Session Termination

The Logout message requests or indicates the termination of a FIX session. The logout initiator should wait for a response and/or confirmation to the logout condition. This will permit the counterparty to gently close its connection and honor a potential message gap-fill.

If the T4 FIX API server initiates a Logout, an issuing physical disconnection will follow. When possible, the T4 FIX API will provide information on the nature or cause of the termination. If the client sends a Logout message, no more messages should be sent by the client.

Under normal operating conditions, the client requests a logout and the T4 FIX API server honors the request. A physical disconnection without an exchange of Logout messages is considered an abnormal condition.

Failed Authentication

To start a new FIX session, the T4 FIX API will need to reach successful authentication of the client's Logon message. To provide as much information as possible, a failed authentication is responded (by the T4 FIX API) with a Logout message.

A new FIX session (with sequence numbers reset to 1) will be required after the receipt of a Logout message and its subsequent physical disconnection.
