EA works on one broker, doesn't on another

Hello, included an indicator written with the help of a source i am not going to mention here because people might see it as commercial intentions.
I wrote this indicator to do the following:

1. Ontrade close -> check how closed -> take profit
2. If take profit -> delete current open pending orders

So once my current market order hits its TP, all remaining pending orders should close.
The code is working because i have tested this on multiple brokers. One of them is FXCM demo and it works fine.

However, on my live Pepperstone account this does not work as intended. The " ontrade close -> check how closed -> take profit -> if take profit " works fine but it does NOT delete current open pending orders here for some reason.

Why is is that this indicator works on FXCM but not on Pepperstone? I contacted Pepperstone and they had no clue, suggested me to contact the author of the EA. He claims its ECN ready so if one of you knows more... last but not least i am NOT receiving any error messages whatsoever in my journal. Help is much appreciated. Thanks.

I now know the cause. It is not labeling the comments correctly. While FXCM shows [tp] and [sl] in its comment section, pepperstone does not.
Is there a seperate EA / alternative available to label closed trades in the comment section of MT4?

Only the broker can modify the comment. Can you change the logic to check if the order closed in profit instead?

Yeah, i am trying some workaround at the moment. Trying to implement a trigger after "x" amount of pips instead of a TP close. Lets see if it will work, cheers.

And ofcourse this doesnt freaking work on Pepperstone yet again, but works on other brokers. Pepperstone removes the pending orders right away, even when the TP is 200 pips away from being hit. 1pip distance is the trigger, not 200pips.

What is this shit with all EA logic failing on Pepperstone. I did not had complaints about them yet but when it comes to EA its an absolute mess. Been experimenting, researching for 3 days already and with no results at all.
