Hi again Miro. I found a problem with the project options and I would like to ask for your help (again) if possible. 
I found the correct combinations for point format rules. The EA works perfect on each chart individually but it fails when combined. Let me explain. These are my initial rules:

As you can see I added gold and two indexes. Let's begin with any forex chart. This is what I get:

Just forget the closed pips. We can check that the open trade is correctly counted in pips. Now the same with gold:

Once again, it is correct. And now let's test it with DAX:

All is ok so far. The problem comes now when I put the EA in a fourth chart in order to calculate all open pips from the three previous charts simultaneously:

Where do those numbers come from? it doesn't even resemble a pip counter! Suddenly there are more than 15000 pips open right now!! :O. For some reason I don't understand, I cannot combine several charts at the same time.
Could you please give me any hint?
Once again, thank you very much in advance.
