Then pass the argument to the function, since it is provided. Although it is better to remove it, it is a tautology.
And not all orders in the loop will be recalculated.
The ticket with overwriting, working from the last order with a Martin.
and then how to remove the 'count' hides global declaration at line...
it is interesting to make it work as it should.
So far, the tester shows quite good results, and sometimes "insurmountable errors in the Expert Advisor".
Greetings.
Stumbled across a recording in this format:
I.e...here the conditional if statement has been replaced by a bool-type trade function instead of an expression. Do I understand correctly that such writing is equal to :
if(OrderSelect(ticket,SELECT_BY_TICKET))==true {OrderModify(ticket,OrderOpenPrice(), SL, TP,0};?
I've looked both in Help and in the tutorial - I haven't found such a format.
Can I use this way to directly write functions of a different type instead of an expression? And if so, what would be the algorithm?
I fixed it, put an argument, put it into global scope, now it generates a warning that this argument is already used as input in other functions

Just like thisif(OrderSelect(ticket,SELECT_BY_TICKET))==true {OrderModify(ticket,OrderOpenPrice(), SL, TP,0}; will not work. The condition must not be thrown out of brackets.
Butif(OrderSelect(ticket,SELECT_BY_TICKET)==true) {OrderModify(ticket,OrderOpenPrice(), SL, TP,0}; you can.

Please show me the corrected version, because without the code it is guessing.
Okay.
Sort of finished what I could. The description is done. The goal is to understand why it doesn't work the way I want it to.

Right? I just can't get it in there.
