Definition
The OrderMassActionReport(BZ) message is used to acknowledge an OrderMassActionRequest(35=CA) message. Each affected order that is suspended, released or canceled is responded to with a separate ExecutionReport(35=8) message for each order.
Message structure 2639 distinct fields
Source order, including nested components and groups. Group counts precede the repeated entries. “Required here” is relative to the enclosing component or group, not unconditional in the message. A dash means not marked required; conditional requirements remain in the source notes. This is a reference, not a counterparty-specific validator.
Nested fields load when needed. Open the full static layout (also works without JavaScript).
