Definition
The Allocation Instruction message provides the ability to specify how an order or set of orders should be subdivided amongst one or more accounts. In versions of FIX prior to version 4.4, this same message was known as the Allocation message. Note in versions of FIX prior to version 4.4, the allocation message was also used to communicate fee and expense details from the Sellside to the Buyside. This role has now been removed from the Allocation Instruction and is now performed by the new (to version 4.4) Allocation Report and Confirmation messages.,The Allocation Report message should be used for the Sell-side Initiated Allocation role as defined in previous versions of the protocol.
Message structure 347 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.
