Hello, I have written about this previously and back then I was trying various ideas using two computers with two Sierra copies, two Sierra data connections and two instances of IB TWS as I remember.

Currently I would like to once again get this type of thing to work with a simpler set up. I have two instances of Sierra on one computer, I have one data connection and one IB TWS running. I would like to separate my trades so only long trades of the same symbol are traded in one instance and short trades of the same symbol are on the second instance.

Using Order Fill Calculated Trade Positions, I should be able to only see the long positions on one instance and the short position on the second instance even though they would cancel each other out in TWS and I would have no position. The problem I’m having is that on the second instance of Sierra under Global Settings >> Data/Trade Service Settings all I see is Service: DTC – Sub Instance [trading] greyed out in the top drop down menu and there is no place to set a different Instance Client ID number referenced from the instructions copied below. What do I need to do to change to a different Instance Client ID to make this work? Thanks for your help.

From the user guide: To have multiple copies of Sierra Chart connected to Interactive Brokers Trader Workstation (TWS), each copy of Sierra Chart needs to be set to a different Instance Client ID number, set with the Instance Client ID setting in the Service Settings section of the Global Settings >> Data/Trade Service Settings window.
