FIX MESSAGE 35=AC

MultilegOrderCancelReplace

MsgType (35) = ACMultilegOrdersAdded FIX.4.3

Definition

The MultilegOrderCancelReplace(35=AC) message (a.k.a. Multileg Order Modification Request) is used to modify a multileg order previously submitted using the NewOrderMultileg(35=AB) message. See OrderCancelReplaceRequest(35=G) for details concerning message usage.

Message structure 4133 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).
