Hammer Candlesticks Patterns Explained & Reliability Tested

Testing the Hammer Candlestick with 2,219 Trades!

The Hammer candlestick is a popular chart pattern that suggests bullish sentiment after a day of trading volatility. The Hammer is easily recognizable and occurs frequently on charts, but is it profitable?

Is the Hammer pattern reliable or accurate? To discover the facts, I backtested 2,219 Hammer trades on 549 years of trading data spanning bull and bear markets. Our data-based evidence is shocking. Get ready to embark on a data-driven adventure into Hammer patterns!


  • The Hammer is an unreliable and risky pattern with a low accuracy rate of 52.1%, which is hardly better than flipping a coin.
  • The Hammer pattern does not predict market direction with any certainty whatsoever.
  • A small profit per trade of 0.18% and a low Sharpe ratio of -0.05 suggest trading the Hammer is highly risky.
  • Our evidence suggests that the Hammer pattern should not be used in any trading strategy.

What Is a Hammer Candle?

A Hammer candle is a popular pattern in chart technical analysis. It is characterized by a small body and a long lower wick, resembling a hammer, hence its name. The hammer candle typically appears at the end of a downtrend, indicating a potential reversal in price movement.

Traders interpret this pattern as a signal of bullish sentiment, where the market is attempting to reject lower prices, evidenced by the long lower wick. However, the confirmation of a trend reversal is usually obtained from the candles succeeding the hammer candle.

What Does a Hammer Candle Mean?

When a Hammer candle occurs, it represents a potential turning point in the market. Traders see it as a signal that the market could soon be reversing from a downtrend to an uptrend. This candlestick pattern is supposedly an indication that the selling pressure at the opening of the trading period has been overcome by buying pressure, pushing the price back up and closing near the opening level.

Traders believe this signifies buyers gaining momentum against sellers, heralding a potential bullish trend. But are they correct in their assumption? Our decades of research suggest this theory is completely wrong.

Types of Hammer Candle

There are two types of Hammer candles: the Hammer and the Inverted Hammer. While the Hammer is a low probability trade and one of the poorest performing candlestick patterns we have tested, the Inverted Hammer is the opposite. The Inverted Hammer looks like an upside-down Hammer and is the most profitable of all candle patterns.

The Inverted Hammer typically manifests at the bottom of a downtrend, hinting at a potential shift in the price trajectory. It signals a bullish sentiment, denoting that the market is trying to push prices higher, as indicated by the extended upper wick. However, the sellers regain control by the close of the trading period, pushing the price down to close near the opening level, thus creating a small body at the bottom.

Hammer Candle Explained

A Hammer Candle occurs when the opening, high, and close prices are roughly the same, and there’s a significantly lower wick at least twice the size of the small body. The candle’s body can be either bearish (red) or bullish (green), but the bullish variant is considered more significant.

In the context of a downtrend, the market opens, and sellers push the prices down significantly, which is reflected by the long lower wick. However, buyers step in by the end of the trading period and push the price back up to near where it opened, creating the small body at the top of the candle.

The Hammer Candlestick Explained: The Hammer Candle represents a battle between buyers and sellers where the sellers initially have the upper hand, driving prices down. However, the buyers eventually step in and rally, driving the price back up to the opening level.

Candle Pattern Recognition with TrendSpider

The Hammer candle supposedly indicates bullish sentiment and a potential trend reversal, but our testing proves this theory wrong.

The Psychology of the Hammer

The psychology behind the Hammer pattern is that sellers initially have the upper hand, driving prices down. However, the buyers eventually step in and rally, driving the price back up to the opening level. This shift in momentum indicates that the selling pressure is being exhausted, and a potential reversal might be on the horizon. The Hammer Candle, therefore, represents a tug-of-war that ends with the buyers gaining ground, potentially signaling the beginning of a bullish trend.

But is the Hammer really a bullish pattern? Our research goes against popular opinion based on data.

Is a Hammer a Bullish Reversal Pattern?

No, according to our testing, the Hammer is not a bullish reversal pattern. The results from 2,219 tested trades show that the Hammer does not conclusively indicate any future price move. The Hammer’s low 52.1% accuracy rate means it fails to predict market direction 48.9% of the time.

As you can see in the chart above, the Hammers occur during uptrends and downtrends, but they rarely signal a price reversal. This unreliability is reflected in our testing, which indicates that Hammers are not indicative of any future price move.

How to Trade a Hammer Candle?

