Thanks, GeorgeQuote from GeorgeClueney:
Are you referring to multi-threading and the number of threads in analysis?
Standard Edition 2 threads, Professional Edition 32 threads

Additional info in their manual about efficient use of multi-threading

Or do you mean multiple streams of data vendors?
Anyway you can open multiple AmiBroker instances (each one connected to a different source) and multiple Analysis windows and multiple charts. And of course if you feel there is a vendor missing (or anything else) then you have the choice to add your own by using the free AmiBroker C/C++ SDK. But there is another commercial .NET SDK for AmiBroker available if you prefer that one.
Otherwise if you have any technical questions then better ask their support as I'm not affiliated with them but am just a user.
I'm not talking about multi-threading or multiple vendors, and I probably didn't express myself correctly. I suspect neither AmiBroker nor any other platform vendor is set up to provide what I'm looking for. Thanks for the info.
