I just realized that many people do not truly understand the hammer candlestick, one of the most popular candlestick patterns in technical analysis. Not only used in crypto, but it is also widely applied in stock trading, indices, bonds, or Forex.

The advantage of the hammer is that it helps you identify potential reversal points. Depending on the timeframe and market context, this pattern can signal a bullish reversal after a downtrend or a bearish reversal after an uptrend. When combined with other indicators, it becomes a powerful tool for finding entry points.

Basically, the hammer looks like a candlestick with a small body and a long lower shadow, which must be at least twice as long as the body. This long shadow indicates that sellers pushed the price down, but then buyers drove the price back up above the opening price.

There are two types of bullish hammer candlesticks: the regular hammer (closing price higher than opening price, green candle) and the inverted hammer (opening price lower than closing price, with a long upper shadow). Both appear after a downtrend and signal a potential bullish reversal.

Conversely, bearish hammer candlesticks have two forms: the hanging man (when the opening price exceeds the closing price, creating a red candle) and the shooting star (when the opening price is higher than the closing price, with a long upper shadow). They appear after an uptrend and suggest a potential bearish reversal.

In practice, to effectively use the hammer, you need to consider its position relative to the preceding and following candles. Market context is very important—an reversal pattern can be confirmed or invalidated depending on the specific situation.

I see its advantage as being suitable for any market and applicable across multiple timeframes, from swing trading to day trading. However, its downside is that it heavily depends on context and is not always reliable. Therefore, the hammer should not be used alone but combined with other tools such as moving averages, RSI, MACD, or Fibonacci retracements.

Another pattern often confused with the hammer is the Doji. Doji looks like a hammer but has no body—it opens and closes at the same price. While the hammer indicates a potential reversal, the Doji usually suggests market indecision or trend continuation.

In summary, although the hammer is a useful tool for identifying reversal points, it is not a guaranteed buy or sell signal by itself. Always combine it with other indicators, manage risk properly, and use stop-loss orders to protect your capital.
