How to calculate the sum of all open lots?

[Acc]

Good afternoon! Dear Administrators, I am developing a grid expert Advisor, and at some point, he should calculate the sum of all open lots. To open the opposite position in a double size (for example). I was faced with the problem of how to make a loop? And return the resulting value to a variable? Please tell me how to solve this problem? Thanks in advance!

Thank you very much! It works. I have another question, why the EA is no longer working after exporting? I opened the code in MetaEditor when compiling writes: "template parameter ambiguous, could be 'double' or 'int'." This is for all previous projects AAAaaaaa!!!

For some reason MetaEditor swears to the execution blocks: "check last winner\loser type". What to do now?

There was a bug in one function, is it ok now?

No, still does not work. I tried to make a new project, it works, until you don't add a blocks: "check last winner\loser type".
