Cancel Request is Acknowledged

Usage

When the Client sends an OrderCancelRequest to Moment, Moment will immediately respond with an ExecutionReport with an ExecType of "Pending Cancel" (150=6) to indicate that Moment has received the cancel request. Moment will subsequently send the Client one of the following:

1. An OrderCancelReject (35=9) indicating that Moment has rejected OrderCancelRequest.
2. An ExecutionReport (35=8) indicating that the order has been successfully canceled and the Client should expect no further updates on the order.
3. An ExecutionReport (35=8) indicating that an additional update has occurred to the order before the order could be canceled. While uncommon, this could occur if there is an in-flight fill for the order. If the order is still open after the new update, Moment will attempt to cancel the remainder of the order.

Unlike all other Execution Report messages, the cancel acknowledgement message indicates an update to the Cancel Request's state, not the Order's state. As a result, the ClOrdID in the cancel acknowledgement refers to the ClOrdID of the Cancel Request, and all fields referring to the Order's attributes are omitted. The cancel acknowledgement does not represent a change in the Order's state. Moment will subsequently send an update to the Order's state if the Order is successfully canceled.
