Do you want to set a limit for the maximum number of trades open at the same time?
What if you have two open orders (one long and one short) and a new signal apears? Should the EA open another order? (and have a total of 3 open orders)

By the way, I like your EA. Have you been using it? On which pair did you get the best results?

I gtg now but I will modify your EA tomorrow.
Bye.
