Self-Regulatory Organizations; Nasdaq BX, Inc.; Notice of Filing 
and Immediate Effectiveness of Proposed Rule Change To Amend the Order 
Routing Rule in BX Chapter VI, Section 11

June 6, 2019.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on May 29, 2019, Nasdaq BX, Inc. (``BX'' or ``Exchange'') filed with 
the Securities and Exchange Commission (``SEC'' or ``Commission'') the 
proposed rule change as described in Items I and II below, which Items 
have been prepared by the Exchange. The Commission is publishing this 
notice to solicit comments on the proposed rule change from interested 
persons.

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

    The Exchange proposes to amend Chapter VI, Section 11, titled 
``Order Routing''.
    The text of the proposed rule change is available on the Exchange's 
website at http://nasdaqbx.cchwallstreet.com/, at the principal office 
of the Exchange, 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 BX Chapter VI, Section 11, titled 
``Order Routing'' to conform the rule text of BX's Chapter VI, Section 
11, where applicable, to Phlx Rule 1093 where the routing behavior is 
identical. Further the Exchange is amending BX Chapter VI, Section 11 
to add more clarity and correct the current Rule. The proposed changes 
will be discussed below in greater detail.
Universal Change
    The Exchange proposes to amend the term ``BX Options'' to simply 
state ``Exchange'' throughout this rule.
Chapter VI, Section 11(a)
    Nasdaq Phlx LLC recently amended its routing rule.\3\ As stated 
above, BX proposes to conform the rule text of BX Chapter VI, Section 
11, where applicable, to Phlx Rule 1093 where the routing behavior is 
identical. The Exchange notes that the amendments to BX Chapter VI, 
Section 11 reflect the current operation of the System. The purpose of 
the amendment is to align the rule to the specific operation of the 
routing functionality on BX.
---------------------------------------------------------------------------

    \3\ See Securities Exchange Act Release No. 85519 (April 5, 
2019), 70 FR 14686 (April 11, 2019) (SR-Phlx-2019-07).
---------------------------------------------------------------------------

    The Exchange proposes to provide rule text within paragraph (a) to 
BX Chapter VI, Section 11 \4\ similar to Phlx Rule 1093(a). While Phlx 
offers a FIND and SRCH routing strategy, BX offers a SEEK and SRCH \5\ 
routing strategy.\6\ In addition, Phlx's All-or-None \7\ Order type 
differs from BX. The BX BBO is representative of the displayed orders 
on the BX Order Book. Finally, BX defines a Public Customer at Chapter 
I, Section 1(a)(50), while Phlx defines Public Customer within Rule 
1093(a).\8\
---------------------------------------------------------------------------

    \4\ Proposed BX Chapter VI, Section 11(a) would provide, ``BX 
offers two routing strategies, SEEK and SRCH. Each of these routing 
strategies will be explained in more detail below. An order may in 
the alternative be marked Do Not Route or ``DNR''. The Exchange 
notes that for purposes of this rule the System will route SEEK and 
SRCH Orders with no other contingencies. Immediate or Cancel 
(``IOC'') Orders will be cancelled immediately if not executed, and 
will not be routed. The System checks the Order Book for available 
contracts for potential execution against the SEEK or SRCH Orders. 
After the System checks the Order Book for available contracts, 
orders are sent to other available market centers for potential 
execution. When checking the Order Book, the System will seek to 
execute at the price at which it would send the order to an away 
market. For purposes of this rule, a Route Timer shall not exceed 
one second and shall begin at the time orders are accepted into the 
System, and the System will consider whether an order can be routed 
at the conclusion of each Route Timer. Finally, for purposes of this 
rule, ``exposure'' or ``exposing'' an order shall mean a 
notification sent to participants with the price, size, and side of 
interest that is available for execution. Exposure notifications 
will be sent to participants in accordance with the routing 
procedures described in Section 11(c)(ii) below except if an 
incoming order is joining an already established BBO price when the 
ABBO is locked or crossed with the BBO, in which case such order 
will join the established BBO price and no exposure notification 
will be sent. An order exposure will be sent if the order size is 
modified. For purposes of this rule BX's opening process is governed 
by Chapter VI, Section 8 and includes an opening after a trading 
halt (``Opening Process'').''
    \5\ The SRCH routing functionalities for Phlx and BX are 
different and therefore are not being conformed.
    \6\ BX does not have a FIND routing strategy similar to Phlx.
    \7\See Phlx Rule 1078. Phlx's All-or-None Order is non-
displayed. This order type could cause Phlx's Order Book to differ 
from the displayed PBBO. BX has no such non-displayed order type.
    \8\ BX Section 1(a)(50) provides, ``The term ``Public Customer'' 
means a person that is not a broker or dealer in securities and is 
not a professional as defined within BX Rule at Chapter I, Section 
1(a)(49).''
---------------------------------------------------------------------------

    The Exchange proposes a new second paragraph at BX Chapter VI, 
Section 11(a).\9\ This paragraph does not conform to Phlx Rule 1093. 
The proposed rule

[[Page 27375]]

text currently exists within the BX rule and is being amended and 
relocated as described herein. The first sentence of current BX Chapter 
VI, Section 11(a) \10\ is being amended and relocated to proposed BX 
Chapter VI, Section 11(a). The current sentence provides, ``For System 
securities, the order routing process shall be available to 
Participants from 9:30 a.m. Eastern Time until market close and shall 
route orders as described below.'' The amendment to the rule text is 
not substantive. The Exchange proposes to relocate the remainder of 
current BX Chapter VI, Section 11(a) to the first sentence of the 
second paragraph of proposed BX Chapter VI, Section 11(a). Finally, the 
Exchange proposes to relocate current BX Chapter VI, Section 11(a)(1) 
\11\ to the second paragraph of proposed Chapter VI, Section 11(a).
---------------------------------------------------------------------------

