ChartIndicatorAdd and drawing style

[Nicola Grippaldi]

I tested the EA in https://www.mql5.com/en/docs/chart_operations/chartindicatoradd and works well.

Now I wish modify indicator's style/width/color, is there a way?

Thanks

I tried this solution, but doesn't work

//+------------------------------------------------------------------+
//| Expert initialization function                                   |
//+------------------------------------------------------------------+
int OnInit()
  {
   int indicator_handle=iMA(Symbol(),0,_period,_shift,MODE_SMA,apr);
   if(indicator_handle==INVALID_HANDLE)
     {
      Print("Failed to create MA indicator. Error code ",GetLastError());
      return(INIT_FAILED);
     }
   bool added=ChartIndicatorAdd(0,0,indicator_handle);
   if(!added)
     {
      PrintFormat("Failed to add MA indicator on %d chart window. Error code  %d",
                  0,GetLastError());
      return(INIT_FAILED);
     }
   PlotIndexSetInteger(0,PLOT_LINE_STYLE,STYLE_DASHDOT);     //  <------------------------- does nothing
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |

void OnTick()
  {
// Expert Advisor performs nothing
  }

You can't change indicator's style/with/color by "external" code, you can only do it within the indicator.

ok, thanks anyway

Add input parameters to indicator and then you can change them from external ea.
