Heiken Ashi ZoneTrade

This script is based on this trading approach that integrates Acceleration/Deceleration Technical Indicator (AC) and Awesome Oscillator (AO) into the Heiken Ashi candlestick chart.

Accoding to the developer of the ZoneTrade indicator it is working in this way:
If the current bars of AC and AO are green, it shows that the zone is green.
If the current bars of АС and АО red, it shows that the zone is red.
If the bars of AC and AO are differently directed then the bar is colored grey (grey zone).