    \9\ The second paragraph of proposed BX Chapter VI, Section 
11(a) would provide, ``Routing options may be combined with all 
available order types and times-in-force, with the exception of 
order types and times-in-force whose terms are inconsistent with the 
terms of a particular routing option. The term ``System routing 
table'' refers to the proprietary process for determining the 
specific trading venues to which the System routes orders and the 
order in which it routes them. The Exchange reserves the right to 
maintain a different System routing table for different routing 
options and to modify the System routing table at any time without 
notice. The order routing process shall be available to Participants 
from 9:30 a.m. Eastern Time until market close and shall route 
orders as described below. Participants can designate orders as 
either available for routing or not available for routing. All 
routing of orders shall comply with Chapter XII, Options Order 
Protection and Locked and Crossed Market Rules.''
    \10\ Current BX Chapter VI, Section 11(a) provides, ``For System 
securities, the order routing process shall be available to 
Participants from 9:30 a.m. Eastern Time until market close and 
shall route orders as described below. Participants can designate 
orders as either available for routing or not available for routing. 
All routing of orders shall comply with Chapter XII, Options Order 
Protection and Locked and Crossed Market Rules.''
    \11\ Current BX Chapter VI, Section 11(a)(1) provides, ``The 
system provides a number of routing options pursuant to which orders 
are sent to other available market centers for potential execution, 
per the entering firm's instructions. Routing options may be 
combined with all available order types and times-in-force, with the 
exception of order types and times-inforce whose terms are 
inconsistent with the terms of a particular routing option. The term 
``System routing table'' refers to the proprietary process for 
determining the specific trading venues to which the System routes 
orders and the order in which it routes them. The Exchange reserves 
the right to maintain a different System routing table for different 
routing options and to modify the System routing table at any time 
without notice.'' The Exchange notes that this partial sentence is 
being deleted as unnecessary ``The system routing options are:''
---------------------------------------------------------------------------

    Proposed BX Chapter VI, Section 11(a)(i) \12\ is being relocated 
from current BX Chapter VI, Section 11(c) \13\ with some minor non-
substantive changes to the rule text to conform the paragraph to Phlx 
Rule 1093(a)(i).
---------------------------------------------------------------------------

    \12\ Current BX Chapter VI, Section 11(b) is reserved and is 
being deleted.
    \13\ Current BX Chapter VI, Section 11(c) provides, ``Priority 
of Routed Orders. Orders sent by the System to other markets do not 
retain time priority with respect to other orders in the System and 
the System shall continue to execute other orders while routed 
orders are away at another market center. Once routed by the System, 
an order becomes subject to the rules and procedures of the 
destination market including, but not limited to, order 
cancellation. A routed order can be for less than the original 
incoming order's size. If a routed order is subsequently returned, 
in whole or in part, that routed order, or its remainder, shall 
receive a new time stamp reflecting the time of its return to the 
System, unless any portion of the original order remains on the 
System, in which case the routed order shall retain its timestamp 
and its priority.''
---------------------------------------------------------------------------

    Current BX Chapter VI, Section 11(d) \14\ is proposed to be 
relocated to proposed BX Chapter VI, Section 11(a)(ii) with some minor 
non-substantive changes.
---------------------------------------------------------------------------

    \14\ Current BX Chapter VI, Section 11(d) provides, ``Options 
Participants whose orders are routed to away markets shall be 
obligated to honor such trades that are executed on away markets to 
the same extent they would be obligated to honor a trade executed on 
BX Options.''
---------------------------------------------------------------------------

    The Exchange proposes to relocate BX Chapter VI, Section 11(e) \15\ 
and (f) \16\ to proposed BX Chapter VI, Section 11(a)(ii)(A)-(F). 
Current Chapter VI, Section 11(g), ``Cancellation of Orders and Error 
Account'' is being re-lettered from ``g'' to ``b'' with no changes to 
the rule text.
---------------------------------------------------------------------------

    \15\ Current BX Chapter VI, Section 11(e) provides, ``BX Options 
shall route orders in options via Nasdaq Execution Services, LLC 
(``NES''), a broker-dealer that is a member of an unaffiliated SRO 
which is the designated examining authority for the broker-dealer. 
NES serves as the Routing Facility of BX Options. The sole function 
of the Routing Facility will be to route orders in options listed 
and open for trading on BX Options to away markets either directly 
or through one or more third-party unaffiliated routing broker-
dealers pursuant to BX Options rules on behalf of BX Options. The 
Exchange and NES may not use a routing broker for which the Exchange 
or any affiliate of the Exchange is the designated examining 
authority. The Routing Facility is subject to regulation as a 
facility of BX, including the requirement to file proposed rule 
changes under Section 19 of the Act.
    Use of NES to route orders to other market centers is optional. 
Parties that do not desire to use NES must designate orders as not 
available for routing.
    The Exchange will determine the logic that provides when, how, 
and where orders are routed away to other exchanges. Except as 
provided in subparagraph (f) below, the routing broker(s) cannot 
change the terms of an order or the routing instructions, nor does 
the routing broker have any discretion about where to route an 
order.
    BX Options shall establish and maintain procedures and internal 
controls reasonably designed to adequately restrict the flow of 
confidential and proprietary information between the Exchange and 
its facilities (including the Routing Facility), and any other 
entity; or, where there is a routing broker, the Exchange, the 
Routing Facility and any routing broker, and any other entity, 
including any affiliate of the routing broker (and if the routing 
broker or any of its affiliates engages in any other business 
activities other than providing routing services to the Exchange, 
between the segment of the routing broker or affiliate that provides 
the other business activities and the segment of the routing broker 
that provides the routing services).
    The books, records, premises, officers, directors, agents, and 
employees of the Routing Facility, as a facility of the Exchange, 
shall be deemed to be the books, records, premises, officers, 
directors, agents, and employees of the Exchange for purposes of and 
subject to oversight pursuant to the Exchange Act. The books and 
records of the Routing Facility, as a facility of the Exchange, 
shall be subject at all times to inspection and copying by the 
Exchange and the Commission.''
    \16\ Current BX Chapter VI, Section 11(f) provides, ``Market 
Access. In addition to the Exchange Rules regarding routing to away 
trading centers, NES has, pursuant to Rule 15c3-5 under the Act, 
implemented certain tests designed to mitigate risks associated with 
providing the Exchange's Members with access to such away trading 
centers. Pursuant to the policies and procedures developed by NES to 
comply with Rule 15c3-5, if an order or series of orders are deemed 
to be violative of applicable pre-trade requirements under Rule 
15c3-5, the order will be rejected prior to routing and/or NES will 
seek to cancel the order if it has been routed.''
---------------------------------------------------------------------------

