This message is used to request the suspension or release of a group of orders that match the criteria specified. This is equivalent to individual Order Cancel/Replace Request <35=G>s for each order with or without adding "S" to the ExecInst (18) values. It can also be used for mass order cancellation.
This message is acknowledged using an Order Mass Action Report <35=BZ>. The Order Mass Action Report <35=BZ> will contain the ClOrdID (11) that was specified on the request.
An Order Mass Action Request is assigned a ClOrdID (11) and is treated as a separate entity. The ClOrdID (11) assigned to the suspension or release request must be unique amongst the ClOrdID (11) assigned to regular orders, replacement orders, cancel requests, etc.
An immediate response to this message is required. It is recommended that an Execution Report <35=8> with ExecType (150) = "Pending Replace" (or "Pending Cancel" if used for mass cancellation) be sent unless the request can be immediately accepted.
MassActionType (1373) can be used to specify filtering criteria.
