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 parts 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 the description of the Super 
Aggressive instruction under paragraph (n)(2) of Exchange Rule 11.6, 
Routing/Posting Instructions to: (i) Specify that an incoming order 
with a Post Only instruction that locks a resting order with a Super 
Aggressive instruction must include a Displayed instruction for the 
order with a Super Aggressive instruction to engage in a liquidity swap 
and execute against that incoming order; and (ii) modify language from 
the description of the Super Aggressive instruction that states if an 
order that does not contain a Super Aggressive instruction maintains 
higher priority than one or more Super Aggressive eligible orders, the 
Super Aggressive eligible order(s) with lower priority will not be 
converted and the incoming order with a Post Only instruction will be 
posted or cancelled in accordance with Exchange Rule 11.6(n)(4).\5\
---------------------------------------------------------------------------

    \5\ The Exchange also proposes to remove the extraneous word 
``solely'' from the second sentence of Rule 11.6(n)(2). The removal 
of this word does not alter the operation of the Super Aggressive 
order instruction.
---------------------------------------------------------------------------

    Super Aggressive is an optional order instruction that directs the 
System \6\ to route an order when an away Trading Center locks or 
crosses the limit price of the order resting on the EDGX Book.\7\ When 
an order with a Super Aggressive instruction is locked by an incoming 
order with a Post Only instruction that does not remove liquidity 
pursuant to Rule 11.6(n)(4),\8\ the order with a Super Aggressive 
instruction is converted to an executable order and will remove 
liquidity against such incoming order.
---------------------------------------------------------------------------

    \6\ The term ``System'' is defined as ``the electronic 
communications and trading facility designated by the Board through 
which securities orders of Users are consolidated for ranking, 
execution and, when applicable, routing away.'' See Exchange Rule 
1.5(cc).
    \7\ See Exchange Rule 1.5(d).
    \8\ The Exchange will execute an order with a Post Only 
instruction priced at or above $1.00 in certain circumstances where 
the value of such execution when removing liquidity equals or 
exceeds the value of such execution if the order instead posted to 
the EDGX Book and subsequently provided liquidity, including the 
applicable fees charged or rebates provided. See Exchange Rule 
11.6(n)(4).
---------------------------------------------------------------------------

    First, the Exchange proposes to modify the behavior of the Super 
Aggressive instruction to require that the incoming order with a Post 
Only instruction that locks a resting order with a Super Aggressive 
instruction must include a Displayed instruction for an execution to 
occur. The Super Aggressive instruction is generally utilized for best 
execution purposes because it enables the order to immediately attempt 
to access displayed liquidity on another Trading Center that is either 
priced equal to or better than the order with a Super Aggressive 
instruction's limit price. The Super Aggressive instruction also 
enables the order to execute against an equally priced incoming order 
with a Post Only instruction that would otherwise not execute by being 
willing to act as the liquidity remover in such a scenario. Today, the 
incoming order with a Post Only instruction may include either a 
Displayed or Non-Displayed instruction for it to engage in a liquidity 
swap with an order with a Super Aggressive instruction resting on the 
EDGX Book.
    Consistent with the Super Aggressive instruction to access 
liquidity displayed on other Trading Centers, the Exchange proposes to 
amend the Super Aggressive instruction such that an order with such 
instruction will execute against an equally priced incoming order with 
a Post Only instruction only when such order is to be displayed on the 
EDGX Book. The order with a Super Aggressive instruction would continue 
to act as a liquidity remover in such a scenario. Should such an 
equally priced incoming order with a Post Only instruction not include 
a Displayed instruction, the resting order with a Super Aggressive 
instruction would remain on the EDGX Book and await an execution where 
it may act as a liquidity provider. The incoming order with a Post Only 
instruction and a Non-Displayed instruction would be posted to the EDGX 
Book at its limit price, creating an internally locked non-displayed 
book. As is the case today, an execution would continue to occur where 
an incoming order with a Post Only instruction is priced more 
aggressively than the order with a Super Aggressive instruction resting 
on the EDGX Book, regardless of whether the incoming order included a 
Displayed or Non-Displayed instruction.\9\
---------------------------------------------------------------------------

    \9\ See id.
---------------------------------------------------------------------------

