Effective close of business, Thursday, August 21st for start of day, Friday August 22nd the American Stock Exchange (Amex) will implement a new outbound message type in the Equity Intra-Day Comparison System (IDCE) MQ Service.
This enhancement as earlier reported with a July 28th notice will provide Specialist Clearing Firms with the ability to receive notification of Specialist Action Without Order (AWO) transactions.
The new IDCE MQ outbound message will have a Record ID of "H" in position 6, a Trade Status Indicator of "U" in position 127, and a Branch Code of "ZYX" in positions 202 to 204. The prior July 28th notice had incorrectly listed "ZXY" as the Branch Code.
