Thanks ... I'll keep that in mind)))

to Reshetov^ Like this: int start() { Comment("Open positions: ", OrdersTotal()); string smb=Symbol(); int tf=Period(); gsID=smb+IsDemo()+IsTesting()+IsOptimization()+"."+Magic; inf=""; INF(TTS(TimeCurrent()), true); main(Magic, smb, tf); Comment(inf); and where and how will the number be displayed?

[Юсуфходжа]

Why is my "comment" and "edit" function broken ? There are no top options - the top is completely blank - you can't add pictures, for example. What has this got to do with it?

There is a magic combination: Ctrl+Alt+M and a useful key "Enter", so as not to spoil the vision of interlocutors. Since eyesight is more precious, I can't answer anything specific on your code-washing.

Can you tell me how to work with ArrayMaximum in the EA? In the indicator it works, I marked arrays and buffers, but in the EA it is not clear.

You need to prepare the array first. Try the script given in the MetaEditor's help:

//+------------------------------------------------------------------+
//| script program start function                                    |
//+------------------------------------------------------------------+
int start(){
  double num_array[15]={4,1,6,3,9,4,1,6,3,9,4,1,6,3,9};
  int    maxValueIdx=ArrayMaximum(num_array);
  Alert("Max value = ", num_array[maxValueIdx]);
  
  return(0);
}
//+------------------------------------------------------------------+

In my indicator it looks like this:

sm[i]=...........;

double IndexMaxValue=ArrayMaximum(sm,n,shift);

I don't know how to attach it to your script, how to do it in the Expert Advisor?

I can output sm[i] via iCustom, but how can I put the iCustom variable into ArrayMaximum?

[Владимир Тезис]

Alexandr24:

but how can iCustom variable be put into ArrayMaximum it's not an array?

I didn't cite the documentation for nothing. There is such a thing as description of parameters to be passed to function inputs. If it is written there that the parameter must be an array name, shoving another function (iCustom() in its place will do us no good. It means that before calling ArrayMaximum() we should declare array, then fill this array with values and only after that call ArrayMaximum().

I tried to put the code of the indicator in an EA, but nothing works, the thing is that an indicator needs to indicate buffers and I haven't seen it in EAs, that's why an indicator works and the same code doesn't work in an EA. I have an array filled with cycle sm[i] and indicator sees it but EA with the same code does not. Maybe, the arrays in EAs should be declared differently than in indicators?
