MQL4 Pending Order Help

Hello Coders,

I am working on an EA that places two (2) pending orders under certain market conditions. One Buy Stop above current price and one Sell Stop below current price. With that said, I am trying to write some code that DELETES the opposing order, once one is triggered. I know it's possible - probably something along the lines of OrderSelect function. I am just new to the logic of coding.

I sincerely appreciate any time that anyone will take to assist with this.

Regards,

Check if you have only 1 pending ... If so, that should mean the other one was triggered ... so delete the remaining one.

That makes sense and all, and I did arrive to this conclusion. But I don't know how to write this kind of code, and wouldn't know what to search for on Google. Thus my thread here. However, I will give it some more thought. Thank for your time!!
