Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 7 17 CFR 200.30–3(a)(12). VerDate Sep<11>2014 22:28 Nov 01, 2017 Jkt 244001 (‘‘Act’’),1 and Rule 19b–4 thereunder,2 notice is hereby given that on October 18, 2017, Nasdaq MRX, LLC (‘‘MRX’’ 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 the Substance of the Proposed Rule Change The Exchange proposes to memorialize an optional Kill Switch protection.3 The Kill Switch allows Members to cancel open orders and prevent new order submission. The text of the proposed rule change is available on the Exchange’s Web site at www.ise.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 memorialize its Kill Switch risk protection which is applicable to all Members at MRX Rule 711(d). The Kill Switch allows Members to cancel open orders and prevent new order submission. This feature provides Members with a powerful risk management tool for immediate control of their order activity. 1 15 U.S.C. 78s(b)(1). CFR 240.19b–4. 3 Today, this feature is offered to Members. MRX transitioned from its legacy trading system to INET, the current technology, in 2017. While MRX offered this feature on its legacy system, the feature was not codified in the MRX Rulebook. At this time, the Exchange is codifying the Kill Switch feature to reflect the functionality. 2 17 PO 00000 Frm 00070 Fmt 4703 Sfmt 4703 The Kill Switch is an optional tool that enables Members to initiate a message(s) 4 [sic] to the trading system (‘‘System’’) to promptly cancel orders and restrict entry of new orders until reentry has been enabled. Members may submit a request to the System to cancel orders for that Member. Members may not remove orders by symbol using the Kill Switch. The System will send an automated message to the Member when a Kill Switch request has been processed by the Exchange’s System.5 The Member must send a message to the Exchange to request the cancellation of all orders for the Member. The Member is unable to enter additional orders until re-entry has been enabled pursuant to subsection (d)(2) of Rule 711. Proposed subsection (d)(2) stipulates that after orders are cancelled by the Member utilizing the Kill Switch, the Member is unable to enter additional orders until the Member has made a request to the Exchange and Exchange staff has set a re-entry indicator to enable re-entry.6 Once enabled for reentry, the System will send a Re-entry Notification Message to the Member. The applicable Clearing Member for that Member also is notified of the re-entry into the System after orders are cancelled as a result of the Kill Switch, provided the Clearing Member has requested to receive such notification. 2. Statutory Basis The Exchange believes that its proposal is consistent with Section 6(b) of the Act 7 in general, and furthers the objectives of Section 6(b)(5) of the Act 8 in particular, in that it is designed to promote just and equitable principles of trade, 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, by memorializing a risk protection available to Exchange Members. This risk feature promotes policy goals of the Commission which has encouraged execution venues, exchange and nonexchange alike, to offer risk protection tools and other mechanisms to decrease risk and increase stability. The 4 Members are able to send a message to the Exchange to initiate the Kill Switch or they may contact the Exchange directly. A message to remove orders may be sent through FIX, OTTO or Precise. 5 Opening Sweep Orders will also be cancelled. Consistent with current auction functionality, PIM auction orders and responses will not be cancelled. See MRX Rule 723. Other auctions orders and responses would cancel. Quotes are unaffected. 6 The Member must directly and verbally contact the Exchange to request the re-set. 7 15 U.S.C. 78f(b). 8 15 U.S.C. 78f(b)(5). E:\FR\FM\02NON1.SGM 02NON1 asabaliauskas on DSKBBXCHB2PROD with NOTICES Federal Register / Vol. 82, No. 211 / Thursday, November 2, 2017 / Notices Exchange believes that memorializing this feature will provide Members with specific information on cancelling orders. The individual firm benefits of enhanced risk protections flow downstream to counter-parties both at the Exchange and at other options exchanges, thereby increasing systemic protections as well. This risk feature allows Members to enter orders without fear of inadvertent exposure to excessive risk, which in turn benefits investors through increased liquidity for the execution of their orders, thereby protecting investors and the public interest. By memorializing the features in this rule change, Members are aware of the impact of utilizing this risk tool. This optional risk tool as noted above is offered to all Members. The Exchange further represents that its proposal operates consistently with the firm quote obligations of a broker-dealer pursuant to Rule 602 of Regulation NMS and that the functionality is not mandatory. Specifically, any interest that is executable against a Member’s orders that are received 9 by the Exchange, prior to the time the Kill Switch is processed by the System, will automatically execute at the price up to the Member’s size prior to the removal of orders from the System as a result of the Kill Switch. The Kill Switch message is accepted by the System in the order of receipt in the queue and is processed in that order so that interest that is already accepted into the System is processed prior to the Kill Switch message. With respect to providing information regarding the cancellation of orders as a result of the Kill Switch to the Clearing Member, each Member that transacts through a Clearing Member on the Exchange accepts financial responsibility for all Exchange transactions made by the Member on whose behalf the Clearing Member agrees to clear.10 The Exchange believes that because Clearing Members guarantee all transactions on behalf of a Member, and therefore bear the risk associated with those transactions, it is appropriate for Clearing Members to have knowledge of the utilization by the member [sic] of the Kill Switch, should the Clearing Member request such notification. B. Self-Regulatory Organization’s Statement on Burden on Competition The Exchange does not believe that the proposed rule change will impose 9 The time of receipt for an order is the time such message is processed by the Exchange Order Book. 10 See MRX Rule 808(b). VerDate Sep<11>2014 22:28 Nov 01, 2017 Jkt 244001 any burden on competition not necessary or appropriate in furtherance of the purposes of the Act. The proposal does not impose an undue burden on intra-market competition because all Members may avail themselves of the Kill Switch. The Kill Switch functionality is optional. The proposed rule change protects Members in the event the Member is suffering from a systems issue or from the occurrence of unusual or unexpected market activity that would require them to withdraw from the market in order to protect investors. Utilizing this Kill Switch will permit the Member to protect itself from inadvertent exposure to excessive risk. Reducing such risk will enable Members to enter orders without fear of inadvertent exposure to excessive risk, which in turn will benefit investors through increased liquidity for the execution of their orders. Such increased liquidity benefits investors because they receive better prices and because it lowers volatility in the options market. For these reasons, the Exchange does not believe this proposal imposes an undue burden on intermarket competition because other exchanges offer the same functionality, which is being memorialized herein. 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)(iii) of the Act 11 and subparagraph (f)(6) of Rule 19b–4 thereunder.12 A proposed rule change filed under Rule 19b–4(f)(6) normally does not become operative before 30 days from the date of the filing. However, pursuant to Rule 19b–4(f)(6)(iii),13 the Commission may designate a shorter time if such action is consistent with the protection of investors and the public interest. 11 15 U.S.C. 78s(b)(3)(A)(iii). CFR 240.19b–4(f)(6). 13 17 CFR 240.19b–4(f)(6)(iii). 12 17 PO 00000 Frm 00071 Fmt 4703 Sfmt 4703 50925 The Exchange has asked the Commission to waive the 30-day operative delay. The Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because the proposal is similar to the rules of other options exchanges and the Exchange’s proposal does not raise any new or novel issues. Therefore, the Commission hereby waives the 30-day operative delay and designates the proposed rule change to be operative upon filing with the Commission.14 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: (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. IV. Solicitation of Comments Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act. Comments may be submitted by any of the following methods: Electronic Comments • Use the Commission’s Internet comment form (https://www.sec.gov/ rules/sro.shtml); or • Send an email to rule-comments@ sec.gov.

