Smoothed Heiken Ashi Trend Filter

This indicator applies the Heiken Ashi technique with added smoothing and trend filtering to help reduce noise and improve trend detection.

Components of the Indicator:
Heiken Ashi Calculations:

Heiken Ashi Close (ha_close): This is the smoothed average of the current bar’s open, high, low, and close prices, calculated with a simple moving average (SMA) to filter out noise.
Heiken Ashi Open (ha_open): This is the average of the previous Heiken Ashi Open and the current Heiken Ashi Close. It’s also initialized to smooth the transition on the first bar.
Heiken Ashi High (ha_high) and Low (ha_low): These values are calculated as the highest and lowest values among the high, Heiken Ashi Open, and Heiken Ashi Close for each bar.

Smoothing and Noise Reduction:

Smoothing Length: The indicator applies a smoothing length to the Heiken Ashi Close, calculated with an SMA. This reduces minor fluctuations, giving a clearer view of the price action.
Minimum Body Size Filter: This filter calculates the body size of each Heiken Ashi candle and compares it to a percentage of the Average True Range (ATR). Only significant candles (those with larger bodies) are plotted, reducing weak or indecisive signals.

Trend Filtering with Moving Average:

The indicator uses a simple moving average (SMA) as a trend filter. By comparing the Heiken Ashi Close to the moving average:
Bullish Trend: The Heiken Ashi candle is green when it’s above the moving average.
Bearish Trend: The Heiken Ashi candle is red when it’s below the moving average.

How to Use This Indicator:
Trend Identification:

Green candles signify a bullish trend, while red candles signify a bearish trend.
The smoothing and trend filtering make it easier to identify sustained trends and avoid reacting to short-term fluctuations.

Filtering Out Noise:
Minor price fluctuations and small-bodied candles (often resulting in indecisive signals) are filtered out, leaving only significant signals.

Adjustable Parameters:
Smoothing Length: Controls the degree of smoothing applied to the Heiken Ashi Close value. Increasing this value will make the Heiken Ashi candles smoother.
Minimum Body Size: This is a percentage of the ATR, used to filter out small or indecisive candles.
Trend Moving Average Length: Controls the period of the moving average used as a trend filter.
This Smoothed Heiken Ashi Trend Filter indicator is useful for identifying trends and filtering out noisy signals. By smoothing and filtering, it helps traders focus on the overall trend rather than minor price movements.
