Vertical Line - MetaTrader 5 Script | Forex Indicator Download - MT4/MT5 Resources - MetaTrader 5 Resources

The indicator draws a vertical line (OBJ_VLINE) and then moves it to the specified time (hours and minutes).

Input parameters :

Use Hours and Minutes Only " Use Hours and Minutes Only " range.

The vertical line is drawn for the current day. If a new day starts, the row will be moved to the new day and set to the specified hour and minute.

The indicator has built-in protection against accidental deletion of vertical lines: a timer periodically checks whether the line exists on the chart. If a vertical line (OBJ_VLINE) is not found, the static variable "prev_date" declared at the global program level is reset to zero:

 //+------------------------------------------------------------------+
//|Timer function |
//+------------------------------------------------------------------+
blank timer ()
  { //--- prevent unauthorized deletion if ( object lookup ( 0 ,Inp name) < 0 )
    {
      Previous date = 0 ;
      VLine creation ( 0 , Inp name, 0 , 0.0 , Inp color, Inp style, Inp width);
    }
  }

This will cause a new vertical line to be created in OnCalculate():

 if (previous date == 0 ) // first start {
Mql date time string input;
BuildTime (InpTime, str_input);
      str_to_draw.hour=str_input.hour;
      str_to_draw.min=str_input.min;
      str_to_draw.sec= 0 ;

      PreviousDate = struct to time (str_to_draw);
      V line movement ( 0 ,InpName,prev_date);

return (rate_total);
    }
