Hammer Candlestick: Reversal After Downtrend
The hammer candlestick forms after a downtrend and signals a potential bullish reversal.
What Is a Hammer Candlestick?
The hammer is a bullish reversal candlestick pattern that forms after a sustained downtrend. Its name comes from its shape, which resembles a hammer with a long handle. The pattern suggests that sellers pushed price lower during the session, but buyers stepped in to push it back up by the close.
What the Pattern Looks Like
The hammer has three defining characteristics:
- A small real body at the top of the trading range
- A long lower shadow at least twice the length of the body
- Little to no upper shadow
The body can be either green (bullish) or red (bearish), though a green body is considered slightly stronger. The key feature is the long lower wick, showing rejection of lower prices.
What It Signals
The hammer signals that selling pressure is weakening. Even though sellers drove price down significantly during the session, buyers regained control and closed near the open. When this happens after a prolonged downtrend, it often marks a potential bottom.
| Signal Strength | Condition |
|---|---|
| Stronger | Long lower wick, green body, high volume |
| Weaker | Short lower wick, red body, low volume |
How to Trade It
- Confirm the downtrend. The hammer only matters after an established downtrend. In an uptrend, the same shape is called a "hanging man" and is bearish.
- Wait for confirmation. Enter only after a bullish candle closes above the hammer's high.
- Place your stop-loss below the hammer's low to protect against continued selling.
- Target recent resistance. Aim for the most recent swing high as your profit target.
Trading Example
Imagine a stock falls from $50 to $42 over two weeks. On day 15, price opens at $42.50, drops to $40 intraday, then closes back at $42.40 — forming a hammer. The next day, a strong green candle closes at $43.50. This confirmation gives traders a reason to enter long with a stop below $40.
Common Mistakes
- Trading the hammer before confirmation
- Using it in ranging markets where it lacks context
- Ignoring volume, which validates buyer interest
The hammer is one of the most popular reversal patterns for new traders because it's easy to spot, but it must be traded with patience and confirmation.
