Calculation

//period = user defined, default is 14
//top guide = user defined, default is (fibonacci number) 61.8
//bottom guide = user defined, default is (fibonacci number) 38.2
//index = current bar number

   atr = atr(index, period);
   total = sum(index, period, ATR);
   lowest = lowest(index, period, LOW);
   highest = highest(index, period, HIGH);
   diff = highest - lowest;
   temp = (total/diff);
   Plot: chop = 100 * Math.log10(temp) / Math.log10(period);