Trading Hammers is not recommended as they do not offer reliable predictive information. While the Hammer signifies a bullish end to the trading day, this does not guarantee the next day will be positive. However, there are some cases where this pattern with a very long body can be traded for profit after a strong downtrend. But I advise checking this hypothesis with your own backtesting before trading this pattern.

Our backtesting data (see the screenshot below) shows a winning and losing trade on Apple Inc. The winner made a 9.41% profit in 10 days. The losing trade lost -4.15%. In fact, trading Apple stock for over 20 years, the Hammer worked well with a 58% win rate and an average return of 1.01% per trade.

But is this because the Hammer was predictive or because Apple Inc. is in a continual uptrend? The evidence across all stocks suggests the latter.

When engaging in Hammer trading, it is crucial to employ confirmations through reliable candle patterns, such as Inverted Hammer or Bearish Marubozu. Additionally, reliable indicators like the Relative Strength Index (RSI), Rate of Change (ROC), or Volume can aid in assessing the likelihood of a trend reversal or continuation. By optimizing your approach with these techniques, you can enhance both the quality and effectiveness of your trading strategy.

Hammer Candle Test Results

After conducting 2,219 trades on 575 years of data, we confirm the Hammer profit per trade to be 0.18%. A 0.18% win rate means that trading a Hammer long will net you an average of 0.18% profit per trade if you sell after ten days. Conversely, short-selling a Hammer, you should expect to lose 0.18% per trade.

The percentage of Hammer winning trades was 52.1% versus 47.9% losing trades, slightly lower than the 55.8% average performance across all candlestick types. The Max Drawdown was -36.2%, versus the stock’s drawdown of -58.2%, which shows less volatility than a buy-and-hold strategy.

The average winning trade was 3.6% over ten days, but the average losing trade was also -3.6%; this represents an incredibly thin profit margin that should not be traded. The reward-to-risk ratio is 1.01, significantly less than many of our backtested and proven chart patterns.

The Sharpe ratio, a measure of risk, is -0.05; a good investment should be higher than 1.0; thus, the Hammer is considered the most risky candle trade of all. The Sortino ratio of 0.25 is also incredibly poor as the target should be 2, so again, it is a very risky trade.

Hammer Candle Test Results Summary

Ultimately, for every long trade you make after a Hammer appears on a daily stock chart, on average, you should make 0.18% after holding for ten days. This terrible result makes the Hammer one of the worst candlestick pattern trades.

Conversely, the best candlestick for trading is the Inverted Hammer, with a profit per trade of 0.97%, nearly 5 times better than the Hammer candle.

Does the Hammer Candle Work?

No, the Hammer does not work in trading, producing a 52.1% success rate. The average profit per trade for a Hammer is small, only 0.18% after ten days. If you sell it short, it will average a 0.18% loss. Such small wins will be erased by slippage and trading costs.

Is a Hammer Candle Accurate?

No, a Hammer is one of the most inaccurate patterns to trade; it results in 52.1% of trades winning and 47.9% of trades losing, plus the average winning trade is 3.6% and losing trade is -3.6%. Using a Hammer is no better than flipping a coin.

Can the Hammer Candle be used for Buy and Sell Signals?

No, our data shows the Hammer should never be used for buy and sell signals. Its accuracy is incredibly poor and should not be relied upon. In 2,219 trades, the Hammer buy signal was only 52.1% accurate and yielded just 0.18% profit.

Is a Hammer Candle Bullish or Bearish?

The evidence of 2,219 trades suggests that the Hammer is not significantly bearish or bullish. Our test results show that a Hammer is 52.1% bullish and 47.9% bearish. In any ten days following a Hammer, the market moved up 52% and down 48%; this move is due to the market’s positive bias, not due to any predictive quality of the Hammer.

Is a Hammer Candle Reliable?

According to 2,219 tested trades, a Hammer is extremely unreliable and unprofitable. It has a low % accuracy rate of 52.1%, resulting in a razor-thin 0.18% profit per trade. Factoring in a very low Sharpe ratio of -0.05 indicates this is an unreliable and risky trade.

Therefore, I would not recommend using the Hammer pattern for trading.

Inverted Hammer: 1,702 Trades Prove Its The Best Candle Pattern


In conclusion, the Hammer is one of the most unreliable and risky trades in technical analysis. It has a low accuracy of 52.1%, resulting in a small profit per trade of 0.18%. It does not conclusively demonstrate any predictive qualities.

The Hammer is unprofitable for long trades lasting ten days and is not recommended for trading due to the narrow margins. Additionally, slippage and fees will wipe out any profits gained.
