Hammer
bullish reversal signal · 1 candle · reliability 4/5
A one-candle bullish reversal pattern that appears after a downtrend, with a small body near the top and a long lower wick.
The Hammer signals a return of buying pressure during a downward move. Its body sits near the top of the candle, while the lower wick is at least twice as long as the body. The long lower shadow shows that sellers pushed price down, but buyers drove it back up by the close. The pattern is valid when it appears after a downtrend, ideally near support.
What does it signal? A Hammer at the end of a downtrend is a potential reversal signal — sellers pushed price lower, but buyers took control before the close.
When is it reliable? At a strong support level, with above-average volume and a confirming green candle in the next period.
When to avoid it? Sideways markets and very short time frames such as 1-minute or 5-minute charts — noise is too high and the signal has little statistical value.
Anatomy and identification rules
Candle anatomy
- 1
Small body, green or red, in the upper third of the candle
- 2
Long lower wick — at least twice the length of the body
- 3
Upper wick is short or absent
- 4
The shape resembles an upside-down hammer
Identification rules
- Forms at the end of a downtrend — in an uptrend, the same shape is a Hanging Man
- Lower wick is at least 2× the length of the body
- Upper wick is no more than 30% of the body length
- Body color can be green or red — green gives a stronger signal
- Confirmation required: the next candle closes with a green body
Pattern in chart context
What it says about the market
Context of appearance: The Hammer is most reliable at the end of a downtrend, near a support level, or when RSI is oversold. Higher-than-average volume strengthens the signal.
Market psychology in three steps
- 1
Downtrend continues. Several candles print lower highs and lower lows. Sellers control the market, and sentiment remains negative.
- 2
Hammer forms. Selling pressure fades and buyers step back in. Price is pulled back near its starting point, creating the possibility of a reversal.
- 3
Confirmation arrives. The next candle closes with a green body, ideally on higher volume. Sentiment has shifted, and a new uptrend begins.
Same shape, opposite meaning
The Hammer and the Hanging Man look identical. The difference lies in context — mistake one for the other and you enter in the opposite direction. The candle shape alone is never enough: always read the trend first, then the pattern.
Most common mistakes
-
Ignoring context. A Hammer only makes sense at the end of a downtrend. In a sideways market or an uptrend, the same shape carries a different meaning — check the trend first.
-
Entering right after the pattern closes. The pattern itself is not an entry trigger — wait for the confirming green candle to close. Patience means fewer false signals.
-
Using too short a time frame. On 5-minute candles, most reversal patterns are just noise. Daily and 4-hour time frames tend to produce the highest hit rate.
-
Ignoring volume. A Hammer on low volume is a weak signal. With above-average volume, a reversal is more likely. Check the volume bar.
