Please, don't request help for ChatGPT (or other A.I.) generated code. It generates horrible code, mixing MQL4 and MQL5. Please use the Freelance section for such requests — https://www.mql5.com/en/job

this is not the chatgpt code but it is part of the code of my robot created by a developer here on mql5 but currently it is no longer reachable on telephone

then I want the robot to add a single pending position, this is fine in the strategy tester but on a demo account it opens more than two pending positions.

If you are not a coder then you will probably not be able to understand any advice given to you, nor are we going to code it for you.

You have only provided a small part of the code and it may not even be relevant within the context of the entire program.

So, I suggest you hire another coder to make the necessary changes for you.
