If I change timeframe button status changed auto

New comment
Hi,
I'm new to mql4 programing I try my best to learn it.
I did some modification to an alerting to have it as a buttons in the chart window.

The problem that I face is when " I active the alert button and change timeframe the status of the alert button changed to false".


#property indicator_chart_window

      extern int Button_CORNER = 1;
      extern int Button_X = 165;
      extern int Button_Y = 278;
      int Button_XSIZE = 80;
      int Button_YSIZE = 18;
      extern int Button_Text_FontSize =7;
      string Sto_Button   = "Button_toggle";
      bool Alert_On   = True;

Hi GumRai,

Thank you for your reply. I test it but it still if i change timeframe the button change from "Sto Aleert ON" to "Sto Aleert ON""Sto Aleert OFF"?


   if(Alert_On ==0 )
      ObjectSetString(0,Button,OBJPROP_TEXT,"Sto Alert ON");
   else
      ObjectSetString(0,Button,OBJPROP_TEXT,"Sto Alert OFF");
}

The problem that I face is when " I active the alert button and change timeframe the status of the alert button changed to false".

I thought that you were referring to the button state. ie. pressed or not pressed

Yes Plese see the attacged photo



Try these changes

void OnDeinit(const int reason)
  {
  
  if(reason==REASON_REMOVE || reason==REASON_RECOMPILE)
    ObjectDelete("Button_toggle");
  return;
  }

OnDeinit to replace

//+------------------------------------------------------------------+

int deinit()
{
 
   ObjectDelete("Button_toggle");
 
   return(0);
}
thank you very much