DNR Orders
    The Exchange proposes to add a new BX Chapter VI, Section 
11(a)(iii) \17\ with the following text, ``The following order types 
are available:''. The Exchange proposes to relocate and amend current 
BX Chapter VI, Section 11(a)(1)(C) \18\ to

[[Page 27376]]

proposed BX Chapter VI, Section 11(a)(iii) with some amendments. This 
proposed rule text is identical to Phlx Rule 1093(a)(iii)(A).
---------------------------------------------------------------------------

    \17\ Proposed BX Chapter VI, Section 11(a)(iii) provides, ``DNR 
Order. A DNR Order will never be routed outside of BX regardless of 
the prices displayed by away markets. A DNR Order may execute on the 
Exchange at a price equal to or better than, but not inferior to, 
the best away market price but, if that best away market remains, 
the DNR Order will remain in the BX Order Book and be displayed at a 
price one minimum price variation (``MPV'') inferior to that away 
best bid/offer. If the DNR Order is locking or crossing the ABBO, 
the DNR Order shall be entered into the Order Book at the ABBO price 
and displayed one MPV away from the ABBO. The Exchange shall 
immediately expose the order at the ABBO to participants, provided 
the option series has opened for trading. Any incoming order 
interacting with such a resting DNR Order will execute at the ABBO 
price, unless the ABBO is improved to a price which crosses the 
DNR's displayed price, in which case the incoming order will execute 
at the previous ABBO price. Should the best away market change its 
price to an inferior price level, the DNR Order will automatically 
re-price from its one MPV inferior to the original away best bid/
offer price to one minimum trading increment away from the new away 
best bid/offer price or its original limit price, and expose such 
orders at the ABBO to participants only if the re-priced order locks 
or crosses the ABBO. Once priced at its original limit price, it 
will remain at that price until executed or cancelled. Should the 
best away market improve its price such that it locks or crosses the 
DNR Order limit price, the Exchange will execute the resulting 
incoming order that is routed from the away market that locked or 
crossed the DNR Order limit price.
    \18\ Current BX Chapter VI, Section 11(a)(1)(C) provides, ``DNR 
Order. A DNR order will never be routed outside of the Exchange 
regardless of the prices displayed by away markets. A DNR order may 
execute on the Exchange at a price equal to or better than, but not 
inferior to, the best away market price but, if that best away 
market remains, the DNR order will remain in the Exchange book and 
be displayed at the better of a price one minimum price variation 
away from that ABBO or the established Exchange BBO. A DNR order 
remaining on the book after the opening process or received during 
open trading that is marketable against the ABBO when the ABBO is 
better than the Exchange BBO will be exposed at the NBBO to market 
participants. Any incoming order interacting with such a resting DNR 
order will receive the best away market price. Should the best away 
market change its price, or move to an inferior price level, the DNR 
order will automatically re-price from its one minimum price 
variation away from the original away best bid/offer price to one 
minimum trading increment away from the new away best bid/offer 
price or its original limit price, and expose such orders at the 
NBBO to market participants only if the re-priced order locks or 
crosses the ABBO and is not already displayed at its limit price. 
Should the best away market improve its price such that it locks or 
crosses the DNR order limit price, the Exchange will execute the 
resulting incoming order that is routed from the away market that 
locked or crossed the DNR order limit price. An order exposure alert 
may be sent if the order size is modified.''
---------------------------------------------------------------------------

    The Exchange proposes to amend the second and third sentence of 
current BX Chapter VI, Section 11(a)(1)(C), which states,

    A DNR order may execute on the Exchange at a price equal to or 
better than, but not inferior to, the best away market price but, if 
that best away market remains, the DNR order will remain in the 
Exchange book and be displayed at the better of a price one minimum 
price variation away from that ABBO or the established Exchange BBO. 
A DNR order remaining on the book after the opening process or 
received during open trading that is marketable against the ABBO 
when the ABBO is better than the Exchange BBO will be exposed at the 
NBBO to market participants.

    The Exchange proposes to instead provide at proposed BX Chapter VI, 
Section 11(a)(iii)(A), ``A DNR Order may execute on the Exchange at a 
price equal to or better than, but not inferior to, the best away 
market price but, if that best away market remains, the DNR Order will 
remain in the BX Order Book and be displayed at a price one minimum 
price variation (``MPV'') \19\ inferior to that away best bid/offer.'' 
The Exchange is amending ``one minimum price variation away from that 
ABBO or the established Exchange BBO'' to ``one minimum price variation 
(``MPV'') inferior to that away best bid/offer.'' Further, the Exchange 
provides at proposed BX Chapter VI, Section 11(a)(iii)(A), ``If the DNR 
Order is locking or crossing the ABBO, the DNR Order shall be entered 
into the Order Book at the ABBO price and displayed one MPV away from 
the ABBO. The Exchange shall immediately expose the order at the ABBO 
to participants, provided the option series has opened for trading.'' 
An order that the Options Participant has elected not to make eligible 
for routing will be re-priced to the current national best offer (for 
bids) or the current national best bid (for offers) and displayed at 
one MPV above (for offers) or below (for bids) the national best price. 
The Exchange displays the DNR Order at one MPV away in compliance with 
Regulation NMS. An order will not be executed at a price that trades 
through another market or displayed at a price that would lock or cross 
another market. An order that is designated by a member as non-routable 
will be re-priced in order to comply with applicable Trade-Through and 
Locked and Crossed Markets restrictions.\20\ This proposed new sentence 
will add greater transparency as to the manner in which the Exchange 
handles locked and cross orders today and re-prices those orders.
---------------------------------------------------------------------------

    \19\ Any reference to minimum price variance in the rules will 
be replaced with ``MPV.''
    \20\ Also, an order that is designated by the member as routable 
will be routed in compliance with applicable Trade-Through and 
Locked and Crossed Markets restrictions.
---------------------------------------------------------------------------

