Making sure only one position open per currency pair: Coding help

Hello fellow forex traders,

I have a system that I am testing out and realized that the way it is programmed, it is probably going to open a new position after several ( up to 10) 4 hr candles. I've been looking around and couldn't find any code to implement that would assure that I only have on position open (either long or short) per currency pair. It's a moving average and ADX system.

I have to say that I did not code this one, I used an automatic system online that I just wanted to try. I'm not sure the code is in there to have just one position open.

If you guys could take a look at this and tell me if it is going to open a bunch of lots that would be great. I'm already indebted!
