Hammer vs Doji: Two Reversal Candles, Very Different Signals
The Hammer and Doji are both single-candlestick patterns that can signal potential reversals. However, they have very different structures and convey different levels of conviction. Understanding the distinction is crucial for accurate chart reading.
Structure Comparison
| Feature | Hammer | Doji |
|---|---|---|
| Body size | Small body at top | Virtually no body (open ≈ close) |
| Lower shadow | Long (2x+ body length) | Variable |
| Upper shadow | Very small or none | Variable |
| Signal strength | Strong bullish reversal | Indecision (neutral) |
| Context needed | Must be at support/downtrend | Always needs confirmation |
| Win rate | ~62% at support | ~52% (lower without context) |
| Color matters? | Green hammer is stronger | Color irrelevant |
The Hammer: Bullish Conviction
The Hammer shows that sellers pushed the price significantly lower during the period, but buyers stepped in strongly and pushed it back up near the open. This demonstrates clear buying conviction at that price level. When it appears at a support level after a downtrend, it is a strong bullish reversal signal.
The Doji: Market Indecision
The Doji shows that buyers and sellers were in perfect equilibrium — the price opened and closed at virtually the same level. This signals indecision, not a clear directional bias. A Doji requires strong confirmation from the next candle before acting on it.
Trading Rules
Hammer: Enter long when a Hammer forms at a key support level. Stop below the Hammer's low. Target the next resistance level.
Doji: Wait for the next candle to confirm direction. If the next candle is strongly bullish, consider a long entry. If strongly bearish, consider a short.