At this time, the Exchange proposes to remove those references to ‘‘Nasdaq Options Services’’ and ‘‘NOS’’ and were applicable change those references to ‘‘Nasdaq Execution Services’’ or ‘‘NES’’ if the entity is not already mentioned. Also, the Exchange proposes to make grammatical changes to the current sentence to accommodate the removal of the entity. No other changes are being proposed in this filing.

(``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given that 
on October 18, 2017, Nasdaq MRX, LLC (``MRX'' or ``Exchange'') filed 
with the Securities and Exchange Commission (``SEC'' or ``Commission'')

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 the 
Substance of the Proposed Rule Change

    The Exchange proposes to memorialize an optional Kill Switch 
protection.\3\ The Kill Switch allows Members to cancel open orders and 
prevent new order submission.
---------------------------------------------------------------------------

    \3\ Today, this feature is offered to Members. MRX transitioned 
from its legacy trading system to INET, the current technology, in 
2017. While MRX offered this feature on its legacy system, the 
feature was not codified in the MRX Rulebook. At this time, the 
Exchange is codifying the Kill Switch feature to reflect the 
functionality.
---------------------------------------------------------------------------

    The text of the proposed rule change is available on the Exchange's 
Web site at www.ise.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 memorialize its Kill Switch risk 
protection which is applicable to all Members at MRX Rule 711(d). The 
Kill Switch allows Members to cancel open orders and prevent new order 
submission. This feature provides Members with a powerful risk 
management tool for immediate control of their order activity.
    The Kill Switch is an optional tool that enables Members to 
initiate a message(s) \4\ [sic] to the trading system (``System'') to 
promptly cancel orders and restrict entry of new orders until re-entry 
has been enabled. Members may submit a request to the System to cancel 
orders for that Member. Members may not remove orders by symbol using 
the Kill Switch. The System will send an automated message to the 
Member when a Kill Switch request has been processed by the Exchange's 
System.\5\
---------------------------------------------------------------------------

    \4\ Members are able to send a message to the Exchange to 
initiate the Kill Switch or they may contact the Exchange directly. 
A message to remove orders may be sent through FIX, OTTO or Precise.
    \5\ Opening Sweep Orders will also be cancelled. Consistent with 
current auction functionality, PIM auction orders and responses will 
not be cancelled. See MRX Rule 723. Other auctions orders and 
responses would cancel. Quotes are unaffected.
---------------------------------------------------------------------------

