2 (Resend request)

The 2 (Resend request) message is sent by the receiving application to initiate the retransmission of messages.

This function is used:

  • If a sequence number gap is detected
  • If the receiving application lost a message
  • As a function of the initialization process

The 2 (Resend request) message can be used to request:

  • A single message
  • A range of messages
  • All messages subsequent to a particular message

TagNameTypeRequiredDescription
7BeginSeqNoSeqNumyesMessage sequence number of the first message in range to be resent.
16EndSeqNoSeqNumyesMessage sequence number of the last message in range to be resent.

If the request is for a single message, 7 BeginSeqNo = 16 EndSeqNo.
If the request is for all messages subsequent to a particular message, 16 EndSeqNo = 0 (representing infinity).

For a sample message and other details, see FIX 4.4 : Resend Request <2> message in the FIX 4.4 documentation.
