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

    National Stock Exchange, Inc. (``NSX[supreg]'' or ``Exchange'') is 
proposing to enable a Replace Message to be used to modify the display 
quantity of a Reserve Order (as defined in Rule 11.11(c)(2)), and 
proposes certain other conforming changes to its rules.
    The text of the proposed rule change is available on the Exchange's 
Web site at http://www.nsx.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 those statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
sections A, B, and C below, of the most significant parts of such 
statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    With this rule change, the Exchange is proposing to enable the 
Replace Message under NSX Rule 11.11(d) to be used to modify the 
display quantity of a Reserve Order (as defined in Rule 11.11(c)(2)). 
In addition, certain conforming modifications to the text and 
interpretation of Rule 11.14(a)(2) are proposed.
    The proposed rule change would allow the Exchange's current 
``Cancel/Replace'' order modifier functionality under Rule 11.11(d) to 
apply to the display quantity of Reserve Orders (such field being Tag 
111 \3\). Currently, the Cancel/Replace functionality under Rule 
11.11(d)(iii) allows only an adjustment to an order's price and 
quantity. As applied to Reserve Orders, the Exchange's trading system 
currently allows a Replace Message to be used to adjust only the 
reserve quantity, but not the display quantity. The proposed rule 
change would allow ETP Holders the ability to use the Replace Message 
to also adjust the display quantity of Reserve Orders (the Tag 111 
field). Under the proposed rule change, the Replace Message could 
adjust both the display and non-display portion of a Reserve Order, 
including where the aggregate size of the order remains unchanged. 
Accordingly, the instant rule filing proposes to add an explanatory 
``Interpretation and Policy'' to Rule 11.11(d) to clarify that the term 
``quantity term'' in Rule 11.11(d)(iii) shall include either, or both, 
the display and non-display portion of a Reserve Order, including in 
cases where the aggregate size of the Reserve Order is not changed. The 
identical use of the Replace Message to adjust the Tag 111 field is 
similarly offered by at least one other exchange.\4\
---------------------------------------------------------------------------

    \3\ Tag 111, also known as Max Floor, is a standard FIX 
protocol.
    \4\ See DirectEdge (EDGA and EDGX) Rule 11.5(e) and DirectEdge 
FIX Specifications Version 1.11 (http://www.directedge.com/Portals/0/docs/Direct%20Edge%20Next%20Gen%20FIX%20Manual.pdf ), at section 
3.6.2 (providing that the Cancel/Replace functionality may be used 
to modify tag 111 (the displayed quantity of a Reserve Order)). The 
Exchange notes that, unlike the text of the cancel/replace rules of 
DirectEdge, the use of the Replace Message to adjust Tag 111 under 
the instant rule filing is proposed to be reflected in an 
Interpretation and Policy to NSX Rule 11.11(e) and not only in the 
Exchange's FIX specification.
---------------------------------------------------------------------------

    The instant rule change also proposes to modify the language of NSX 
Rule 11.14 (Priority of Orders) with respect to how the use of cancel/
replace affects an order's priority. The instant rule filing modifies 
Rule 11.14(a)(2) to provide that, where the quantity of an order has 
been reduced pursuant to a Replace Message, such order maintains price/
time priority. This constitutes no changes to current Exchange system 
practice and is consistent with the trading systems of other 
markets.\5\ An Interpretation and Policy is also proposed to be added 
to rule 11.14 to clarify how a Reserve Order's priority is impacted by 
quantity adjustments (to either the display or the non-display portion) 
through use of a Replace Message. Specifically, Interpretation and 
Policy .01 provides that a Replace Message's size decrement of a 
Reserve Order's display quantity (Tag 111) will not affect the order's 
priority only if total order size remains the same or decreases. 
Similarly, a Replace Message size decrement of a Reserve Order's total 
quantity will not affect the order's priority only if the display 
quantity also remains constant or decreases. Any increase in size of 
either the display portion or the total size of a Reserve Order will 
result in a new timestamp and cause that order to lose time priority.

