{{Quickfixn}} How Should A Session Be Closed

[Mike Gatny]

Hi Ian,

Could you provide a little background on what your use case is for stopping
particular Sessions manually?
It is more typical to let the Initiator manage stopping and starting
Sessions for you, e.g. using the StartTime/EndTime SessionSettings, or by
calling Stop() on the Initiator itself to stop all Sessions.
Depending on your use case the Initiaiator's AddSession/RemoveSession
methods might be useful to you.  See:
