Post From: Automated Trading System - Custom Study - Two Chartbooks Running Simultaneously

I utilize a custom study as a component of an automated trading system ("ATS"). I use the ATS to trade one instrument - MNQ - in a chartbook with a 5 minute chart and a separate chartbook with a 7 minute chart. I run both chartbooks simultaneously and tied to the same account. Note: In SIM, I use the Trade Window to assign different SIM accounts to each chartbook: SIM1, SIM2.


However, when I run both chartbooks simultaneously, the ATS doesn't operate properly as entries and exits do not follow the logic coded into the ATS. When I run only one chartbook at a time, the ATS operates properly.


In order to run both chartbooks simultaneously, is a possible solution to have a second Sierra Chart installation but downloaded onto the same computer and tied to the same account? Is there a better solution you can propose?


Thank you in advance.
