I need an help with this monitor

New comment
 

Hi all, could you indicate the mistakes in this indicator monitor?

I'm trying to write this indicator to monitor the global variables in my expert, but I don't find the errors...

Thank you!

Your code didn't call any function :

int start()
 {

 }

You should write this code inside start() function :

int start()
 {
  CreateLabels();
 }

Thank you!

Thank you!

You're welcome

Ok now my monitor works better.

I wrote the following code to delete the objects related to the closed orders, but it does not work well. Could you help me? Thank you!

void DeleteLabels()
 { 
 int obj_total=ObjectsTotal();
     
     for(int ww=obj_total-1;ww>(OrdersTotal()+1)*9;ww--)
     {
     string name=ObjectName(ww);
     ObjectDelete(name);
     }
 }

In the first rows I see the market ticket and it's ok.

Then I see the closed orders, but I don't want to see them.

int total = OrdersTotal();

 for(int cnt=0;cnt<=total;cnt++){
     OrderSelect(cnt, SELECT_BY_POS, MODE_TRADES) ;
                    
       int a = 1 + cnt ;
       ObjectCreate("a", OBJ_LABEL, 0, 0, 0, 0);
  1. If there are total orders, their positions are zero to total orders minus one. Your last select always fails but since you don't check everything after that is BOGUS. Check your return codes for errors and report them.

  2. You are creating object using position as a name. As older orders get closed, position indexes change. You can't create new objects with the same old names. Don't use non-unique names (position,) use ticket.
