Heiken Ashi Smoothed indicator is a modified standard Heiken Ashi indicator.

The difference is that it uses smoothed price time series values instead of current ones. Such method allows to filter many false signals that could possibly have appeared, in case the indicator had been calculated in a standard way.

The indicator allows to select the type of smoothing from the dozen of possible variants:

  1. SMA - simple moving average;
  2. EMA - exponential moving average;
  3. SMMA - smoothed moving average;
  4. LWMA - linear weighted moving average;
  5. JJMA - JMA adaptive average;
  6. JurX - ultralinear smoothing;
  7. ParMA - parabolic smoothing;
  8. T3 - Tillson's multiple exponential smoothing;
  9. VIDYA - smoothing with the use of Tushar Chande's algorithm;
  10. AMA - smoothing with the use of Perry Kaufman's algorithm.

It should be noted that Phase1 and Phase2 parameters have completely different meaning for different smoothing algorithms. For JMA it is an external Phase variable changing from -100 to +100. For T3 it is a smoothing ratio multiplied by 100 for better visualization, for VIDYA it is a CMO oscillator period and for AMA it is a slow EMA period. For AMA fast EMA period is a fixed value and is equal to 2 by default. The ratio of raising to the power is also equal to 2 for AMA.

The indicators use SmoothAlgorithms.mqh library classes (must be copied to the terminal_data_folder\MQL5\Include). The use of the classes was thoroughly described in the article "Averaging Price Series for Intermediate Calculations Without Using Additional Buffers".

The indicator is built in two variants - for a chart's main window:

Heiken_Ashi_Smoothed

And for a chart's additional window:

Heiken_Ashi_Smoothed_
