Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”), and Rule 19b-4 thereunder, notice is hereby given that on January 14, 2011, BATS Y-Exchange, Inc. (the “Exchange” or “BYX”) filed with the Securities and Exchange Commission (“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 is filing with the Commission a proposal to amend BYX Rules 11.9, 11.13 and 11.19 to make certain changes consistent with the upcoming implementation of amendments to Regulation SHO.

The text of the proposed rule change is available at the Exchange's Web site at http://www.batstrading.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 parts of such statements.

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

1. Purpose

On February 26, 2010, the Commission adopted amendments to Regulation SHO under the Act in the form of Rule 201, pursuant to which, among other things, short sale orders in covered securities generally cannot be executed or displayed by a trading center such as BYX at a price that is at or below the current national best bid (“NBB”) when a short sale circuit breaker is in effect for the covered security (the “short sale price test restriction”). In anticipation of the upcoming February 28, 2011 compliance date for Rule 201, the Exchange is proposing to amend certain BYX rules to describe the manner in which the System will handle short sell orders when a short sale price test restriction is triggered under Rule 201 of Regulation SHO. These changes include establishing a definition for “short sale price sliding,” which is a new form of price sliding the Exchange proposes to offer when the amendments to Regulation SHO become operative, modifying certain BYX rules regarding order execution and routing when a short sale price test restriction is in effect, and modifying BYX rules related to order marking requirements. Additionally, the Exchange proposes to modify the definition of the current “displayed price sliding process” offered by BYX.

In order to comply with the short sale price test restriction of Regulation SHO, as amended, the Exchange proposes to offer short sale price sliding, which will be defined in BYX Rule 11.9(g). As a default, the Exchange will subject a User's orders to the short sale price sliding unless they affirmatively choose to opt-out of the process. As proposed, when a User opts out of the price sliding process, any short sale order that could not be executed or displayed due to a short sale price test restriction would be rejected or cancelled by the Exchange upon entry or while resting on the order book, respectively. When a User's order is subject to the price sliding process, as proposed, orders subject to short sale price sliding that, at the time of entry, could not be executed or displayed due to a short sale price test restriction will be repriced by the System at one minimum price variation above the current NBB to comply with Rule 201(b)(1)(i). An order subject to short sale price sliding will not be readjusted downward even if it could be displayed at a lower price without violation of Rule 201 of Regulation SHO. In the event the NBB changes such that the price of a non-displayed order subject to short sale price sliding would lock or cross the NBB, the order will receive a new timestamp, and will be repriced by the System at one minimum price variation above the current NBB, again in compliance with Rule 201(b)(1)(i).

As proposed, neither orders marked “short exempt” nor orders displayed by the System at a price above the then current NBB at the time of initial display when a short sale price test restriction is in effect for a covered security will be subject to short sale price sliding. Certain displayed short sale orders will not be repriced by the System after entry because under Rule 201(b)(1)(iii)(A) a trading center's policies and procedures must be reasonably designed to permit the execution of short sale orders of covered securities that were displayed at a price above the current NBB at the time of initial display. “Short exempt” orders will not be repriced by the System, but instead, the Exchange will execute, display and/or route such orders without regard to the NBB or any short sale price test restriction in effect under Regulation SHO, as described below.

The Exchange currently offers a process called “displayed price sliding process,” as defined in current Rule 11.9(c)(4), which re-prices and/or displays orders at permissible prices when such orders would lock or cross Protected Quotations in a manner inconsistent with Rule 610(d) of Regulation NMS. The Exchange proposes to rename the “displayed price sliding process” as “NMS price sliding,” to be included in new paragraph (g) of Rule 11.9, and to define the “price sliding process” as inclusive of both NMS price sliding and short sale price sliding. Also, consistent with the changes described above, the Exchange proposes to replace the term “displayed price sliding process” throughout its trading rules with the term “price sliding process.” As is true for displayed price sliding today and short sale price sliding as proposed, if a User chooses to opt-out of the price sliding process, the order will not be subject to NMS price sliding, and thus, the Exchange will cancel back their orders when display or execution of such orders contradict the provisions of Regulation NMS.

The Exchange also proposes a substantive change to NMS price sliding (today known as the displayed price sliding process). Under current System behavior, the Exchange cancels all non-displayed orders when the national best bid or offer (“NBBO”) changes such that the non-displayed order would cross a Protected Quotation, regardless of whether the order is subject to the displayed price sliding process. Under the proposed amendment, instead of cancelling such orders, unless a User has opted out of the price sliding process, the Exchange proposes to allow a resting non-displayed order to receive a new timestamp and be repriced at the locking price in the event that the NBBO changes such that the order would cross a Protected Quotation.

The Exchange also proposes to amend its Rule 11.13 to make clear that it will execute, display and route an order consistent with Rule 201 of Regulation SHO, and that if it cannot do so, orders will be cancelled back to the applicable Exchange User. In addition, the Exchange proposes to make clear that it will not route orders away from the Exchange that are marked “short” if a short sale price test restriction is in effect. Instead, such orders, if immediate-or-cancel (“IOC”) or market orders, will be cancelled, and if limit orders, will be posted to the BATS Book, subject to the price sliding process.

Finally, current Rule 11.19 requires Exchange Users to identify short sale orders as “short” when entered into the Exchange's System. The Exchange proposes to add the term “short exempt” to Rule 11.19 because pursuant to amended Rule 200(g) of Regulation SHO, a broker-dealer can mark a short sale order as either “short” or “short exempt.” The Exchange also proposes to make clear in Rule 11.19 that if an order it received is marked “short exempt,” the Exchange will execute, display and/or route the order without regard to the NBB or any short sale price test restriction in effect under Regulation SHO. The Exchange also proposes to make clear, as it does in Rule 11.9(d)(1) with respect to intermarket sweep orders, that it relies on a Member's marking of an order, in this case the “short exempt” marking, when handling such order. Accordingly, proposed Rule 11.19 states that it is the entering Member's responsibility, not the Exchange's responsibility, to comply with the requirements of Regulation SHO relating to marking of orders as “short exempt.”

2. Statutory Basis

The Exchange believes that its proposal is consistent with the requirements of the Act and the rules and regulations thereunder that are applicable to a national securities exchange, and, in particular, with the requirements of Section 6(b) of the Act. In particular, the proposed change is consistent with Section 6(b)(5) of the Act, because it would promote just and equitable principles of trade, and, in general, protect investors and the public interest. The Exchange believes that the proposed changes will provide clarity on the short sale order handling procedures employed by the Exchange and certain obligations of Members when sending short sale orders to the Exchange consistent with Regulation SHO, as amended. The Exchange also believes that the proposed short sale price sliding functionality and amendments to the existing displayed price sliding process will assist Users in executing or displaying their orders consistent with Regulation SHO and Regulation NMS, especially under fast moving conditions where the NBBO is quickly updating. In addition, as is currently the case, the amended price sliding process is optional to Users. Specifically, Users can choose to opt-out of the price sliding process, and if they choose to do so, the Exchange will cancel back their orders when such orders contradict the provisions of Regulation SHO or Regulation NMS.

(B) Self-Regulatory Organization's Statement on Burden on Competition

The Exchange does not believe that the proposed rule change imposes any burden on competition.

(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.