    The Exchange notes that Users seeking to act as a liquidity remover 
once resting on the EDGX Book in all cases (i.e., seeking to execute 
against incoming Post Only orders regardless of the display 
instruction) may attach the Non-Displayed Swap (``NDS'') instruction to 
their order.\10\ The NDS instruction is similar to the Super Aggressive 
instruction, in that it also is an optional order instruction that a 
User may include on an order that directs the Exchange to have such 
order, when resting on the EDGX Book, execute against an incoming order 
with a Post Only instruction rather than have it be locked by the 
incoming order. Today, because orders with either instruction (i.e., 
Super Aggressive and NDS) will execute against incoming orders with a 
Post Only instruction regardless of whether the order is to be 
displayed, the instructions are currently identical with two 
exceptions. First, an order with a Super Aggressive instruction will 
not convert into a liquidity removing order and execute against an 
order with a Post Only instruction if there is an order on the order 
book with priority over such order that does not also contain a Super 
Aggressive instruction. As further described below, the Exchange is 
proposing to modify this feature of the Super Aggressive instruction. 
The second current distinction between the two instructions, which 
would remain, is that an order with a Super Aggressive instruction can 
be displayed on the Exchange whereas an order with the NDS instruction 
must be non-displayed. As amended, the additional distinction between 
the two instructions would be whether an order would become a liquidity 
removing order against any order with a Post Only instruction that 
would lock it (i.e., NDS) or only when the order with a Post Only 
instruction that would lock it also contains a Displayed instruction 
(i.e., Super Aggressive).
---------------------------------------------------------------------------

    \10\ See Exchange Rule 11.6(n)(7).
---------------------------------------------------------------------------

    The below examples illustrate the proposed behavior. Assume the 
National Best Bid and Offer (``NBBO'') is $10.00 by $10.10. An order to 
buy is displayed on the EDGX Book at $10.00 with a Super Aggressive 
instruction. There are no other orders resting on the EDGX Book. An 
order to sell at $10.00 with a Post Only and Displayed instruction is 
entered. The incoming order to sell would execute against the resting 
order to buy at $10.00, the

[[Page 35298]]

locking price, because the incoming order included a Displayed 
instruction. The order to buy would act as the liquidity remover and 
the order to sell would act as the liquidity adder. However, no 
execution would occur if the incoming order to sell included a Non-
Displayed instruction. Instead, the incoming order to sell would be 
posted non-displayed to the EDGX Book at $10.00, its limit price, 
causing the EDGX Book to be internally locked.
    Second, the Exchange proposes to enable an incoming order with a 
Post Only instruction and Displayed instruction to execute against an 
equally priced non-displayed order with a Super Aggressive instruction 
where a non-displayed order without a Super Aggressive instruction 
maintains time priority over the Super Aggressive eligible order at 
that price. In such case, the non-displayed, non-Super Aggressive order 
seeks to remain a liquidity provider and would cede time priority to 
the order with a Super Aggressive instruction, which is willing to act 
as a liquidity remover to facilitate the execution. The Exchange 
proposes to effect this change by modifying language in the description 
of the Super Aggressive instruction to state that if an order displayed 
on the EDGX Book does not contain a Super Aggressive instruction and 
maintains higher priority than one or more Super Aggressive eligible 
orders, the Super Aggressive eligible order(s) with lower priority will 
not be converted and the incoming order with a Post Only instruction 
will be posted or cancelled in accordance with Exchange Rule 
11.6(n)(4). Thus, an order with a Super Aggressive instruction, whether 
displayed on the Exchange or non-displayed, will never execute ahead of 
a displayed order that maintains time priority.
    The Super Aggressive instruction is designed to facilitate 
executions that would otherwise not occur due to the Post Only 
instruction requirement to not remove liquidity. Users entering orders 
with the Super Aggressive instruction tend to be fee agnostic because 
an order with a Super Aggressive instruction is willing to route to an 
away Trading Center displaying an equally or better priced order (i.e., 
pay a fee at such Trading Center). Meanwhile, an order without the 
Super Aggressive instruction elects to remain on the EDGX Book as the 
liquidity provider until it may execute against an incoming order that 
would act as the liquidity remover. Therefore, enabling the Super 
Aggressive order to execute against an incoming order, regardless of 
whether a non-displayed order without a Super Aggressive instruction 
maintains priority, is consistent with the User's intent for both 
orders--one choses to remain the liquidity provider and forgo the 
execution while the other is willing to execute irrespective of whether 
it is the liquidity provider or remover. The Exchange notes that 
similar behavior occurs for orders utilizing the NDS instruction,\11\ 
which also seeks to engage in a liquidity swap against incoming orders 
with a Post Only instruction. The Exchange, however, has proposed to 
retain the existing limitation with respect to orders displayed on the 
EDGX Book.
---------------------------------------------------------------------------

    \11\ See Exchange Rule 11.6(n)(7). See also Securities Exchange 
Act Release No. 80841 (June 1, 2017), 82 FR 26559 (June 7, 2017) 
(SR-BatsEDGX-2017-25) (including an example where an order cedes 
execution priority to an order with an NDS instruction).
---------------------------------------------------------------------------