    The Exchange proposes to remove the current sentence within current 
BX Chapter VI, Section 11(a)(1)(C), which provides, ``A DNR order 
remaining on the book after the opening process or received during open 
trading that is marketable against the ABBO when the ABBO is better 
than the Exchange BBO will be exposed at the NBBO to market 
participants.'' The Exchange proposes to state at proposed BX Chapter 
VI, Section 11(a)(iii)(A), ``The Exchange shall immediately expose the 
order at the ABBO to participants, provided the option series has 
opened for trading.'' The Exchange notes that inserting ``ABBO'' more 
clearly provides that the away market is considered because the local 
book has already been exhausted in this scenario. The Exchange proposes 
to amend the next sentence of current BX Chapter VI, Section 
11(a)(1)(C), which provides, ``Any incoming order interacting with such 
a resting DNR order will receive the best away market price.'' The 
Exchange proposes to instead state at proposed BX Chapter VI, Section 
11(a)(iii)(A), ``Any incoming order interacting with such a resting DNR 
order will execute at the ABBO price, unless the ABBO is improved to a 
price which crosses the DNR's displayed price, in which case the 
incoming order will execute at the previous ABBO price.'' The Exchange 
is expanding this language because it is accounting for a scenario 
where an ABBO was disseminated after the crossing condition took place. 
This is a change to reflect the current practice and amend the rule 
text to conform to the manner in which the System is operating. While 
the ABBO can improve, when it crosses the DNR Order the updated ABBO 
cannot be utilized to execute the DNR Order. The Exchange is amending 
the sentence of current BX Chapter VI, Section 11(a)(1)(C), ``Should 
the best away market change its price, or move to an inferior price 
level, the DNR order will automatically re-price from its one minimum 
price variation away from the original away best bid/offer price to one 
minimum trading increment away from the new away best bid/offer price 
or its original limit price, and expose such orders at the NBBO to 
market participants only if the re-priced order locks or crosses the 
ABBO and is not already displayed at its limit price.'' The Exchange 
proposes to state within proposed BX Chapter VI, Section 11(a)(iii)(A), 
``Should the best away market change its price to an inferior price 
level, the DNR Order will automatically re-price from its one MPV 
inferior to the original away best bid/offer price to one minimum 
trading increment away from the new away best bid/offer price or its 
original limit price, and expose such orders at the ABBO to 
participants only if the re-priced order locks or crosses the ABBO.'' 
The Exchange is rewording this sentence because the NBBO by definition 
includes the BBO. However, if the DNR order locks or crosses the BBO, 
the DNR order will immediately execute. Only if the DNR order locks or 
crosses the ABBO will the DNR order be exposed. This amendment reflects 
current practice.
    The Exchange proposes to add a new sentence to proposed Chapter VI, 
Section 11(a)(iii)(A) which states, ``Once priced at its original limit 
price, it will remain at that price until executed or cancelled.'' The 
Exchange believes the addition of this sentence, similar to rule text 
in Phlx today \21\ will add more clarity to the manner in which the DNR 
Order will be priced.
---------------------------------------------------------------------------

    \21\ See Phlx Rule 1093(a).
---------------------------------------------------------------------------

    The proposed rule text is intended to bring more clarity to the 
current rule regarding DNR Orders. The Exchange believes that adding 
context around a DNR Order when that order is locked or crossed will 
provide more transparency to the current rule. The Exchange notes that 
consistent with SEEK and SRCH Orders, a DNR Order that is locked or 
crossed will display one MPV away from the ABBO. The Exchange believes 
that the proposed language will benefit market participants because it 
provides greater information.
SEEK Order
    The Exchange proposes to relocate SEEK Orders which are currently 
within BX Chapter VI, Section 11(a)(1)(A) into proposed new BX Chapter 
VI, Section 11(a)(iii)(B).\22\
---------------------------------------------------------------------------

    \22\ Phlx does not have SEEK Orders.
---------------------------------------------------------------------------

    The first sentence of current BX Chapter VI, Section 11(a)(1)(A) is 
proposed to be relocated to proposed BX Chapter VI, Section 
11(a)(iii)(B).\23\ The Exchange proposes to add the following

[[Page 27377]]

sentence to proposed BX Chapter VI, Section 11(a)(iii)(B), ``Orders 
initiate their own route timers and are routed in the order in which 
their route timers end.'' Specifically, each order begins a separate 
Route Timer, which cannot be early terminated. Each individual order's 
Route Timer must complete before the order can route to an away market. 
The Exchange believes that this language makes clear how the SEEK Order 
is prioritized today for routing purposes, which is sequentially based 
on the Route Timer.
---------------------------------------------------------------------------

    \23\ Proposed BX Chapter VI, Section 11(a)(iii)(B) provides, 
``SEEK is a routing option pursuant to which an order will first 
check the System for available contracts for execution, and then is 
sent to other available market centers for potential execution. 
Orders initiate their own route timers and are routed in the order 
in which their route timers end.''
---------------------------------------------------------------------------

    The Exchange proposes to add new text at BX Chapter VI, Section 
11(a)(iii)(B)(1) \24\ which provides, ``If a SEEK is received during an 
Opening Process it may route as part of the Opening Cross pursuant to 
Chapter VI, Section 8(b)(7).'' The Exchange proposes to introduce the 
defined term ``Opening Process'' within proposed BX Chapter VI, Section 
11(a).\25\
---------------------------------------------------------------------------

    \24\ Proposed BX Chapter VI, Section 11(a)(iii)(B)(1) provides, 
``If a SEEK is received during an Opening Process it may route as 
part of the Opening Cross pursuant to Chapter VI, Section 8(b)(7).''
    \25\ The last sentence of the first paragraph of proposed BX 
Chapter VI, Section 11(a) provides, ``For purposes of this rule BX's 
opening process is governed by Chapter VI, Section 8 and includes an 
opening after a trading halt (``Opening Process'').''
---------------------------------------------------------------------------

