Short-Term Reversal Signals from Candlestick Shadows

Summary

This short-term countertrend approach uses the upper and lower shadows of candlesticks to identify possible price rejection. A large upper shadow is interpreted as fading buying pressure, while a large lower shadow suggests selling pressure may have been absorbed. The strategy compares each shadow with a recent average scaled by a configurable factor, then uses shadow-derived stop prices when switching between long and short positions.

The document frames the method as a high-frequency strategy intended for three-minute Coinbase candles and includes configurable lookback and scaling parameters. However, its published backtest settings instead specify BTC/USDT futures, a three-hour chart period, and a fifteen-minute base period for December 2023. No performance results are supplied, and the source uses substantial simulated slippage. Shadow size alone may not predict reversals reliably; stop placement, transaction costs, and position management therefore need careful evaluation. ATR stops and additional sentiment or statistical filters are suggested as possible extensions.

Key ideas

• The strategy looks for countertrend entries when candlestick shadows are unusually large relative to a recent average.
• An upper shadow is treated as possible weakening in buying pressure, while a lower shadow suggests possible weakening in selling pressure.
• Shadow-based price levels guide stops when the position changes direction.
• The stated three-minute Coinbase context does not match the published futures backtest timeframe settings.
• The document gives no performance results and notes uncertainty in reversal prediction and stop placement.