(EDGA and EDGX) Rule 11.8(a)(4); Arca Rule 7.36(a)(3); and CBOE Rule 
52.1(e).

    The following chart summarizes the above-described impact on a 
Reserve Order's time priority, if any, due to the use of a Replace 
Message to adjust the quantity.

[[Page 19172]]

    The following examples illustrate the effect on a Reserve Order's 
time priority, if any, due to the use of a Replace Message to adjust 
the quantity. Each example assumes ETP Holder A has a first-in-time 
priority resting Reserve Order to sell 1000 shares total, with a 
display quantity of 500 (denoted as ``1000/500'').
    Example 1 (Tag 111 Increases, Total Order Increases):
    ETP Holder A submits a Replace Message to adjust quantity to 1100/
600.
    Example 1 Result: The order loses time priority because display 
quantity is increased.
    Example 2 (Tag 111 Increases, Total Order Decreases):
    ETP Holder A submits a Replace Message to adjust quantity to 900/
600.
    Example 2 Result: The order loses time priority because display 
quantity is increased, notwithstanding that total quantity is 
decreased.
    Example 3 (Tag 111 Increases, Total Order Remains Same):
    ETP Holder A submits a Replace Message to adjust quantity to 1000/
600.
    Example 3 Result: The order loses time priority because display 
quantity is increased, notwithstanding that total quantity remains the 
same.
    Example 4 (Tag 111 Decreases, Total Order Increases):
    ETP Holder A submits a Replace Message to adjust quantity to 1100/
300.
    Example 4 Result: The order loses time priority because total 
quantity is increased, notwithstanding that display quantity is 
decreased.
    Example 5 (Tag 111 Decreases, Total Order Decreases):
    ETP Holder A submits a Replace Message to adjust quantity to 800/
400.
    Example 5 Result: The order's time priority is maintained because 
display quantity is decreased and total quantity is not increased.
    Example 6 (Tag 111 Decreases, Total Order Remains Same):
    ETP Holder A submits a Replace Message to adjust quantity to 1000/
400.
    Example 6 Result: The order's time priority is maintained because 
display quantity is decreased and total quantity is not increased.
    Example 7 (Tag 111 Remains Same, Total Order Increases):
    ETP Holder A submits a Replace Message to adjust quantity to 1100/
500.
    Example 7 Result: The order loses time priority because total 
quantity is increased, notwithstanding that display quantity remains 
the same.
    Example 8 (Tag 111 Remains Same, Total Order Decreases):
    ETP Holder A submits a Replace Message to adjust quantity to 900/
500.
    Example 8 Result: The order's time priority is maintained because 
display quantity remains the same and total quantity is decreased.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent 
with the provisions of Section 6(b) of the Act,\6\ in general, and 
Section 6(b)(5) of the Act,\7\ in particular, in that it is designed, 
among other things, to promote clarity, transparency and full 
disclosure, in so doing, to prevent fraudulent and manipulative acts 
and practices, 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 proposed rule change advances 
these objectives by making available to ETP Holders an order modifier 
that is currently in use elsewhere within the national market system 
and by clarifying order priority.\8\ Moreover, the proposed rule change 
is not discriminatory in that it applies equally to those ETP Holders 
that choose to utilize such functionality.

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

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Exchange Act.

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

    The Exchange has neither solicited nor received written comments on 
the proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    Because the foregoing proposed rule change does not: (i) 
Significantly affect the protection of investors or the public 
interest; (ii) impose any significant burden on competition; and (iii) 
become operative for 30 days from the date on which it was filed, or 
such shorter time as the Commission may designate, it has become 
effective pursuant to 19(b)(3)(A) of the Act \9\ and Rule 19b-4(f)(6) 
thereunder.\10\
---------------------------------------------------------------------------

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. 
NSX has satisfied 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.
