The International Securities Exchange, LLC (ISE) has filed with the Securities and Exchange Commission a proposal to amend ISE Rule 715 (Types of Orders) to provide for the submission of a new type of order, “attributable orders.” Attributable orders are market or limit orders that allow an ISE member firm to voluntarily display its Firm ID (a unique 3-5 character identification code assigned by the ISE to each member firm) on the orders.

ISE has proposed these orders in response to requests by ISE members that believe that enhanced executions may be obtained if a Firm ID is allowed on orders (on a voluntary basis). ISE will issue a Regulatory Information Circular specifying the systems and the options classes for which the attributable order type will be available.
