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
| Tag | Name | Type | Required | Description |
|---|---|---|---|---|
| 7 | BeginSeqNo | SeqNum | yes | Message sequence number of the first message in range to be resent. |
| 16 | EndSeqNo | SeqNum | yes | Message 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.
