17 CFR § 240.11a-1 - Regulation of floor trading.
(a) No member of a national securities exchange, while on the floor of such exchange, shall initiate, directly or indirectly, any transaction in any security admitted to trading on such exchange, for any account in which such member has an interest, or for any such account with respect to which such member has discretion as to the time of execution, the choice of security to be bought or sold, the total amount of any security to be bought or sold, or whether any such transaction shall be one of purchase or sale.
(1) Any transaction by a registered specialist in a security in which he is so registered on such exchange;
(2) Any transaction for the account of an odd-lot dealer in a security in which he is so registered on such exchange;
(4) Any bona fide arbitrage transaction;
(5) Any transaction made with the prior approval of a floor official of such exchange to permit such member to contribute to the maintenance of a fair and orderly market in such security, or any purchase or sale to reverse any such transaction;
(6) Any transaction to offset a transaction made in error; or
(7) Any transaction effected in conformity with a plan designed to eliminate floor trading activities which are not beneficial to the market and which plan has been adopted by an exchange and declared effective by the Commission. For the purpose of this rule, a plan filed with the Commission by a national securities exchange shall not become effective unless the Commission, having due regard for the maintenance of fair and orderly markets, for the public interest, and for the protection of investors, declares the plan to be effective.
(c) For the purpose of this rule the term “on the floor of such exchange” shall include the trading floor; the rooms, lobbies, and other premises immediately adjacent thereto for use of members generally; other rooms, lobbies and premises made available primarily for use by members generally; and the telephone and other facilities in any such place.
The Commission finding that the floor trading plan of the New York Stock Exchange filed on May 25, 1964 is designed to eliminate floor trading activities not beneficial to the market hereby declares such plan effective August 3, 1964 subject to suspension or termination on sixty days written notice from the Commission, 29 FR 7381, June 6, 1964.
The Securities and Exchange Commission acting pursuant to the Securities Exchange Act of 1934, particularly sections 11(a) and 23(a) thereof, and Rule 11a-1 (17 CFR 240.11a-1) under the Act, deeming it necessary for the exercise of the functions vested in it, and having due regard for the maintenance of fair and orderly markets, for the public interest, and for the protection of investors, hereby declares the Floor Trading Plan of the American Stock Exchange, as amended by amendments filed on May 11, 1967, effective January 31, 1968. If at any time it appears to the Commission to be necessary or appropriate in the public interest, for the protection of investors, or for the maintenance of fair and orderly markets, or that floor trading activities which are not beneficial to the market have not been eliminated by the Floor Trading Plan of the American Stock Exchange, the Commission may suspend or terminate the effectiveness of the plan by sending at least 60 days written notice to the American Stock Exchange. The American Stock Exchange shall have the opportunity to submit any written data, facts, arguments, or modifications in its plan within such 60-day period in such form as the Commission deems appropriate under the circumstances. The Commission has been informed that all persons subject to the Floor Trading Plan of the American Stock Exchange, as amended, have had actual notice thereof, and the Commission finds that notice and procedure pursuant to section 4 of the Administrative Procedure Act (5 U.S.C. section 553) are impracticable and unnecessary and that such Plan, as amended, may be, and is hereby, declared effective on January 31, 1968.
