A hammer is a single candlestick with a small body near the top of its range and a long lower shadow, often at least twice the length of the body. It tends to appear after a fall in price. The shape tells a simple story: sellers pushed the market sharply lower during the session, then buyers stepped in and dragged it back up to close near where it opened. For beginners, it is one of the easiest candlestick patterns to spot, and one of the easiest to over-trust.
How to recognise a hammer
Look for three features. The body, which is the gap between the open and the close, is small and sits in the upper part of the candle. The lower shadow, or wick, is long, showing how far price dropped before recovering. The upper shadow is short or absent. The colour of the body matters less than the shape, though some traders give slightly more weight to a hammer that closes above its open.
Context is the fourth feature, and arguably the most important. A hammer only carries its usual meaning after a decline. The same shape in the middle of a sideways range, or after a strong rally, says much less. If you are new to reading candles, our guide on how to read a candlestick chart covers the basics of open, high, low and close.
What the hammer is trying to tell you
The long lower wick shows rejection. At some point in the session, lower prices were tested and failed to hold. That can hint that selling pressure is fading and that buyers are prepared to defend a level. It does not prove that a trend has turned. It shows one session in which the bears lost control of the close.
That is why many traders treat a hammer as a question rather than an answer. The next candle or two often matter more. A follow-through session that closes above the hammer’s high adds weight to the idea of a turn. A session that breaks below the hammer’s low suggests the rejection was temporary.
Hammer, hanging man and inverted hammer
Two close relatives cause confusion. A hanging man has the same shape as a hammer but appears after a rise. It hints that sellers tested lower prices during an uptrend, which some read as an early warning rather than a bullish sign. An inverted hammer flips the shape, with a long upper wick and a small body near the bottom, and also appears after a decline. The lesson is that identical shapes can mean different things depending on what came before. The doji candlestick is another indecision signal worth comparing.
Using a hammer with other evidence
Candlestick patterns work better when they line up with something else. A hammer forming at a well-tested support level carries more interest than one floating in empty space. Our guide to support and resistance explains how to find those levels. Volume, where available, can add context: a hammer on heavier activity suggests more participants were involved in the rejection.
Timeframe matters too. A hammer on a daily chart reflects a full day of trading. A hammer on a five-minute chart reflects five minutes, and the market produces a great many of those. The shorter the timeframe, the more noise you are reading.
Common mistakes
The most frequent error is acting on the shape alone, ignoring the trend and the level it formed at. Another is placing a stop too tight. If you treat the hammer as evidence of support, the logical place for a stop is usually below the low of the wick, because a break there undermines the idea. That can make the distance larger than beginners expect, which is why position size has to adjust rather than the stop being squeezed. A third mistake is assuming every long lower wick is a hammer, when the body and context do not fit.
Bringing it together
A hammer shows that sellers pushed hard and failed to hold their ground by the close. After a decline and near support, it can be an early clue that pressure is shifting. On its own, it is a single candle, and single candles are easily overwhelmed by the next headline.
