Hammer candlestick: what it means and how to spot one
A hammer candlestick has a small body on top and a long lower wick after a fall. Learn what it shows, how it differs from a hanging man, and spot one.
A hammer is a candle with a small body near the top and a long lower wick, after a decline. On this site: body at most 35% of the range, lower wick at least 2x the body, upper wick at most 15% of the range, after closes fell at least 2% over 5 candles. It shows buyers rejecting lower prices.

How to identify it (the exact rules)
These are the rules this site uses to build and grade every chart. Traders do not all use the same numbers; ours are published so you can check every answer (see the methodology).
- Hammer, hanging man, shooting star, inverted hammer: body more than a doji's and at most 35% of the range.
- Hammer family: the long wick is at least 2 times the body.
- Hammer family: the other wick is at most 15% of the range.
- Prior trend measured on the closes of the 5 candles before the pattern.
- A prior trend needs a move of at least 2% over that lookback.
- Hammer: the long wick is the lower one and the prior trend is down. Hanging man: the same shape after an uptrend.
What a hammer shows
The market has been falling. A new period opens and sellers push price lower again, maybe to a new low. Then something changes. Buyers step in and lift price most of the way back up. By the close, price sits near the top of the period's range, close to where it opened.
That story is drawn by the long lower wick. The wick is the ground sellers took and then lost. The small body at the top says the period ended near its high. The missing upper wick says buyers did not push past the open by much: they repaired the damage, they did not take over.
The color of the body matters less than people think. A green hammer closed a little above its open, a red one a little below. Both show the same rejection of the low.
Two versions of the same shape
The hammer shape has two names, and only the trend before it decides which one you are looking at.
| Name | Same shape? | Trend before it | What it suggests |
|---|---|---|---|
| Hammer | Yes | Falling (closes down 2%+ over 5 candles) | Sellers may be running out of strength |
| Hanging man | Yes | Rising (closes up 2%+ over 5 candles) | Sellers showed up inside an uptrend |
The two charts above each end on a shaded candle with this shape, and you decide: hammer or hanging man? One chart shows each. The candles are built the same way, so the only clue is the trend that leads into them.
Most often confused with: the hanging man
This is the classic trap. A hammer and a hanging man are the same candle. If you only look at the candle, you cannot tell them apart. You have to look left.
After a fall, the long lower wick reads as buyers defending a low. After a rise, the same wick reads differently: during an uptrend, sellers managed to drag price far down within one period, even if it recovered. That is a warning sign inside strength, not a sign of support. The name changes because the story changes.
A quick habit: before you name any long-lower-wick candle, check the closes of the five candles before it.
What a hammer does not tell you
- That the fall is over. It shows one period of rejection. The next period can open and fall straight through it.
- How far a bounce could go. The candle says nothing about size or targets.
- Why buyers stepped in. It could be a real level of demand or just short sellers closing out.
- Anything on its own in a flat market. Without a prior decline, this site does not call it a hammer at all.
How reliable is it?
No honest source can give you a hammer success rate that holds across markets and years. Researchers have tested whether candlestick strategies create value for investors (for example Marshall, Young and Rose, 2006, in the sources); results depend on the market, the period and trading costs, and no pattern comes with a dependable success rate. The hammer is useful for reading the battle inside a period, not as a forecast you can count on.
Where the idea is proven wrong
The hammer's whole argument is that buyers defended its low. So the low is the line that matters. If price later closes below the hammer's low, the defense failed and the hammer's reading no longer holds. A close back above the hammer's high, on the other hand, is the follow-through the pattern's logic hopes for. Many chart readers wait to see that next candle before treating a hammer as meaningful.
Frequently asked questions
Is a hammer candlestick bullish?
It is read as a possible bullish reversal because it shows buyers rejecting lower prices after a fall. But it is only one candle. Many hammers are followed by more selling. Chart readers usually look for the next candle to close higher before giving it weight.
Does the color of a hammer matter?
Less than the shape and the context. A green hammer closed slightly above its open, which some readers see as a bit stronger. A red hammer closed slightly below its open. Both show the same long lower wick and the same rejection of the low.
What is the difference between a hammer and a hanging man?
They are the same shape: small body on top, long lower wick, tiny upper wick. A hammer comes after a decline, a hanging man after a rise. On this site the prior trend is a move of at least 2% in the closes over the 5 candles before.
How long should a hammer's lower wick be?
On this site, the lower wick must be at least twice the length of the body. The body itself can be at most 35% of the candle's full range, and the upper wick at most 15%. Many books use a similar two-times rule.
What happens if price falls below a hammer?
Then the hammer's idea has failed. The pattern's logic was that buyers defended its low. A close below that low means sellers broke through the level buyers had defended, and the reading of the candle no longer applies.
