What Is a Hammer Candlestick?
A hammer is a single candlestick with a small body up top and a long lower wick hanging below it — like a hammer's head and handle. That long wick tells a quick story: sellers dragged the price down during the session, but buyers fought back and pushed it up again before the close.
To read this guide it helps to know the basics of how candles are built — if the words "body" and "wick" are new, start with candlestick basics, which explains that each candle shows the open, high, low and close for a period.
The anatomy of a hammer
Every candlestick has two parts: the body (the thick block between the open and close) and the wicks or shadows (the thin lines showing the highest and lowest prices reached). A hammer has a very specific shape:
- A small body near the top of the candle's range. The open and close are close together.
- A long lower wick — usually at least about twice the height of the body. This is the defining feature.
- Little or no upper wick. Price didn't spend much time above the body.
Put together, it looks like a hammer standing on its handle: a compact head sitting on a long shaft.
What the shape is telling you
The long lower wick is the whole point. It means that at some stage sellers were firmly in charge and forced the price sharply lower — but by the end of the session, buyers had stepped in and lifted it most of the way back. Traders describe this as rejection of lower prices: the market tried to go down, and something pushed it back.
When a hammer shows up after a stretch of falling prices, some see it as an early hint that selling pressure may be easing. That's why it's classed as a potentially bullish candle. But "potentially" is doing a lot of work in that sentence — a single candle is a snapshot of one session, not a forecast.
Context changes everything
The same shape means different things depending on where it appears — which is why the exact same candle has two names:
- Hammer: appears after a downtrend, read as a possible sign the decline is losing steam.
- Hanging man: the identical candle appearing after an uptrend, read instead as a possible warning sign.
So the candle by itself doesn't carry a fixed meaning — where it forms is half the story. Traders also look at what happens in the sessions after a hammer, and often at nearby support and resistance levels, before reading much into it. A hammer that forms right at a long-standing support level draws more attention than one floating in the middle of nowhere.
The bottom line
A hammer is a small-bodied candle with a long lower wick, showing that sellers drove price down during a session but buyers pulled it back up — a rejection of lower prices. After a downtrend it's read as a potentially bullish hint; the same shape after an uptrend is called a hanging man and read as a warning. Either way, one candle is only a small clue. What it's really showing you is the balance of buyers and sellers over a single period, and that alone never predicts the next move.
Frequently asked
What is a hammer candlestick?
A hammer is a single candlestick with a small body near the top and a long lower wick (shadow) at least about twice the body's length, with little or no upper wick. The long lower wick shows that sellers pushed price well down during the session, but buyers stepped in and lifted it back up before the close. Traders read it as a sign of rejection of lower prices.
Is a hammer candlestick bullish?
A hammer is generally read as a potentially bullish signal, especially when it appears after a decline, because it shows buyers absorbing selling pressure. But a single candle is only a hint, not a prediction — context and what follows matter far more. On its own, one candle guarantees nothing about the next move.
What is the difference between a hammer and a hanging man?
They are the same shape — a small body with a long lower wick — but named differently based on where they appear. A hammer forms after a downtrend and is read as a possible bottoming hint, while a hanging man forms after an uptrend and is read as a possible warning. The identical candle is interpreted differently purely by context.
Does the colour of a hammer candle matter?
The colour (whether it closed slightly up or down) matters less than the shape. A green or hollow hammer, where price closed above the open, is sometimes seen as marginally stronger, but the key feature is the long lower wick showing rejection of lower prices. Many traders treat both colours as the same signal.
