In MQL5 you can have 1 position per symbol. If you buy 10 times, this still results into 1 position. You can only have more than 1 position if they belong to different symbols (markets).
I guess you are thinking that the block counts the number of deals who resulted into the current position. Visually multiple arrows are printed. But no, the block does not check this.
By the way I was never thinking about this. If I have to make this block again, I think I would make it this way, to detect how many deals there are in a position. Or I can make "Check trades count", but the last time I was working with those deals it was horrible, so I'm not sure how well such thing can be done 🙂
