Storing the risk taken on a pair's individual currencies as a variable?

[gaberen]

I'm currently working on a multi-symbol MT5 EA to help me backtest my algorithms. I want to store the risk of each currency from the fx pairs I trade to make sure that I don't risk too much on correlated symbols.

Here is a snippet of my project:

I'm currently trying to use Global Variables but it hasn't been working like I want it to. The way I have it right now, it only stores the risks of the 2 currencies from the pair selected in the strategy tester settings (see Pictures below). I want it to store the risks of all the currencies that the EA is trading.

I'm not really sure if Global Variables are the way to do it, does anyone have any better ideas?

Thank you in advance!

This is definitely not my field of expertise. I hope jstap can give you a hand.

I have managed to do it by using a CHashMap as a dictionary and also by using the function CurrentSymbol()
I can't explain it well but here's what I have for my code

Next I need to find out how to cut off the next block from running (disabling a trade from being placed) if the risk on a symbol is too high, I've tried using " return; " but it doesn't seem to be working as I want it to, but I'll go ask that on another thread if I really can't figure that out.

EDIT: Turns out I can use ~next~ and ~inext~ to allow and disallow the next block from running
