The hammer is one of the most recognisable candlestick patterns — a single candle that can mark the end of a fall. It's easy to spot once you know the shape, and it tells a clear story about buyers stepping in.
What a hammer looks like
A hammer is a single candle with three features:
- A small body near the top of the range.
- A long lower wick (shadow) — at least about twice the length of the body.
- Little or no upper wick.
The result looks like a hammer (or a square lollipop on a long stick). The colour of the body matters less than the shape — a hammer can be green or red.
The story it tells
A hammer forms when price drops sharply after the open but rallies back to close near the high. In other words, sellers pushed the market well down during the session, but buyers fought back and reclaimed almost all the lost ground by the close.
That long lower wick is the key: it shows selling pressure was rejected. When this happens at the bottom of a downtrend, it hints that sellers are losing control and a reversal upward may be coming.
Note
Context is everything. The same candle shape at the top of an uptrend is called a hanging man and carries a bearish warning. A hammer only counts as bullish when it appears after a decline.
Why confirmation matters
A hammer is a signal of possibility, not a guarantee. On its own, one candle can be noise. Experienced traders wait for confirmation before acting — usually a strong bullish candle on the next period, or price pushing above the hammer's high.
Confirmation filters out false alarms. A hammer followed by more selling was just a pause; a hammer followed by a strong up-close is a much more convincing reversal.
What makes a hammer stronger
Not all hammers are equal. A hammer is more meaningful when:
- It appears after a clear, extended downtrend — there needs to be a decline to reverse.
- It forms at a support level or a moving average that has held before.
- Its lower wick is long relative to recent candles, showing a big rejection.
- The next candle confirms with strength.
A tiny hammer in the middle of a choppy, sideways market means very little.
Risk
No candlestick pattern is a sure thing. Even a textbook hammer can fail. Always use a stop loss — often placed just below the hammer's low — and never risk more than you can afford to lose.
The inverted hammer
There's a cousin worth knowing: the inverted hammer. It has the same small body but a long upper wick and little lower wick, and it also appears after a downtrend. It suggests buyers tried to push price up — a tentative sign of a possible bottom that, like the hammer, needs confirmation.
How to practise spotting hammers
- Open a daily chart of a major pair like EUR/USD.
- Look for candles with tiny bodies and long lower wicks after a fall.
- Check whether a bounce followed — and whether it happened at support.
- Test what you see on a demo account so there's no money at risk while your eye trains.

The bottom line
A hammer is a single candle with a small body and a long lower wick that forms after a decline — a sign that sellers were rejected and a reversal may be near. It's strongest at support and after a clear downtrend, but it always needs confirmation from the next candle before you act. Spot it, wait for proof, and manage your risk.
