The hammer candlestick is a widely recognized bullish reversal pattern in Japanese candlestick charting. Contrary to traditional trading advice, historical backtesting reveals it performs best as a bearish continuation signal across all markets. This guide explores its identification, trading strategies, and evidence-based performance metrics.
What Is a Hammer Candlestick Pattern?
Characterized by a small real body and a long lower shadow (at least 2x the body length), the hammer resembles a hammer's shape. It forms exclusively in downtrends, signaling potential bullish reversals—though data suggests trading it inversely yields superior results.

- Minimal/no upper wick
- Prominent lower shadow (≥2x body height)

Optimal Bearish Continuation Strategy
