A simple code MT5 required

Hello 

My Order is simple 

I want a code that calculate the summation of upper shadows for  i candles (3,4,5  15 etc) By Loop function

Meaning:  from shift 1 to 5 the total upper shadow lengths is called for exampl up = 125 (by points )

The same for lower shadows on MT5 editor 

This is for help and clarify the need 

 double DN,UP;

   for(int i=0;i<Candles_Number;i++)

   {

      if(Close[i]>=Open[i])

      {

         DN=DN+(Open[i]-Low[i]);

         UP=UP+(High[i]-Close[i]);

      }

      else if(Close[i]<Open[i])

      {

         DN=DN+(Close[i]-Low[i]);

         UP=UP+(High[i]-Open[i]);

   }

but it did't work with me
