[DEM] Doji Candlestick Identifier

[DEM] Doji Candlestick Identifier is designed to automatically detect and highlight doji candlestick patterns on the price chart by identifying bars where the opening and closing prices are nearly identical, indicating market indecision. The indicator uses statistical analysis to determine what constitutes a "near identical" open-close relationship by calculating the standard deviation of close-open differences over a specified lookback period (default 200 bars) and setting tolerance bands at one-tenth of this deviation above and below zero. When a candlestick's open-close difference falls within these narrow tolerance bands, the indicator places a small gray triangle below the bar to mark the doji pattern, helping traders quickly identify potential reversal or continuation points where buying and selling pressure are balanced.
