market 
Makers to designate their bulk messages as Post Only or Book Only is 
intended to provide Market Makers with flexibility to use these 
instructions to permit them to execute against resting interest upon 
entry or add liquidity to the Book in connection with their various 
obligations in a manner they deem appropriate.\8\ The Exchange believes 
that the proposed rule change likewise permits Market Makers to use an 
instruction with respect to their bulk messages as an additional tool 
to provide liquidity to the market and meet their various obligations 
(such as maintaining active markets in an appointed class, updating 
quotations in response to changed market conditions in an appointed 
class and competing with other Market Makers in an appointed class) in 
a manner they deem appropriate, which may include removing interest in 
the Book to subsequently post updated quotes at potentially tighter 
spreads and to provide additional execution opportunities at 
potentially improved prices. The Exchange also believes that the 
proposed rule change enhances a current means by which Market Makers 
use bulk messages to facilitate the provision of liquidity on the 
Exchange. That is, Market Makers using bulk messages with an IOC 
instruction, as proposed, may more efficiently execute against resting 
interest, thereby increasing execution opportunities for orders resting 
on the Book. An increase in transactions on the Exchange may facilitate 
tighter spreads and price discovery, and, as a result, encourage 
increased participation and additional order flow from other market 
participants. The Exchange notes that

[[Page 57207]]

the submission of bulk messages to the Exchange is voluntary and that 
Market Makers may continue to elect to use bulk messages designated as 
Day in the same manner as they do today, including sending a bulk 
message immediately followed by a cancel to attempt to execute against 
resting interest.
---------------------------------------------------------------------------

    \8\ See Securities Exchange Release Nos. 84928 (December 21, 
2018) 83 FR 67794 (December 31, 2018) (SR-CboeBZX-2018-092); and 
88817 (May 6, 2020), 85 FR 28112 (May 12, 2020) (SR-CboeBZX-2020-
037). The Exchange notes that SR-CboeBZX-2018-092 implemented bulk 
message functionality to be consistent with the bulk message 
functionality, also adopted at that time, by its affiliated options 
exchange, Cboe Exchange, Inc. (``Cboe Options''). The Exchange notes 
that Cboe Option's bulk message functionality replaced its prior 
block quoting functionality, which likewise allowed a Market Maker 
to submit a single message containing bids and offers in multiple 
series; however, Cboe Options Rules did not prohibit an IOC 
designation for quotes submitted in block quantities.
---------------------------------------------------------------------------

    The proposed rule change also updates Rule 21.1(d), which defines 
the term ``Order Type'', and Rule 21.1(f), which defines the term 
``Time-in-Force'', to clarify the manner in which an Order Type or 
Time-in-Force, respectively, applies to a bulk message. Currently, an 
Order Type or Time-in-Force applied to a bulk message applies to each 
bid and offer within that bulk message. The proposed rule change 
updates Rules 21.1(d) and (f) to make this explicit for Order Type and 
Time-in-Force designations, respectively. The proposed rule change does 
not alter any current functionality, but instead adds clarity to the 
definition of Order Type and Time-in Force by more accurately 
reflecting the current application of such designations to bulk 
messages.
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.\9\ Specifically, the 
Exchange believes the proposed rule change is consistent with the 
Section 6(b)(5) \10\ 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) \11\ requirement that the rules of an exchange not be 
designed to permit unfair discrimination between customers, issuers, 
brokers, or dealers.

