Hammer: The Bullish Reversal Candle at the Bottom
A Hammer has a small body at the top and a long lower wick — sellers pushed price down hard during the session, but buyers stepped in and drove it back up. When it appears at the bottom of a downtrend, it is one of the most reliable bullish reversal signals in candlestick analysis.
The Hammer gets its name from the idea of hammering out a bottom. During the session, sellers drive price aggressively lower — creating the long handle. But at the lows, buyers arrive with force, absorbing all the selling and driving price back up to close near the session high. The result is a candle that looks like a hammer: small head at the top, long handle pointing down.
Hammer — long lower wick (≥ 2× the body) at the bottom of a downtrend. Buyers defended the lows.
Anatomy of a Hammer
| Feature | Requirement |
|---|---|
| Body | Small — should occupy the upper portion of the candle's total range |
| Lower wick | At least 2× the body length. The longer, the stronger the signal. |
| Upper wick | None or very small — if there is a significant upper wick, it is less clean |
| Position | Appears at the bottom of a downtrend or at a support level |
| Colour | Can be green or red — green is stronger (closed above open as well as recovering the range) |
Why the Hammer Is Bullish
The lower wick tells the story. For price to form a long lower wick, sellers had to push it down significantly — and then buyers had to push it all the way back up. That tug-of-war, won decisively by buyers by the close, indicates strong buying interest at those lower prices. The market has said: this is too cheap, buyers will defend it.
Hammer at Support
Price has been falling for two weeks and reaches a key support zone at ₹480. On the day of contact, price opens at ₹484, drops to ₹465 during the session, then recovers strongly — closing at ₹482. The lower wick spans ₹17, the body spans ₹2. A clear Hammer. The next day opens at ₹484 and closes at ₹495. Traders who entered on the confirmation candle ride the recovery from ₹484 toward prior resistance.
Green Hammer vs Red Hammer
Both are valid — but they tell slightly different stories:
| Green Hammer | Red Hammer | |
|---|---|---|
| Close vs open | Close above open — buyers won the session entirely | Close below open — buyers recovered the range but not the open |
| Signal strength | Stronger — full buyer control by close | Valid but slightly weaker |
| Implication | Buyers dominated sellers by end of session | Buyers fought back strongly but sellers kept a small edge |
The Difference Between a Hammer and a Dragonfly Doji
They look similar — both have long lower wicks and small or absent upper wicks. The distinction is the body size. A Hammer has a visible body — open and close are different enough to see. A Dragonfly Doji has essentially no body — open and close are nearly identical. In practice, both signals are interpreted similarly: bullish reversal at the bottom.
What Comes Next: Confirmation
Never trade a Hammer on its own. The next candle determines whether the signal is real:
- Bullish confirmation: next candle opens above the Hammer body and closes higher — enter long
- Gap up on the next open: strong confirmation — consider entering on the gap or first pullback
- Bearish next candle that closes below the Hammer low: signal failed — do not enter, or exit quickly
The Hammer's Low Becomes Your Stop Reference
Once confirmed, the low of the Hammer's wick is the reference for your stop-loss. If price returns below that level after your entry, the buyers who drove the recovery have been overwhelmed — the premise of the trade is broken. Keep the stop just below the Hammer's wick low.
A Hammer in the Middle of an Uptrend Means Nothing
The Hammer only matters at the bottom of a downtrend or at support. A candle with the same shape appearing mid-trend or at the top of a move is not a Hammer — it is just a candle with a long lower wick. The name and the signal are tied to context, not just shape.
Key Takeaways
- A Hammer has a small real body at the top of its range and a lower wick at least twice the body's length.
- It forms when sellers push price down during the session but buyers recover it to close near the high.
- Bullish context is essential — a Hammer is only meaningful at the bottom of a downtrend or at support.
- A green (bullish) Hammer is stronger than a red one — buyers not only recovered but closed above the open.
- Confirmation from the next candle (a bullish close above the Hammer's body) is required before acting.
