The hammer candlestick is one of the best-known bullish candlestick patterns. It is a single candle that appears after a fall and hints that sellers may be losing control. On its own it is only a hint, so this page covers how traders confirm it and how they plan the hammer stop loss, target and position size.
What a hammer looks like
- A small body near the top of the day's range. It can be green or red; a green body is read as slightly stronger.
- A long lower wick, at least about twice the length of the body.
- Little or no upper wick.
The story inside the candle: sellers pushed price well down during the session, buyers stepped in, and price closed near where it opened, close to the high.
What it suggests, and the trend context it needs
A hammer only counts after a downtrend or a clear pullback within an uptrend. In the middle of a sideways range, it says very little. It suggests that the selling may be exhausted, not that a rise has started.
Same shape after a rise: the hanging man
If the identical candle appears after a strong rise, it is called a hanging man, and it is read as bearish. The long lower wick now shows that sellers were able to drive price down sharply during the session, even though it recovered. The shape is the same; the trend before it changes the meaning.
How traders confirm it
- The next candle closes above the hammer's high. Many traders enter only then, often with a buy-stop just above that high.
- Location: a hammer at a known support level, a previous low or a rising moving average carries more weight than one in empty space.
- Volume: higher-than-usual volume on the hammer or the confirming candle suggests real buying rather than a quiet drift.
Stop-loss and target
The usual hammer stop loss goes just below the low of the hammer's lower wick. If price trades below that low, the buyers who defended it have failed and the idea is wrong.
For the hammer target, traders use either the nearest resistance above (a recent swing high or a broken support), or a reward-to-risk multiple such as 2R: twice the distance from entry to stop, added to the entry. If the nearest resistance is closer than 1R, the trade may not be worth taking.
Sizing the trade
Decide first how much of your account you are willing to lose if the stop is hit (your risk per trade). Then:
Shares = risk amount ÷ (entry − stop)
Example: a ₹5,00,000 account risking 1% has ₹5,000 at risk. Entry is ₹500 and the stop is ₹480, so the risk is ₹20 a share. ₹5,000 ÷ ₹20 = 250 shares, a position of ₹1,25,000. A 2R target would be ₹540. The Position Size Calculator does this arithmetic for you.
Common mistakes
- Calling every long-wicked candle a hammer, even in a sideways range or after a rise.
- Buying at the hammer's close instead of waiting for confirmation.
- Placing the stop too tight, inside the wick, where normal noise hits it.
- Ignoring a gap down the next day that opens below the stop; the loss can then be larger than planned.
- Sizing by "how many shares feel right" instead of by the stop distance.
How often it fails
Often. A hammer is a single day of price action, and markets frequently resume falling after one. Confirmation, location at support and a sensible stop improve the odds of a fair trade, but they do not make the pattern reliable, and no candle guarantees a rise. Treat it as a reason to plan a trade with a defined loss, not as a prediction.
