IBC controller disconects


I am using IBconctroller to place orders to Interactive broker.

I am using Amazon windows server to host all applications( Amibroker, IB COnroller and TWS)

I am having two separate logins for Interactive broker and thats why I have installed two TWS in same server but in different user profile.

Problem is when I activate one IBC on server login it disconects another IBC in other server login.

Is there a way to resolve it ?


IBC uses IP address ( - local host and port number, so it does NOT matter that you used "different windows profile". It will connect ANYWAY because it does not care about Windows.

To connect to different instances you have to use different port.
