Hi Roman,
Hope you are doing fine. Good, you solved your problem with the opposite directional signals.
Now, FSB Pro is quite a huge software if you get me. I use it so much and all the time I find something new and something I have missed.
Now I am doing big EAs(up to 20 conditions). I took me a long time to figure out how to structure the EAs, what logic groups to use.
It depends a lot on your trading methods and what is your logic in trading. But FSB Pro for sure is the more professional software(with more possibilities). And yes, it requires a goood machine.
