Re: Intermittent Heartbeats

27 May 2005 11:26AM ET To add on to the points already mentioned, Heartbeats can also be sent in response to a Test Request message.
A counterparty can issue a Test Request to verify connection status. Its proper FIX to respond to a Test Request, with a HeartBeat message. This HB message will reference a Test Request ID(Tag 112).
This can occur within the set HeartBeat interval and may be initially viewed as a randomly sent message.
