A hammer candlestick is a single candlestick pattern in technical analysis that signals a potential bullish reversal in a security’s price trend. Recognized by its long lower shadow, a small real body at the top, and minimal upper shadow, the hammer indicates that sellers drove prices lower during the trading period, but buyers managed to push prices back up near the opening price by the close.
Definition and Characteristics
Visual Characteristics
A hammer candlestick has:
- Long Lower Shadow: The lower shadow should be at least two times the length of the real body.
- Small Real Body: Positioned at the top end of the trading range, showing little difference between the opening and closing prices.
- Minimal or Absent Upper Shadow: Often non-existent or very short.
Basic Formulation in Technical Analysis
The hammer candlestick typically appears at the bottom of downtrends and indicates a potential reversal. Its appearance suggests that sellers were initially in control, pushing the price to a new low during the session. However, the strong closing price indicates that buyers overcame the selling pressure, thereby potentially reversing the downtrend.
Example
Consider a stock that has been in a downtrend. On a particular day, the stock opens at $50, falls to an intraday low of $40 but then rallies to close at $49, forming a hammer candlestick. This pattern suggests the downtrend could be reversing.
Historical Context
The concept of candlestick patterns originates from Japanese rice traders in the 18th century. These traders used similar patterns to predict future price movements. The hammer pattern remains widely acclaimed in modern-day technical analysis.
Applicability
Hammer candlesticks are used across various financial markets including stocks, forex, commodities, and cryptocurrencies. Traders rely on this pattern to make informed decisions about potential market reversals.