    The Exchange proposes to amend current Chapter VI, Section 
11(a)(1)(A), by utilizing the defined term ``Opening Process'' instead 
of ``after the opening process or received during open trading'' and 
remove the phrase ``a Route Timer not to exceed one second'' which is 
also defined within the term Route Timer in proposed Chapter VI, 
Section 11(a). The term ``NBBO'' is being replaced with the term 
``ABBO'' because it is a more accurate representation than NBBO because 
the local market has been exhausted and this portion of the rule is 
describing the SEEK Order reacting to the ABBO. The proposed sentence 
would provide at proposed BX Chapter VI, Section 11(a)(iii)(B)(2), ``If 
a SEEK Order is received after an Opening Process and it is marketable 
against the ABBO when the ABBO is better than the displayed Exchange 
BBO, a Route Timer will initiate and expose the SEEK Order at the ABBO 
to allow market participants an opportunity to interact with the 
remainder of the SEEK Order.'' The Exchange proposes to replace the 
current sentence within current Chapter VI, Section 11(a)(1)(A), 
``During the Route Timer, the SEEK order will be included in the 
displayed Exchange BBO at the better of a price one MPV away from the 
ABBO or the established Exchange BBO.'' The Exchange proposes to state 
in its place at the end of proposed BX Chapter VI, Section 
11(a)(iii)(B)(2), ``During the Route Timer, the SEEK Order will be 
included in the displayed Exchange BBO, unless the SEEK Order locks or 
crosses the ABBO, in which case it will be entered into the Order Book 
at the ABBO price and displayed one MPV away from the ABBO.'' The 
Exchange is adding a locked and crossed scenario to the rule and 
indicating the price at which the SEEK Order would display. This 
additional information is intended to describe the condition that would 
cause the SEEK Order to reprice, the locked or crossed market.\26\
---------------------------------------------------------------------------

    \26\ Proposed BX Chapter VI, Section 11(a)(iii)(B)(2), would 
provide, ``If a SEEK Order is received after an Opening Process and 
it is marketable against the ABBO when the ABBO is better than the 
displayed Exchange BBO, a Route Timer will initiate and expose the 
SEEK Order at the ABBO to allow market participants an opportunity 
to interact with the remainder of the SEEK Order. During the Route 
Timer, the SEEK Order will be included in the displayed Exchange 
BBO, unless the SEEK Order locks or crosses the ABBO, in which case 
it will be entered into the Order Book at the ABBO price and 
displayed one MPV away from the ABBO.''
---------------------------------------------------------------------------

    Proposed BX Chapter VI, Section 11(a)(iii)(B)(3) \27\ is the same 
as the current rule text at BX Chapter VI, Section 11(a)(1)(A), however 
the Exchange proposes to amend current BX Chapter VI, Section 
11(a)(1)(A) which states, ``If, during the Route Timer, any new 
interest arrives opposite the SEEK order that is equal to or better 
than the ABBO price, the SEEK order will trade against such new 
interest at the ABBO price.'' The Exchange proposes to replace this 
sentence within proposed Chapter VI, Section 11(a)(iii)(B)(3) with, 
``If during the Route Timer, the ABBO moves and crosses the SEEK Order, 
any new interest arrives opposite the SEEK Order that is marketable 
against the SEEK Order will trade at the SEEK Order price.'' This 
scenario is not currently described in the current rule. This new 
sentence will address the specific situation where the ABBO cross a 
SEEK Order and the price at which the SEEK Order would trade. In this 
situation, the away market has crossed the BBO. The contra interest 
would therefore execute at the SEEK Order price. The new language will 
provide market participants with greater transparency as to the manner 
in which the System currently handles a SEEK Order in that particular 
situation.
---------------------------------------------------------------------------

    \27\ Proposed BX Chapter VI, Section 11(a)(iii)(B)(3) provide, 
``If during the Route Timer in subparagraph (2) above any new 
interest arrives opposite the SEEK order that is equal to or better 
than the ABBO price, the SEEK Order will trade against such new 
interest at the ABBO price. If during the Route Timer, the ABBO 
moves and crosses the SEEK Order, any new interest arrives opposite 
the SEEK Order that is marketable against the SEEK Order will trade 
at the SEEK Order price. When checking the Order Book, the System 
will seek to execute at the price at which it would send the order 
to a destination market center. Eligible unexecuted orders will 
continue to be routed as described in subparagraph (B)(2).''
---------------------------------------------------------------------------

    The Exchange proposes to amend rule text within current BX Chapter 
VI, Section 11(a)(1)(A) with proposed BX Chapter VI, Section 11(a)(4) 
\28\ by amending the first sentence from ``If contracts remain 
unexecuted after routing, they are posted on the book'' to ``If 
contracts remain unexecuted after routing, they are posted on the Order 
Book at its limit price.'' This new text seeks to makes clear the price 
at which the SEEK Order would post in the first sentence and therefore 
provides additional information which is also contained in the second 
sentence of that paragraph, which reflects current rule text. The 
remainder of proposed BX Chapter VI, Section 11(a)(4) captures current 
text within current BX Chapter VI, Section 11(a)(1)(A).
---------------------------------------------------------------------------

    \28\ Proposed BX Chapter VI, Section 11(a)(iii)(B)(4) provides, 
``If contracts remain unexecuted after routing, they are posted on 
the Order Book at its limit price. While on the Order Book at the 
limit price, should the order subsequently be locked or crossed by 
another market center, the System will not re-expose or route the 
order to the locking or crossing market center.''
---------------------------------------------------------------------------

    The Exchange proposes to delete a relocated sentence within current 
BX Chapter VI, Section 11(a)(1)(A), which provides, ``SEEK orders will 
not be eligible for routing until the next time the option series is 
subject to a new opening or reopening.'' The aforementioned sentence 
was relocated to proposed BX Chapter VI, Section 11(a) and utilizes the 
defined term ``Opening Process'' within proposed BX Chapter VI, Section 
11(a).\29\
---------------------------------------------------------------------------

    \29\ Proposed BX Chapter VI, Section 11(a)(iii)(B)(5) provides, 
``SEEK Orders will not be eligible for routing until the next time 
the option series is subject to a new Opening Process.''
---------------------------------------------------------------------------

SRCH Order
    The Exchange proposes to relocate SRCH Orders which are currently 
in BX Chapter VI, Section 11(a)(1)(B) to proposed BX Chapter VI, 
Section 11(a)(iii)(C). As noted herein, Phlx and BX SRCH Orders differ.
    The first sentence of current BX Chapter VI, Section 11(a)(1)(B) is 
proposed to be relocated to proposed BX Chapter VI, Section 
11(a)(iii)(C).\30\ The Exchange proposes to add the following second 
sentence to proposed BX

[[Page 27378]]

