AFAIK, you can't start several times from the same terminal.exe.
Anyway it's 32 running instances of terminal.exe
I installed 40 terminals, but only 32 started.
Then I created another user on the Win2012 server and started another 32 terminals.
It looks that if user can't see list of all tasks, you can start 32 terminals per user.
At the end of the experiment, I had 2 users logged in with total of 64 terminals running. Each terminal had only one pair in Market watch and one chart open without indicators or EA's and CPU was on 100%
It looks that you can start more than 32 terminals per PC, but that doesn't look very usable.
How do I test the influence if I use multiple strategies at the same account?
So 1 account, 3 chats: Grid trader, scalper en another EA, or doesn't I have to test this because the EA's are winners separate, so they don't affect the other?
