IB Controller 1.3.8 with two simultaneous accounts

I would like to launch my automated trading system and I need to work with two Interactive Brokers accounts, one main and one linked. Is it possible to do this simultaneously with IB Controller 1.3.8?

Only if you run from separate Windows accounts (you need to login to Windows twice with separate accounts and run separate instances of TWS and configure them to use different port).

An alternative is to use Family & Friends account.

I trust your answer @Tomasz

A follow up question, what if I use two Analysis windows and set the account value for the PlaceOrder method, won't that not work?

Thank you.
