Resistance & Support - MetaTrader 5용 지표

Resistance and support lines are drawn based on the iFractals indicator. The indicator takes into account the fact that the last value of Fractals can be redrawn, therefore +5 additional bars are analyzed:

//--- number of values copied from the iFractals indicator 
   int values_to_copy=-1;
//--- if it is the first start of calculation of the indicator
   if(prev_calculated==0)
      values_to_copy=rates_total;
   else
     {
      //--- it means that it's not the first time of the indicator calculation, and since the last call of OnCalculate() 
      //--- for calculation not more than one bar is added 
      //--- value "+5" - because of the feature of drawing fractals
      values_to_copy=(rates_total-prev_calculated)+5;
     }
