High Low Rate Of Change

An experimental indicator using Pine Script Arrays. The indicators measures the rate of change of the highest highs and lowest lows. I call it the "High Low Rate of Change".
The H/L Rate of Change indicator finds the delta between the current highest high and previous highest high and after some filtering places these values into an array.
Same goes for the lowest lows.
In the end Sum it all up into the Histogram with optional smoothing using Exponential moving average (EMA).