Chapter VI, Section 11(a)(iii)(C), ``Orders initiate their own route 
timers and are routed in the order in which their route timers end.'' 
Specifically, each order begins a separate Route Timer, which cannot be 
early terminated. Each individual order's Route Timer must complete 
before the order can route to an away market. The Exchange believes 
that this language makes clear how the SRCH Order is prioritized today 
for routing purposes, which is sequentially based on the Route Timer.
---------------------------------------------------------------------------

    \30\ Proposed BX Chapter VI, Section 11(a)(iii)(C) provides, 
``SRCH Order is a routing option pursuant to which an order will 
first check the System for available contracts for execution, and 
then is sent to other available market centers for potential 
execution. Orders initiate their own route timers and are routed in 
the order in which their route timers end.''
---------------------------------------------------------------------------

    The Exchange proposes to amend the third sentence of current BX 
Chapter VI, Section 11(a)(iii)(B) which provides, ``During the Route 
Timer, the SRCH order will be included in the displayed Exchange BBO at 
the better of a price one MPV away from the ABBO or the established 
Exchange BBO.'' The Exchange proposes the following rule text within 
proposed BX Chapter VI, Section 11(a)(iii)(C)(2),

    During the Route Timer described in subparagraph (1), the SRCH 
Order will be included in the displayed Exchange BBO, unless the 
SRCH Order locks or crosses the ABBO, in which case it will be 
entered into the Order Book at the ABBO price and displayed one MPV 
away from the ABBO. If there exists a locked market upon receipt of 
the SRCH Order, the SRCH Order may display at the locked ABBO price.

    The Exchange is adding a locked and crossed scenario to the rule 
and indicating the price at which the SRCH Order would display. This 
additional information is intended to describe the condition that would 
cause the SRCH Order to reprice the locked or crossed market.
    The Exchange proposes to relocate the fourth through sixth 
sentences of current BX Chapter VI, Section 11(a)(1)(B) to proposed BX 
Chapter VI, Section 11(a)(iii)(C)(3).\31\ The proposed new rule text is 
substantially similar to the proposed rule text except that the 
Exchange proposes to add a new sentence to this paragraph which 
provides, ``If during the Route Timer, the ABBO moves and crosses the 
SRCH Order, any new interest arrives opposite the SRCH Order that is 
marketable against the SRCH Order will trade at the SRCH Order price.'' 
This new sentence will address the specific situation where the ABBO 
cross a SRCH Order and the price at which the SRCH Order would trade. 
In this situation, the away market has crossed the BBO. The contra 
interest would therefore execute at the SRCH Order price. The new 
language will provide market participants with greater transparency as 
to the manner in which the System currently handles a SRCH Order in 
that particular situation.
---------------------------------------------------------------------------

    \31\ Proposed BX Chapter VI, Section 11(a)(iii)(C)(3) provides, 
``If, during the Route Timer described in subparagraph (1), any new 
interest arrives opposite the SRCH Order that is equal to or better 
than the ABBO price, the SRCH order will trade against such new 
interest at the ABBO price. If during the Route Timer, the ABBO 
moves and crosses the SRCH Order, any new interest arrives opposite 
the SRCH Order that is marketable against the SRCH Order will trade 
at the SRCH Order price. When checking the Order Book, the System 
will seek to execute at the price at which it would send the order 
to a destination market center. Eligible unexecuted orders will 
continue to be routed as described in subparagraph (C)(1).''
---------------------------------------------------------------------------

    The Exchange proposes to relocate and amend the seventh and eight 
sentences of current BX Chapter VI, Section 11(a)(1)(B) to proposed BX 
Chapter VI, Section 11(a)(iii)(C)(4) \32\ which state, ``If contracts 
remain un-executed after routing, they are posted on the book. Once on 
the book, should the order subsequently be locked or crossed by another 
market center, it will be re-exposed, provided it is not on the book at 
its limit price, and re-route. An order exposure alert may be sent if 
the order size is modified.'' The Exchange is adding the phrase ``at 
the limit price'' within this sentence to correctly note that the price 
at which the order is posted at on the Order Book. Further, the 
Exchange proposes to amend the penultimate sentence of current BX 
Chapter VI, Section 11(a)(1)(B) as the sentence is incorrect. The 
Exchange proposes to amend this incorrect sentence to provide at 
proposed BX Chapter VI, Section 11(a)(iii)(C)(4), ``While on the Order 
Book at the limit price, should the order subsequently be locked or 
crossed by another market center, the System will not re-expose or 
route the order to the locking or crossing market center.'' The 
Exchange notes that the current text which states that the SRCH Order 
would be re-exposed is incorrect. The current practice is that the 
order is not re-exposed because the SRCH Order is being locked or 
crossed by an away market and the Exchange is not required to re-expose 
the SRCH Order in this scenario. The final sentence of Current Chapter 
VI, Section 11(a)(i)(B) is being relocated to proposed Section 11(a) as 
noted herein.
---------------------------------------------------------------------------

    \32\ Proposed BX Chapter VI, Section 11(a)(iii)(C)(4) provides, 
``If contracts remain un-executed after routing, they are posted on 
the Order Book at its limit price. While on the Order Book at the 
limit price, should the order subsequently be locked or crossed by 
another market center, the order will not re-expose and may route at 
the end of route timer.''
---------------------------------------------------------------------------

Current Chapter VI, Section 11(a)(1)(D)
    The Exchange proposes to delete BX Chapter VI, Section 11(a)(1)(D) 
because the Exchange has relocated the locked and crossed scenarios 
into the text of SEEK and SRCH as explained herein. The proposed text 
also addresses new interest trading opposite the order as well as 
eligible unexecuted interest. The Exchange believes that this paragraph 
is unnecessary with the proposed text for SEEK and SRCH.
2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\33\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\34\ in particular, in that it is designed to 
promote just and equitable principles of trade and to protect investors 
and the public interest because the Exchange is adding more detail to 
its routing rule to provide market participants with greater 
transparency. The Exchange believes the added scenarios will provide 
more context to routing in general and for the specific routing 
strategies for the benefit of investors and the public interest. Also, 
in defining terms and utilizing consistent language throughout the 
rule, the Exchange believes the proposed rule will provide transparency 
with respect to the manner in which BX routes orders. The Exchange 
continues to offer various choices to its market participants with 
respect to routing.