    The following example illustrates the operation of an order with a 
Super Aggressive instruction under the proposed rule change. Assume the 
NBBO is $10.00 by $10.04. There is a non-displayed Limit Order to buy 
resting on the EDGX Book at $10.03 (``Order A''). A second non-
displayed Limit Order to buy at $10.03 is then entered with a Super 
Aggressive instruction and has time priority behind the first Limit 
Order (``Order B''). An order to sell with a Post Only instruction 
priced at $10.03 is entered. Under current behavior, the incoming sell 
order with a Post Only instruction would not execute against Order A 
and would post to the EDGX Book \12\ because the value of such 
execution against the resting buy order when removing liquidity does 
not equal or exceed the value of such execution if the order instead 
posted to the EDGX Book and subsequently provided liquidity, including 
the applicable fees charged or rebates provided. Further, the incoming 
sell order with a Post Only instruction could not execute against Order 
B because Order A is on the EDGX Book and maintains time priority over 
Order B. Under the proposed change, the incoming sell order, if it 
contained a Displayed instruction, would execute against Order B and 
Order B would become the remover of liquidity while the incoming sell 
order with a Post Only instruction would become the liquidity provider. 
In such case, Order A cedes priority to Order B because Order A did not 
also include a Super Aggressive instruction \13\ and thus the User that 
submitted the order did not indicate the preference to be treated as 
the remover of liquidity in favor of an execution; instead, by not 
using Super Aggressive, a User indicates the preference to remain 
posted on the EDGX Book as a liquidity provider. However, if the 
incoming sell order was priced at $10.02, it would receive sufficient 
price improvement to execute upon entry against all resting buy Limit 
Orders in time priority at $10.03.\14\ Also, if Order A was displayed 
on the EDGX Book, no execution would occur, as the proposed change 
would only apply to non-displayed liquidity.
---------------------------------------------------------------------------

    \12\ Such order would be posted to the EDGX Book in accordance 
with the Exchange's re-pricing instructions to comply with Rule 
610(d) of Regulation NMS. See Exchange Rule 11.6(l)(1). See also 242 
CFR 242.610(d).
    \13\ This behavior is consistent with the operation of the 
Exchange's NDS instruction. See supra note 11.
    \14\ The execution occurs here because the value of the 
execution against the buy order when removing liquidity exceeds the 
value of such execution if the order instead posted to the EDGX Book 
and subsequently provided liquidity, including the applicable fees 
charged or rebates provided. See supra note 8.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act \15\ in general, and furthers the objectives of Section 
6(b)(5) of the Act \16\ in particular, in that it is designed to 
promote just and equitable principles of trade, to foster cooperation 
and coordination with persons engaged in 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.
---------------------------------------------------------------------------

    \15\ 15 U.S.C. 78f(b).
    \16\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The proposed changes to the Super Aggressive order instruction are 
designed to promote just and equitable principles of trade, to foster 
cooperation and coordination with persons engaged in 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. The Super 
Aggressive instruction is an optional feature that is intended to 
reflect the order management practices of various market participants. 
The proposal to limit the execution of an order with a Super Aggressive 
instruction to execute against incoming orders with a Post Only 
instruction that also contain a Displayed instruction promotes just and 
equitable principles of trade because it enables Users to elect an 
order instruction consistent with their intent to execute only against 
displayed orders, in part, for best execution

[[Page 35299]]

purposes. The amended Super Aggressive instruction would ensure 
executions at the best available price displayed on another Trading 
Center or against an incoming order that would have been displayed on 
the EDGX Book. Users seeking to act as a liquidity remover once resting 
on the EDGX Book and execute against an incoming order with a Post Only 
and Non-Displayed instruction may attach the NDS instruction to their 
order.\17\
---------------------------------------------------------------------------

    \17\ See Exchange Rule 11.6(n)(7).
---------------------------------------------------------------------------

    The proposed change to the Super Aggressive instruction also 
removes impediments to and perfects the mechanism of a free and open 
market and a national market system because it is designed to 
facilitate executions that would otherwise not occur due to the Post 
Only instruction requirement to not remove liquidity. The proposal 
enables non-displayed Super Aggressive orders to execute against an 
incoming order, regardless of whether another non-displayed order 
without a Super Aggressive instruction maintains priority consistent 
with the User's intent for both orders--one chooses to remain the 
liquidity provider and forgo the execution while the other is willing 
to execute irrespective of whether it is the liquidity provider or 
remover. The non-Super Aggressive order seeks to remain a liquidity 
provider and cede its time priority to the order with a Super 
Aggressive instruction, which is willing to act as a liquidity remover 
to facilitate the execution. It also enables an order without the Super 
Aggressive instruction to remain on the EDGX Book as a liquidity 
provider, consistent with the expected operation of their resting 
order. The Exchange notes that similar behavior occurs for orders 
utilizing the NDS \18\ instruction, which also seeks to engage in a 
liquidity swap against incoming orders with a Post Only instruction. 
Finally, by limiting the proposed change to non-displayed orders, the 
proposal remains consistent with NDS and also retains existing 
functionality with respect to the handling of displayed orders.
---------------------------------------------------------------------------

