Heiken ashi smoothed – zone trade – indicator MetaTrader 5

Theory:

The original indicator was described by B. Williams as fourth dimension – Trading Zone:

• If the current bars of AC and AO are trending up, it shows that the zone is up
• If the current bars of АС and АО down, it shows that the zone is down.
• If the bars of AC and AO are differently directed then the bar is colored grey.

This version:

The indicator is based on the following 3 indicators:

• Heiken Ashi
  
• smoothed (if the smoothing period is >1)
• regular (if the smoothing period is <=1)
• Accelerator Oscillator.
• Awesome Oscillator.

Comparing the slope of the smoothed Heiken ashi can filter out some of the false signals. The combined states and values of the 3 are producing zones and trade signals. This version is adding the smoothing possibility using one of the 4 average types :

• simple moving average
• exponential moving average
• smoothed moving average
• linear weighted moving average