    The Member must send a message to the Exchange to request the 
cancellation of all orders for the Member. The Member is unable to 
enter additional orders until re-entry has been enabled pursuant to 
subsection (d)(2) of Rule 711.
    Proposed subsection (d)(2) stipulates that after orders are 
cancelled by the Member utilizing the Kill Switch, the Member is unable 
to enter additional orders until the Member has made a request to the 
Exchange and Exchange staff has set a re-entry indicator to enable re-
entry.\6\ Once enabled for re-entry, the System will send a Re-entry 
Notification Message to the Member. The applicable Clearing Member for 
that Member also is notified of the re-entry into the System after 
orders are cancelled as a result of the Kill Switch, provided the 
Clearing Member has requested to receive such notification.
---------------------------------------------------------------------------

    \6\ The Member must directly and verbally contact the Exchange 
to request the re-set.
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act \7\ in general, and furthers the objectives of Section 
6(b)(5) of the Act \8\ in particular, in that it is designed to promote 
just and equitable principles of trade, 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, 
by memorializing a risk protection available to Exchange Members. This 
risk feature promotes policy goals of the Commission which has 
encouraged execution venues, exchange and non-exchange alike, to offer 
risk protection tools and other mechanisms to decrease risk and 
increase stability. The

[[Page 50925]]

Exchange believes that memorializing this feature will provide Members 
with specific information on cancelling orders.

    \8\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The individual firm benefits of enhanced risk protections flow 
downstream to counter-parties both at the Exchange and at other options 
exchanges, thereby increasing systemic protections as well. This risk 
feature allows Members to enter orders without fear of inadvertent 
exposure to excessive risk, which in turn benefits investors through 
increased liquidity for the execution of their orders, thereby 
protecting investors and the public interest. By memorializing the 
features in this rule change, Members are aware of the impact of 
utilizing this risk tool.
    This optional risk tool as noted above is offered to all Members. 
The Exchange further represents that its proposal operates consistently 
with the firm quote obligations of a broker-dealer pursuant to Rule 602 
of Regulation NMS and that the functionality is not mandatory. 
Specifically, any interest that is executable against a Member's orders 
that are received \9\ by the Exchange, prior to the time the Kill 
Switch is processed by the System, will automatically execute at the 
price up to the Member's size prior to the removal of orders from the 
System as a result of the Kill Switch. The Kill Switch message is 
accepted by the System in the order of receipt in the queue and is 
processed in that order so that interest that is already accepted into 
the System is processed prior to the Kill Switch message.
---------------------------------------------------------------------------

    \9\ The time of receipt for an order is the time such message is 
processed by the Exchange Order Book.
---------------------------------------------------------------------------

    With respect to providing information regarding the cancellation of 
orders as a result of the Kill Switch to the Clearing Member, each 
Member that transacts through a Clearing Member on the Exchange accepts 
financial responsibility for all Exchange transactions made by the 
Member on whose behalf the Clearing Member agrees to clear.\10\ The 
Exchange believes that because Clearing Members guarantee all 
transactions on behalf of a Member, and therefore bear the risk 
associated with those transactions, it is appropriate for Clearing 
Members to have knowledge of the utilization by the member [sic] of the 
Kill Switch, should the Clearing Member request such notification.
---------------------------------------------------------------------------

    \10\ See MRX Rule 808(b).
---------------------------------------------------------------------------

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 proposal does not impose an 
undue burden on intra-market competition because all Members may avail 
themselves of the Kill Switch. The Kill Switch functionality is 
optional. The proposed rule change protects Members in the event the 
Member is suffering from a systems issue or from the occurrence of 
unusual or unexpected market activity that would require them to 
withdraw from the market in order to protect investors. Utilizing this 
Kill Switch will permit the Member to protect itself from inadvertent 
exposure to excessive risk. Reducing such risk will enable Members to 
enter orders without fear of inadvertent exposure to excessive risk, 
which in turn will benefit investors through increased liquidity for 
the execution of their orders. Such increased liquidity benefits 
investors because they receive better prices and because it lowers 
volatility in the options market. For these reasons, the Exchange does 
not believe this proposal imposes an undue burden on inter-market 
competition because other exchanges offer the same functionality, which 
is being memorialized herein.

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)(iii) of the Act \11\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\12\

    A proposed rule change filed under Rule 19b-4(f)(6) normally does 
not become operative before 30 days from the date of the filing. 
However, pursuant to Rule 19b-4(f)(6)(iii),\13\ the Commission may 
designate a shorter time if such action is consistent with the 
protection of investors and the public interest.

    The Exchange has asked the Commission to waive the 30-day operative 
delay. The Commission believes that waiving the 30-day operative delay 
is consistent with the protection of investors and the public interest 
because the proposal is similar to the rules of other options exchanges 
and the Exchange's proposal does not raise any new or novel issues. 
Therefore, the Commission hereby waives the 30-day operative delay and 
designates the proposed rule change to be operative upon filing with 
the Commission.\14\
---------------------------------------------------------------------------

    \14\ For purposes only of waiving the operative delay for this 
proposal, the Commission 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: (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.