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

Chapter VI, Section 11
    The Exchange's proposal to utilize the term ``System'' will conform 
this rule to other BX rules which utilize that term. Explaining the 
Route Timer at the beginning of this proposed rule will provide context 
to use of the term throughout the rule and avoid repetitiveness. 
Replacing the term ``NBBO'' with the term ``ABBO,'' where appropriate, 
is consistent with the Act because the term ``ABBO'' refers to the away 
market and not the local market, which is a more accurate term in 
situation where the local market has been exhausted. Defining minimum 
price variation and Opening Process will bring greater transparency to 
proposed Chapter IV, Section 11. The Exchange believes that it is 
consistent with the Act to refer to the Opening Process within Chapter 
VI, Section 8 when referring to routing during the Opening Process to 
avoid confusion with respect to governing rules. The Exchange's 
proposal to add the concept of DNR at the beginning of the rule to make 
clear up-front that this option is available when selecting a routing 
strategy is a structural non-substantive change intended to bring 
greater clarity to the rule.
    The Exchange proposes to more specifically explain within the rule 
text

[[Page 27379]]

what is meant by ``exposure'' or ``exposing'' an order. The Exchange 
proposes to make clear that exposure shall mean a notification sent to 
participants that includes the price, size, and side of interest that 
is available for execution. The Exchange believes that this additional 
language in consistent with the Act because it will assist market 
participants in understanding the manner in which these terms are used 
throughout this rule.
    The Exchange's proposal to not disseminate an exposure notification 
to participants if an incoming order is joining an already established 
BBO price when the ABBO is locked or crossed with the BBO is consistent 
with the Act because in this case, such order will join the established 
BBO price, which is already disseminated. The Exchange believes that 
exposing an order which reflects a disseminated price could cause 
confusion rather than inform investors and the general public of the 
availability of an order. Today, the Exchange executes responses at a 
price at or better than the ABBO on a first come, first served basis 
prior to routing the order to an away market in accordance with the 
rules currently in effect in Chapter VI, Section 11. If a response is 
received which is executable against the full volume of the order, it 
may execute immediately. Since the order was filled, the Route Timer no 
longer exists because the order no longer exists. The Exchange believes 
that this notification is not necessary in the case of an incoming 
order that joins an already established BBO price when the ABBO is 
locked or crossed with the BBO as other orders previously established 
the BBO on the Order Book. The established BBO price is a disseminated 
price which is available to market participants. A second notification 
with the exposure message would reflect the same price as the 
disseminated BBO price and would not offer market participants new 
information.
    The remainder of the rule changes in the introduction are non-
substantive rule changes that simply seek to reorganize and add 
transparency to the current rule text.
DNR Orders
    The Exchange's proposal to add a new sentence to proposed new 
Chapter VI, Section 11(a)(iii)(A), that is not in the current rule 
text, that provides, ``If the DNR order is locking or crossing the 
ABBO, the DNR order shall be entered into the Order Book at the ABBO 
price and displayed one MPV away from the ABBO'' is consistent with the 
Act because this behavior is compliant with Regulation NMS. An order 
will not be executed at a price that trades through another market or 
displayed at a price that would lock or cross another market. An order 
that is designated by a member as non-routable will be re-priced in 
order to comply with applicable Trade-Through and Locked and Crossed 
Markets restrictions.\35\ The Exchange's proposal to account for a 
scenario where an ABBO was disseminated after the crossing condition 
took place is consistent with the Act because an updated ABBO that 
crosses the DNR Order cannot be utilized to execute the DNR Order. The 
Exchange believes that adding context around a DNR Order when that 
order is locked or crossed will provide more transparency to the rule. 
The Exchange notes that consistent with SEEK and SRCH Orders, a DNR 
Order that is locked or crossed will display one MPV away from the 
ABBO. The Exchange believes that the proposed language will benefit 
market participants because it provides greater information.
---------------------------------------------------------------------------

    \35\ Also, an order that is designated by the member as routable 
will be routed in compliance with applicable Trade-Through and 
Locked and Crossed Markets restrictions.
---------------------------------------------------------------------------

    The Exchange's proposal to remove the sentence within current BX 
Chapter VI, Section 11(a)(1)(C) which provides, ``A DNR order remaining 
on the book after the opening process or received during open trading 
that is marketable against the ABBO when the ABBO is better than the 
Exchange BBO will be exposed at the NBBO to market participants'' and 
instead provide within proposed BX Chapter VI Section 11(a)(iii)(A), 
``The Exchange shall immediately expose the order at the ABBO to 
participants, provided the option series has opened for trading'' is 
consistent with the Act. The Exchange notes that inserting ``ABBO'' 
more clearly provides that the away market is considered because the 
local book has already been exhausted in this scenario. This amendment 
will protect investors and the public interest by avoiding confusion. 
Adding locking and crossing scenarios will account for a scenario where 
an ABBO was disseminated after the crossing condition took place. This 
is a change to reflect the current practice and amend the rule text to 
conform to the manner in which the System is operating. While the ABBO 
can improve, when it crosses the DNR Order the updated ABBO cannot be 
utilized to execute the DNR Order. The Exchange's proposal to amend 
rule text, within proposed BX Chapter VI Section 11(a)(iii)(A) to 
provide, ``Should the best away market change its price to an inferior 
price level, the DNR Order will automatically re-price from one MPV 
inferior to the original away best bid/offer price to one minimum 
trading increment away from the new away best bid/offer price or its 
original limit price, and expose such orders at the ABBO to 
participants only if the re-priced order locks or crosses the ABBO'' is 
consistent with the Act. The Exchange is rewording this sentence 
because the NBBO by definition includes the BBO. However, if the DNR 
order locks or crosses the BBO, the DNR order will immediately execute. 
Only if the DNR order locks or crosses the ABBO will the DNR order be 
exposed. The proposed rule text is intended to bring more clarity to 
the current rule regarding DNR Orders. The Exchange believes that 
adding context around a DNR Order when that order is locked or crossed 
will provide more transparency to the current rule. The Exchange 
believes that the proposed language will benefit market participants 
because it provides greater information.
    The Exchange's proposal to add a new sentence to proposed Chapter 
VI, Section 11(a)(iii)(A), ``Once priced at its original limit price, 
it will remain at that price until executed or cancelled'' is 
consistent with the Act. The Exchange believes the addition of this 
sentence, similar to rule text in Phlx today \36\ will add more clarity 
to the manner in which the DNR Order will be priced.
---------------------------------------------------------------------------

