Post From: DTC server sends unnecessary SECURITY_DEFINITION_RESPONSE messages

Definitely there is no functionality like this. When requesting market data, there is no security definition sent in response at all.

Maybe there is a connection to the data feed at the time market data is being requested and then there is automatically security definitions being sent for unrelated symbols because you have this option enabled:
Global Settings >> Sierra Chart Server Settings >> DTC Protocol Server >> Auto Send Security Definition for New Symbols. Disable that.
