FIX Message DontKnowTrade (MsgType=Q)
|MsgType||FIX Specification||First introduced|
|MsgType=Q||Trade messages - SingleGeneralOrderHandling||FIX.4.0|
The Don"t Know Trade (DK) message notifies a trading partner that an electronically received execution has been rejected. This message can be thought of as an execution reject message.
This message has special utility when dealing with one-way execution reporting. If the initial Order Acknowledgment message (Execution Report with LastQty=0 and OrdStatus=New) does not match an existing order this message can be used to notify the broker of a potential problem order.
Note that the decision to DK an execution lies with the institution. Some of the mismatches listed in the DKReason field may be acceptable and will not require a DK messages to be generated.