    \36\ See Phlx Rule 1093(a).
---------------------------------------------------------------------------

SEEK and SRCH Orders
    The Exchange's proposal to expand the current language within SEEK 
and SRCH Orders to add a reference to an Opening Process as defined 
within proposed BX Chapter VI, Section 11(a) will add clarity to the 
rule text. Also, making clear that each order begins a separate Route 
Timer, which cannot be early terminated and the individual order's 
Route Timer must complete before the order can route to an away market 
is consistent with the Act because the Exchange is allowing the entire 
time on the Route Timer to obtain the best price for the order.\37\ In 
order to maintain priority within the System, the SEEK and SRCH Order 
is prioritized today for routing purposes, which is sequentially based 
on the Route Timer.
---------------------------------------------------------------------------

    \37\ See proposed BX Rule Chapter VI, Sections 11(a)(iii)(B) and 
11(a)(iii)(C).
---------------------------------------------------------------------------

SEEK Order
    The Exchange's proposal to utilize the more precise terms ``ABBO'' 
in place of ``NBBO'' where the local market has been exhausted when 
describing SEEK

[[Page 27380]]

Order behavior is consistent with the Act because the term is more 
accurate.\38\ The Exchange's proposal to note a scenario where the ABBO 
moves and crosses the SEEK Order during a Route Timer.\39\ If the away 
market price crosses the BBO, the market is crossed and contra interest 
would execute at the price the order rested on the Order Book. If the 
away price locks the displayed price, the contra interest would execute 
at its displayed price. This proposed rule text is consistent with the 
Act because it would not permit a trade-through but would allow a SEEK 
Order to trade where the order is marketable, but does not trade-
though. The new language will provide market participants with greater 
transparency as to the manner in which the System will handle a SEEK 
Order in that particular situation. This is also applicable to SRCH 
Orders.
---------------------------------------------------------------------------

    \38\ See proposed BX Chapter VI, Section 11(a)(1)(A).
    \39\ See proposed BX Chapter VI, Section 11(a)(iii)(B)(2).
---------------------------------------------------------------------------

SRCH Order
    The Exchange's proposal to add new rule text within proposed BX 
Chapter VI, Section 11(a)(iii)(C)(3) concerning a SRCH Order, ``If 
during the Route Timer, the ABBO moves and crosses the SRCH Order, any 
new interest arrives opposite the SRCH Order that is marketable against 
the SRCH Order will trade at the SRCH Order price'' is consistent with 
the Act. This new sentence will address the specific situation where 
the ABBO cross a SRCH Order and the price at which the SRCH Order would 
trade. In this situation, the away market has crossed the BBO. The 
contra interest would therefore execute at the SRCH Order price. The 
new language will provide market participants with greater transparency 
as to the manner in which the System currently handles a SRCH Order in 
that particular situation'' \40\ is consistent with the Act because 
this situation accounts for a locked and crossed market scenario and 
provides information as to the manner in which the SRCH Order would 
display. This information provides market participant with greater 
transparency.
---------------------------------------------------------------------------

    \40\ See proposed BX Chapter VI, Section 11(a)(iii)(C)(3).
---------------------------------------------------------------------------

    The Exchange's proposal to amend the penultimate sentence of 
current BX Chapter VI, Section 11(a)(1)(B) to provide, ``While on the 
Order Book at the limit price, should the order subsequently be locked 
or crossed by another market center, the order will not re-expose and 
may route at the end of route timer'' is consistent with the Act 
because the Exchange would not disseminate an exposure notification to 
participants because the SRCH Order is being locked or crossed by an 
away market and the Exchange is not required to re-expose the SRCH 
Order in this scenario.
Current Chapter VI, Section 11(a)(1)(D)
    The Exchange's proposal to delete current BX Chapter VI, Section 
11(a)(1)(D) is consistent with the Act because the Exchange has 
relocated the locked and crossed scenarios into the text of SEEK and 
SRCH as explained herein. The proposed text also addresses new interest 
trading opposite the order as well as eligible unexecuted interest. The 
Exchange believes that this paragraph is unnecessary and redundant in 
light of the proposed text for SEEK and SRCH.

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 not necessary or appropriate in 
furtherance of the purposes of the Act. The proposed routing rules 
apply to all market participants including routing during an Opening 
Process. The Exchange believes that adding greater detail to its rules 
does not impose an undue burden on competition, rather it provides 
greater transparency as to the potential outcomes when utilizing 
different routing strategies. Further, the Exchange notes that market 
participants may elect not to route their orders. The Exchange 
continues to offer various options to its market participants with 
respect to routing.

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

    No written comments were either solicited or received.

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) of the Act \41\ and Rule 19b-
4(f)(6) thereunder.\42\
---------------------------------------------------------------------------

    \41\ 15 U.S.C. 78s(b)(3)(A).
    \42\ 17 CFR 240.19b-4(f)(6). In addition, Rule 19b-4(f)(6)(iii) 
requires a self-regulatory organization to give the Commission 
written notice of its intent to file the proposed rule change, along 
with a brief description and text of 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 pursuant to Rule 19b-4(f)(6) under the 
Act \43\ normally does not become operative for 30 days after the date 
of its filing. However, Rule 19b-4(f)(6)(iii) \44\ permits the 
Commission to designate a shorter time if such action is consistent 
with the protection of investors and the public interest. The Exchange 
has requested that the Commission waive the 30-day operative delay so 
that the proposed rule change may become operative upon filing. The 
Commission believes that waiving the 30-day operative delay is 
consistent with the protection of investors and the public interest, as 
it will allow the Exchange to immediately provide members with greater 
information and transparency on potential order routing strategies 
available on the Exchange. For this reason, the Commission hereby 
waives the 30-day operative delay and designates the proposed rule 
change as operative upon filing.\45\
---------------------------------------------------------------------------

    \44\ 17 CFR 240.19b-4(f)(6)(iii).
    \45\ For purposes only of waiving the 30-day operative delay, 
the Commission also has 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 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 shall institute proceedings to 
determine whether the proposed rule change should be approved or 
disapproved.

IV. Solicitation of Comments
