Detailed logic description

Main flow

Successful connection without any issues.

...

In case end user connects to Handler_Session, then Driven_Session initiates connection to the venue. All business messages from Driven_Session, will be routed into the Handler_Session.

Exceptional flows

Logout comes from Handler_Session

In case end user disconnected from Handler_Session for any reason, the Driven_Session will be disconnected automatically.
Case is also valid for unexpected break of the Handler_Session.

Logout comes from Driven_Session

In case Driven_Session became disconnected, FIXEdge will try to reconnect Driven_Session and in case failure end user will be disconnected from Handler_Session automatically.

Endpoint for Driven_session unavailable

In case end user connects to Handler_Session, the Driven_Session initiates connection to the venue, but was not able to establish connection, Handler_Session will be disconnected automatically.
Case is also valid for unexpected break of the Driven_Session.

Schedules

It is possible to configure Handler_Session to listen by schedule and be restarted after disconnect only in the configured interval.
