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 (<a href="http://markets.cboe.com/us/options/regulation/rule_filings/edgx/">http://markets.cboe.com/us/options/regulation/rule_filings/edgx/</a>), 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.
---------------------------------------------------------------------------
\18\ 15 U.S.C. 78f(b).
\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.
