During periods of inactivity, a third-party FIX acceptor should generate a heartbeat message at regular time intervals. The Heartbeat (0) message is used by FIX Gateway to monitor the status of the communication link. You specify the heartbeat interval timer in Tag 108 (HeartBtInt) of the Logon (A).
The third-party FIX acceptor should reset the heartbeat interval timer after every transmitted message (not just heartbeats). When either party stops receiving data for the specified heartbeat interval, it should send a Test Request (1) message to verify the connection. The counterparty should send a Heartbeat (0) message in response. If a party receives no Heartbeat (0) message in a reasonable amount of time, the connection should be considered lost.
