Post From: Sub Instances Connect To The Wrong

The item you need to change is "Global Settings >> Sierra Chart Server Settings >> DTC Protocol Server". Make sure this is set "No" for any instance you do not want to be a DTC server. This would be ALL your sub-instances. The only instance that should have this set to "Yes" is your main instance.

That is "the problem"
When I change "Yes"--->"No" in all sub-instances (6) they will stay like that during trading session; they will go back to "Yes" when I terminate sub-instances and start them again
...
Also, check the settings in each sub-instance for "Global Settings >> Data/Trade Service Settings >> Main Settings". The items in there should be the following:
- Current Selected Service: DTC - Sub Instance (read-only)
- Server Address: 127.0.0.1
- Server Port: 11099
- Historical Data Server Port: 11098

This is all very much the same in my case
In my case instead of
Current Selected Service: DTC - Sub Instance (read-only)
I have
Current Selected Service: DTC - Sub Instance [trading]
...
...
All this is just my ability to exercise that possibility to have 1 instance as server and 6 sub-instances
I have no conflict of any kind (that I noticed)


Thank you very much for your late Friday effort
