###### Securities and Exchange Commission

          - [Release No. 34-64214; File No. SR-BYX-2011-007] 

      ( print page 20430)    
                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on April 1, 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 extend a pilot program related to Rule 11.18, entitled “Trading Halts Due to Extraordinary Market Volatility.” 

                    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 

The purpose of this filing is to extend the effectiveness of the Exchange's rule related to individual stock circuit breakers, which is contained in Rule 11.18(d) and Interpretation and Policy .05 to Rule 11.18. The rule, explained in further detail below, was approved to operate under a pilot program set to expire on April 11, 2011. The Exchange proposes to extend the pilot program to the earlier of August 11, 2011 or the date on which a limit up/limit down mechanism to address extraordinary market volatility, if adopted, applies. 

                    On October 4, 2010, the Exchange filed an immediately effective filing to adopt various rule changes to bring BYX Rules up to date with the changes that had been made to the rules of BATS Exchange, Inc., the Exchange's affiliate, while BYX's Form 1 Application to register as a national securities exchange was pending approval. Such changes included changes to the Exchange's Rule 11.18, on a pilot basis, to provide for uniform market-wide trading pause standards for individual securities in the S&P 500® Index, the Russell 1000® Index and specified Exchange Traded Products that experience rapid price movement.[3]                                          The pilot program relating trading pause standards was then extended to April 11, 2011.[4]                                          The Exchange believes the benefits to market participants from the individual stock trading pause rule should be continued on a pilot basis.                 

####                     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.[5]                                          In particular, the proposal is consistent with Section 6(b)(5) of the Act,[6]                                          because it would promote just and equitable principles of trade, remove impediments to, and perfect the mechanism of, a free and open market and a national market system. The proposed rule change is also consistent with Section 11A(a)(1) of the Act [7]                                          in that it seeks to assure fair competition among brokers and dealers and among exchange markets. The Exchange believes that the pilot program promotes just and equitable principles of trade in that it promotes transparency and uniformity across markets concerning decisions to pause trading in a security when there are significant price movements.                 

### (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. 

## 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 if consistent with the protection of investors and the public interest, it has become effective pursuant to Section 19(b)(3)(A) of the Act [8]                                          and Rule 19b-4(f)(6) thereunder.[9] 

                    A proposed rule change filed under Rule 19b-4(f)(6) normally may not become operative prior to 30 days after the date of filing.[10]                                          However, Rule 19b-4(f)(6) [11]                                          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.                 

                    The Commission has considered the Exchange's request to waive the 30-day                           ( print page 20431)                        operative delay. 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 pilot program to continue uninterrupted, thereby avoiding the investor confusion that could result from a temporary interruption in the pilot program.[12]                                          For this reason, the Commission designates the proposed rule change to be operative upon filing.                 

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
