Trading Long K-Line Shadows as Reversal Signals with Context Filters
Summary
This article explains how candlestick shadows represent the distance between an intraperiod extreme and the candle body, and interprets long upper and lower shadows as possible signs of rejected price moves. It proposes using a long upper shadow after a substantial rise as a short signal, and a long lower shadow after a substantial fall as a long signal. The strategy compares each shadow with the candle body and the opposite shadow, using separate coefficients for the two directions; corresponding conditions are also given for closing positions.
The text argues that ordinary shadows are common and should not automatically trigger trades, so relative length and prior market movement act as filters. It offers a rules based example and code implementation, but provides no backtest results or performance measurements. The author cautions that real price behavior does not always follow classical candlestick interpretations: the signals express probabilities, not certainty. The explanation is framed partly around futures, where the author suggests rises and falls may differ in speed, but does not specify a tested instrument, timeframe, or coefficient values.
Key ideas
- A candle's upper and lower shadows mark how far prices moved beyond its body during the period.
- A long upper shadow after a substantial rise is treated as a possible bearish reversal signal.
- A long lower shadow after a substantial decline is treated as a possible bullish reversal signal.
- The proposed rules compare shadow length with the body and the opposite shadow, using distinct directional coefficients.
- The article gives no measured results and warns that candlestick patterns are probabilistic.
