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.

Keep in mind, it should not really matter whether the DTC Server is setup or not. We understand it makes it "cleaner" for you, and that is fine. But in general, the ports are updated in each sub-instance, so those servers are not actually doing anything.

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

The above ports are the defaults. If you changed the ports in the main instance, then these settings should be set to the ports you set in the main instance.
