[DEM] Heikin Ashi Barcolors

[DEM] Heikin Ashi Barcolors is designed to apply smoothed Heikin Ashi calculations to regular candlestick charts and color the price bars based on the resulting Heikin Ashi trend direction to reduce market noise and provide clearer visual trend identification. The indicator first applies EMA smoothing to the standard OHLC values, then calculates Heikin Ashi values using the traditional formulas (averaged close, modified open based on previous values, and adjusted high/low), and applies an additional layer of EMA smoothing to the Heikin Ashi results. The bars are colored teal when the smoothed Heikin Ashi close is above the smoothed Heikin Ashi open (indicating bullish conditions) and red when the close is below the open (indicating bearish conditions), effectively transforming the visual appearance of regular candlesticks to reflect the smoother, trend-following characteristics of Heikin Ashi methodology while maintaining the original price structure.