    \18\ See supra note 11.
---------------------------------------------------------------------------

    For the reasons set forth above, the Exchange believes the proposal 
removes impediments to and perfects the mechanism of a free and open 
market and a national market system, and, in general, protects 
investors and the public interest.

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
result in any burden on competition that is not necessary or 
appropriate in furtherance of the purposes of the Act, as amended. On 
the contrary, the proposed changes to the Super Aggressive order 
instruction are intended to improve the usefulness of the instruction 
and to align its operation with the intention of the User, resulting in 
enhanced competition through increased usage and execution quality on 
the Exchange. Thus, to the extent the change is intended to improve 
functionality on the Exchange to encourage Users to direct their orders 
to the Exchange, the change is competitive, but the Exchange does not 
believe the proposed change will result in any burden on intermarket 
competition as it is a minor change to available functionality. The 
proposed changes to the Super Aggressive order instruction also promote 
intramarket competition because they will facilitate the execution of 
orders that would otherwise remain unexecuted consistent with the 
intent of the User entering the order, thereby increasing the efficient 
functioning of the Exchange. Further, the Super Aggressive order 
instruction will remain available to all Users in the same way it is 
today. Thus, Users can continue to choose between various optional 
order instructions, including Super Aggressive, NDS, and others, 
depending on the order handling they prefer the Exchange to utilize. 
Therefore, the Exchange does not believe the proposed rule change will 
result in any burden on intramarket competition that is not necessary 
or appropriate in furtherance of the purposes of the Act.

C. Self-Regulatory Organization's Statement on Comments on the Proposed 
Rule Change Received From Members, Participants, or Others

    The Exchange has neither solicited nor received written 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: (i) 
Significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
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)(iii) of the Act \19\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\20\
---------------------------------------------------------------------------

    \19\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \20\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change at 
least five business days prior to the date of filing of the proposed 
rule change, or such shorter time as designated by the Commission. 
The Exchange has satisfied this requirement.
---------------------------------------------------------------------------

    A proposed rule change filed under Rule 19b-4(f)(6) normally does 
not become operative for 30 days after the date of the filing. However, 
Rule 19b-4(f)(6)(iii) \21\ permits the Commission to designate a 
shorter time if such action is consistent with the protection of 
investors and the public interest. In its filing, EDGX requested that 
the Commission waive the 30-day operative delay so that the Exchange 
can implement the proposed rule change promptly after filing. The 
Exchange stated that the proposal to allow an order with a Super 
Aggressive instruction to execute against an incoming Post Only order 
only if the Post Only order is displayable is consistent with the use 
of the Super Aggressive instruction to access liquidity displayed on 
other Trading Centers. Further, according to the Exchange, users 
seeking to execute against incoming non-displayable Post Only orders 
will continue to be able to attach the NDS order instruction, as well 
as other order instructions that may permit such executions. In 
addition, the Exchange stated that the proposed priority change where 
non-displayed orders without a Super Aggressive instruction would cede 
priority to non-displayed orders with a Super Aggressive instruction is 
similar to, and consistent with, the Exchange's priority ceding 
functionality for orders with an NDS instruction and would facilitate 
executions that would otherwise not occur due to an incoming Post Only 
order's requirement not to remove liquidity. The Commission believes 
that waiver of the 30-day operative delay is consistent with the 
protection of investors and the public interest, as the proposed rule 
change relates to optional functionality that is consistent with 
existing functionality and, if selected by Exchange users, may enable 
them to better manage their orders and may increase order interaction 
on the Exchange. Accordingly, the Commission hereby waives the 30-day 
operative delay and designates the proposed rule change operative upon 
filing.\22\
---------------------------------------------------------------------------

    \21\ 17 CFR 240.19b-4(f)(6)(iii).
    \22\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if

[[Page 35300]]

it appears to the Commission that such action is: (i) Necessary or 
appropriate in the public interest; (ii) for the protection of 
investors; or (iii) otherwise in furtherance of the purposes of the 
Act. If the Commission takes such action, the Commission shall 
institute proceedings to determine whether the proposed rule should be 
approved or disapproved.
