Session TerminationThe 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 gap-fill operation that may be necessary.
If the T4 FIX API server initiates a Logout, an issuing physical disconnection will follow. When possible, the T4 FIX API will provide information to the client on the nature or cause of the FIX session termination. If the client sends a Logout message, no more messages should sent by the client.
Under normal operating conditions, clients request a logout and the T4 FIX API server honors their request. A physical disconnection without an exchange of Logout messages is considered an abnormal condition.
Failed AuthenticationTo start the new FIX session, the T4 FIX API will need to achieve sucessful authentication of the client's
Logon message. To provide as much information as possible, a failed authentication is responded with a Logout message by the T4 FIX API.
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.
