Message Notes

A Test Request (1) message is used to force the counterparty to respond with a Heartbeat (0) message to validate the state of the connection between a FIX client and the TT FIX Adapter.

When either party stops receiving data for the specified heartbeat interval, it should send a Test Request (1) message. The counterparty should send a Heartbeat (0) message in response. If a party does not receive a Heartbeat (0) message in a reasonable amount of time, the connection should be considered lost.
