The ApplicationSequenceControl is used for application sequencing and recovery. Consisting of ApplSeqNum <1181> (1181), ApplID <1180> (1180), ApplLastSeqNum <1350> (1350), and ApplResendFlag <1352> (1352), FIX application messages that carries this component block will be able to use application level sequencing. ApplID <1180>, ApplSeqNum <1181> and ApplLastSeqNum <1350> fields identify the application id, application sequence number and the previous application sequence number (in case of intentional gaps) on each application message that carries this block.
The ApplResendFlag <1352> (1352) is used to indicate that messages are being retransmitted as a result of an Application Message Request.
See Application Sequencing Message section for further details on usage and restrictions.
