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

    The Exchange proposes to amend Supplementary Material .02 to Rule 
715 regarding Cancel and Replace Orders.
    The text of the proposed rule change is available on the Exchange's 
website at http://nasdaqmrx.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 Supplementary Material .02 to Rule 
715 regarding Cancel and Replace Orders to: (i) Correct an 
inconsistency between the Exchange's rule text and the operation of the 
System \3\ by removing the reference to Rule 710, (ii) update rule 
cross-references, and (iii) make other non-substantive, technical 
changes.
---------------------------------------------------------------------------

    \3\ The term ``System'' means the electronic system operated by 
the Exchange that receives and disseminates quotes, executes orders 
and reports transactions. See Rule 100(a)(66).
---------------------------------------------------------------------------

    Today, a member has the option of either sending in a cancel order 
and then separately sending in a new order which serves as a 
replacement of the original order (two separate messages), or sending a 
single cancel and replace order in one message (i.e., a Cancel and 
Replace Order). Specifically, Supplementary Material .02 to Rule 715 
defines a Cancel and Replace Order as a single message for the 
immediate cancellation of a previously received order and the 
replacement of that order with a new order.\4\ The replacement portion 
of the Cancel and Replace Order is treated as a new order and therefore 
goes through price or other reasonability checks as a result of being 
viewed as such.\5\ If the replacement portion of a Cancel and Replace 
Order does not satisfy the System's price or other reasonability 
checks, the existing order will be cancelled and not replaced.\6\ The 
Exchange notes, however, that when it initially codified Cancel and 
Replace Orders in its Rulebook as part of SR-MRX-2017-02, it 
inadvertently included Rule 710 within the list of price reasonability 
checks. In SR-MRX-2017-02, the Exchange explained that the System 
conducts price or other reasonability checks for Cancel and Replace 
Orders to validate such orders against the current market conditions 
prior to proceeding with the request to modify the order.\7\ Rule 710, 
which relates to the minimum price variations applicable to options 
series traded on the Exchange, does not involve the System considering 
the current market at the time of the Cancel and Replace Order, and an 
incoming Cancel and Replace Order that fails the minimum price 
variation checks in Rule 710 would not result in the existing order 
being cancelled and not replaced.\8\ The Exchange therefore proposes to 
remove the reference to Rule 710 from the list of price or other 
reasonability checks to conform its rule text to the System. The 
Exchange also proposes to update the various rule references related to 
the price reasonability checks within this provision to refer to the 
current rules.\9\ Finally, the Exchange proposes other non-substantive, 
technical changes within Supplementary Material .02 to Rule 715 to 
capitalize ``Cancel and Replace Order'' for consistency, and to 
capitalize ``System,'' which is a defined term.
---------------------------------------------------------------------------

    \4\ If the previously placed order is already filled partially 
or in its entirety, the replacement order is automatically cancelled 
or reduced by the number of contracts that were executed. See 
Supplementary Material .02 to Rule 715.
    \5\ Supplementary Material .02 to Rule 715 further provides how 
the replacement portion may retain the priority of the original 
order, provided certain specified conditions are met. The manner in 
which the Exchange treats priority with respect to Cancel and 
Replace Orders is not changing under this proposal.
    \6\ See Securities Exchange Act Release No. 81204 (July 25, 
2017), 82 FR 35557 (July 31, 2017) (SR-MRX-2017-02) (memorializing 
Cancel and Replace Orders in Supplementary Material .02 to Rule 715 
as part of the Exchange's system migration).
    \7\ Id.
    \8\ In this instance, the System would simply reject the cancel 
and replace message as an invalid instruction. The Exchange notes 
that the previous T7 system likewise treated Cancel and Replace 
Orders in this manner.
    \9\ In particular, Rules 711(c) and 714(b)(2) are now Rules 
714(b)(1)(B) and 714(b)(1)(A), respectively, pursuant to SR-MRX-
2018-30. See Securities Exchange Act Release No. 84239 (September 
20, 2018), 83 FR 48670 (September 26, 2018).
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that its proposal is consistent with Section 
6(b) of the Act,\10\ in general, and furthers the objectives of Section 
6(b)(5) of the Act,\11\ 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. The Exchange's proposal corrects an inadvertent error in 
Supplementary Material .02 to Rule 715, which currently includes Rule 
710 within the list of price or other reasonability checks. As 
discussed above, including Rule 710 is inconsistent with the operation 
of the Exchange's System because an incoming Cancel and Replace Order 
which fails the minimum price variation checks in Rule 710 does not 
result in the existing order getting cancelled and not replaced. This 
rule change would amend the rule text to reflect MRX's current 
practice, and should avoid potential confusion about how the System 
processes Cancel and Replace Orders today.\12\ Furthermore, the 
Exchange's proposal to update the rule references and make other non-
substantive technical changes, as further described above, will bring 
greater transparency to its Rulebook thereby protecting investors and 
the public interest by reducing potential for investor confusion.

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. All of the proposed changes are 
intended to bring greater transparency to the Exchange's Rulebook, and 
therefore does not unduly burden competition.

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 \13\ and 
subparagraph (f)(6) of Rule 19b-4 thereunder.\14\
---------------------------------------------------------------------------

    \13\ 15 U.S.C. 78s(b)(3)(A)(iii).
    \14\ 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. 
At the Exchange's request, the Commission has waived this 
requirement.
---------------------------------------------------------------------------

    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 should be approved or disapproved.