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

    In particular, the Exchange believes that the proposed rule change 
allowing Market Makers to designate their bulk messages as IOC will 
remove impediments to and perfect the mechanism of a free and open 
market and national market system and benefit investors by permitting 
Market Makers to more effectively and efficiently execute bulk messages 
against specific interest on the Book without posting an unexecuted 
bulk message (or unexecuted portion) to the Book thereafter. As 
described above, Market Makers already submit bulk messages in a manner 
that mimics an IOC instruction; the proposed rule change merely 
streamlines this process for Market Makers by allowing them to use a 
Time-in-Force instruction currently available for their orders (which 
may also contain a Market Maker's quotes) on the Exchange today. In 
addition to this, Market Makers may already include Book Only 
instructions that permit their bulk messages to remove liquidity from 
the Book. The proposed rule change is designed to benefit market 
participants by increasing efficiency and reducing additional message 
traffic by eliminating the need for Market Makers to send an additional 
bulk message to cancel along with their bulk messages in instances in 
which they wish to execute against interest that appears on the Book. 
The proposed rule change allows Market Makers to elect to use their 
bulk messages as additional tools to meet their various obligations in 
a manner they deem appropriate, consistent with the purpose of bulk 
message functionality to facilitate Market Makers' provision of 
liquidity, which may include removing interest in the Book to 
subsequently post updated quotes at potentially tighter spreads and to 
provide additional execution opportunities at potentially improved 
prices. Also, the use of IOC bulk messages for Market Makers may 
ultimately facilitate the provision of additional liquidity on the by 
increasing execution opportunities on the Exchange, as an increase in 
transactions on the Exchange may facilitate tighter spreads and price 
discovery, thereby encouraging increased participation and additional 
order flow from other market participants, to the benefit of all 
investors. Market Makers may continue to elect to use bulk messages 
designated as Day in the same manner as they do today, including 
sending a bulk message immediately followed by a cancel to attempt to 
execute against resting interest.
    Additionally, the Exchange does not believe that the proposed rule 
change would permit unfair discrimination as bulk message functionality 
is principally designed to facilitate the provision of liquidity by 
Market Makers to the Exchange and help Market Makers satisfy their 
obligations. The Exchange believes that Market Makers play a unique and 
critical role in the options market by providing liquid and active 
markets and are subject to various quoting obligations (which other 
market participants are not), including an obligation to maintain 
active markets, to update quotations in response to changed market 
conditions and to compete with other Market Makers in its appointed 
classes. Bulk message functionality, including an IOC bulk message, 
provides Market Makers with a means to help them satisfy these 
obligations. As noted above, Market Makers are already able to use Book 
Only bulk messages to execute against resting liquidity in multiple 
series across a class and to cancel quotes in multiple series across a 
class. The proposed rule change simply allows Market Makers to utilize 
their bulk messages in the same manner, just with a single message.
    Additionally, the Exchange believes that the proposed rule change 
regarding the manner in which an Order Type and Time-in-Force 
instruction is applied to bulk messages removes impediments to and 
perfects the mechanism of a free and open market and national market 
system by amending Rules 21.1(d) and (f) to reflect current 
functionality. The proposed rule change is merely a clarification in 
the Rule intended to more accurately reflect how bulk message 
functionality currently works, thereby increasing transparency in the 
Rule and ultimately benefitting investors. The proposed clarification 
does not alter any current functionality and is simply intended to 
provide clarity to the Rule.

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 that the proposed rule change in connection with IOC bulk 
messages will impose any burden on intramarket competition that is not 
necessary or appropriate in furtherance of the purposes of the Act 
because the IOC instruction for bulk messages will be available for all 
Market Makers that choose to submit bulk messages. Use of the IOC 
instruction for bulk messages is voluntary, and Market Makers may 
choose to continue to only apply the Day Time-in-Force to bulk messages 
and continue to attempt to execute bulk messages against resting 
interest using multiple messages as they

[[Page 57208]]

do today. The proposed rule change permits Market Makers to use a Time-
in-Force that is already available to all Options Members, including 
Market Makers, to apply to their orders. While only Market Makers may 
submit IOC bulk messages (as only Market Makers may currently submit 
any bulk messages), the Exchange believes this is appropriate given the 
various obligations Market Makers must satisfy under the Rules and the 
unique and critical role Market Makers play in the options market by 
providing liquid and active markets. The Exchange believes providing 
Market Makers with flexibility to use the IOC instruction with respect 
to bulk messages will provide Market Makers with an enhanced tool to 
provide liquidity to the market and satisfy their obligations in a 
manner they deem appropriate, as they are similarly able to do today by 
electing the Book Only and Post Only instructions for their bulk 
messages.
    The Exchange does not believe that the proposed rule change in 
connection with IOC bulk messages will impose any burden on intermarket 
competition that is not necessary or appropriate in furtherance of the 
purposes of the Act as it relates to quoting functionality available to 
Market Makers on the Exchange. The Exchange notes that market 
participants on other exchanges are welcome to become Market Makers on 
the Exchange if they determine that this proposed rule change has made 
participation as a Market Maker on the Exchange more attractive or 
favorable.
    The proposed rule change in connection with the application of 
Order Type and Time-in-Force instructions to bulk messages is not 
competitive in nature but is merely a clarification in the Rule, 
consistent with existing bulk message functionality and intended to 
provide clarity to the Rule by more accurately reflecting the current 
bulk message functionality. All Order Type and Time-in-Force 
instructions will continue to apply to bulk messages in the same manner 
as they do today.

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 \12\ and 
Rule 19b-4(f)(6) \13\ 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.
