This is a "combo" on 2 indicators: The Candle Pattern Indicator and the Candle Pattern Scanner.
The "indicator" detects and identifies popular candle patterns on the chart.
The "scanner" further enhances this capability by simultaneously analysing multiple instruments at 3 different time-frames. The indicator displays a “mini-chart” for each specified instrument and time-frame combination, showing the currently identified candle pattern (if any).
The following patterns are supported: Doji, Spinning Top, Hammer, Shooting Star, Inverted Hammer, Hanging Man, Marubozu, Bullish Engulfing, Bearish Engulfing, Piercing Line, Dark Cloud, Bullish Harami, Bearish Harami, Morning Star, Evening Star.
Alert notifications are also possible. When alerts are enabled, the indicator will cause an alert (pop-up alert and/or sound) whenever a new candle pattern is detected.
