What is the question and why the screenshot?

Press "All" button to see all objects created programmatically.

Help in MetaTrader 5 → Work with Charts → Manage Chart → Lists of superimposed objects:

List of objects

The following commands are available in the object list window:

  • Show - move the chart to the selected object;
  • Properties - go to edit properties of the selected object;
  • Delete - deletes the selected object;
  • All - the "hidden" (OBJPROP_HIDDEN) property can be set for any object in MQL5. Such objects are displayed in a chart but they are not shown in the list of objects by default. If you click "All", hidden objects will be displayed in the list.

The Ctrl+A hotkey can be used to select all objects in the window.

 

You know I can't get these English words to make sense '}' - not all control paths return a value order.mq5 83 90

Please explain, what is it, in the sense of a writeable function? Thank you.

Here, maybe this will make it clearer to you and me what it is,

 bool OrderSelectt ( int i) { string stringg= "" ; stringg=PositionGetSymbol(i);
                           if (stringg!= "")return true ;
                           if (stringg== "")
                           if(0!= OrderGetTicket(i)) return true ; else return false;    }
Who controls or does not control what...

Example

int func(int param)
  {
   if(param==5)
     {
... какой-то код
// в конце блока не стоит return
     }
   else
     {
... какой-то код
      return(0);
     }
// нет общего ретурна
  }
So, in the above example, there is return for only one case where param != 5. For all other branches, return is not defined. This is what "not all control paths return value" means
 

THANK YOU!

Yeah, but I still can't figure out how to build a condition that would give a falser if the string is " " and if OrderGetTicket(i) also gives zero. I think I have returns where I need them!

 

Your writing is correct. This seems to be a fault of ours. Please write a request to the service-desk.

In the meantime, reformulate the function as follows

bool OrderSelectt(int i)
  {
   string stringg=PositionGetSymbol(i);
   if(stringg!="")
      return(true);
   else
     {
      if(0!=OrderGetTicket(i))
         return(true);
      else
         return(false);
     }
  }
 
I delete an indicator window with a code like this - it doesn't draw anything...
...
   int limit;
   if(prev_calculated==0)
      limit=0;
   else limit=prev_calculated-1;
//   int i=0;
//--- calculate MACD
   for(int i=limit;i<rates_total && !IsStopped();i++){
......
      int  RES=...
      int  B0=...
      int  B1=...
      int  B2=...
      int  B3=...
      Comment("RES=",RES,"  B0=",B0," B1=",B1," B2=",B2," B3=",B3);
      RESBuffer[i]=i%5;//RES;//ExtFastMaBuffer[i]-ExtSlowMaBuffer[i];
//--- calculate Signal
   }
...

The window is deleted, in the context menu - "delete indicator window" and"list of indicators" is greyed out, but the INDUKE LIKES TO LIKE WRITING COMMENTS FOR A FEW MINUTES...

What's this about?

 
THANK YOU!

THANK YOU!
Sorry, I got a bit excited. There is a problem after all. I'll put in a request for service-desk myself
