A hammer is a single candlestick with a small body near the top of its range and a long lower wick at least twice the length of the body, forming after a decline. It shows sellers pushed price down but buyers drove it back up by the close, a possible bullish reversal. It works best at support, after a clear downtrend, with confirmation from the next candle closing above the hammer's high. A stop usually goes below the hammer's low.
The hammer is one of the first candlestick patterns traders learn, and one of the most misused. On its own it's weak. At the right location with confirmation, it becomes a useful, clearly defined entry.
What a hammer looks like
- Small real body near the top of the candle's range (colour matters less than position).
- Long lower shadow, at least 2× the body length.
- Little or no upper shadow.
- Appears after a decline. Without a prior downtrend, it isn't a hammer in the classic sense.
A green hammer (close above open) is slightly stronger than a red one, because buyers finished the session in control.
The story behind the candle
- Price opens and sellers push it sharply lower (the long lower wick).
- Buyers step in at lower prices and push it back up.
- The candle closes near its high, so the sellers' push failed.
That failed push is the signal: selling pressure was absorbed. It doesn't mean buyers are now in charge. It means the decline may be losing steam.

How to trade a hammer
1. Location first. The best hammers form at support: prior swing lows, a rising moving average in a larger uptrend, a key daily level, or VWAP for intraday traders.
2. Wait for confirmation. The next candle closes above the hammer's high, or trades above it. This filters out many failures.
3. Entry. Buy on the break of the hammer's high (a buy stop), or on the confirmation close.
4. Stop. Below the hammer's low, plus a small buffer for noise, for example a fraction of ATR.
5. Target. The nearest resistance, or a fixed multiple of risk (2R). Given the long wick, the stop can be wide, so check that the reward-to-risk still makes sense.
6. Size from the stop. Shares = (account × risk %) ÷ (entry − stop). See position sizing.
When hammers fail
- In strong downtrends with no support nearby: the hammer is just a pause.
- On low volume: less conviction behind the rejection.
- Against the higher timeframe: a 5-minute hammer inside a daily breakdown is low-probability.
- Before major news: the next data release can overwhelm it.
Candlestick patterns on their own have modest predictive power in most studies. Their value comes from combining them with location, trend and confirmation, which is the idea of confluence. More patterns in our candlestick patterns cheat sheet.
A hammer checklist
- Prior decline? Yes / No
- At a defined support level? Yes / No
- Lower wick ≥ 2× body, close near high? Yes / No
- Confirmation candle? Yes / No
- Higher timeframe not strongly bearish? Yes / No
- Reward-to-risk ≥ 1.5–2R? Yes / No
Candle patterns are one of the variables in TRADZY's Void Engine score, weighted with structure, trend alignment, volume and key-level proximity, so a hammer in the wrong place scores low.
FAQ
Is a hammer candlestick bullish?
It's a potential bullish reversal signal when it appears after a decline, especially at support and with confirmation. Without context, it's weak.
What is the difference between a hammer and a hanging man?
They have the same shape. A hammer appears after a decline (potentially bullish), while a hanging man appears after an advance (potentially bearish).
Does the colour of a hammer matter?
Less than its location. A green hammer is slightly stronger because it closed above the open, but both colours can signal a reversal.
Where should I put my stop on a hammer trade?
Usually just below the hammer's low, with a small buffer for normal volatility.
How reliable is the hammer pattern?
On its own, only modestly. Reliability improves a lot at strong support, in the direction of the higher-timeframe trend, and with a confirmation candle.
