Cleaned up my buggy indicator nicely.

Spécifications

So as the title suggest, I am looking for someone to debug and briefly explain my errors in my code.

The indicator looks like this on the chart

There are 4 bugs to fix

  1. Indicator applies to the chart fine but doesn't seem to run after initialization.
  2. Indicator only works on 1 hour charts and higher.
  3. Indicator "freezes" on start on new period.
  4. Graphic panel doesn't update to represent indicator value.

Examples of coding include the following

  • Custom strength algo 

   int   i,pos;

////---
   if(rates_total<=1)
      return(0);

////--- preliminary calculation
   if(prev_calculated>1) pos=prev_calculated-1;
   else  pos=1;

   for(i=pos-1; i<rates_total; i++)
     {double eg = 50 + (((iClose("EURGBP",0,i)-iClose("EURGBP",0,(i+Delta)))/(iHigh("EURGBP",0,(iHighest("EURGBP",0,MODE_HIGH,Delta,i)))-iLow("EURGBP",0,(iLowest("EURGBP",0,MODE_LOW,Delta,i)))))*100)/2;
