FIX 4.0 : Logout <5> message

Structure | Sample Message | Related Messages


The Logout <5> message is to used to initiate or confirm the termination of a FIX session. Disconnection without the exchange of Logout <5> messages should be interpreted as an abnormal condition.

Before actually closing the session, the logout initiator should wait for the opposite side to respond with a confirming Logout <5> message. This gives the remote end a chance to perform any Gap Fill operations that may be necessary. The session may be terminated if the remote side does not respond in an appropriate timeframe.

The logout initiator should not send any messages after the logout.
