A Hammer is a single Japanese candlestick pattern.

It is black or a white candlestick that consists of a small body near the high with a little or no upper shadow and a long lower shadow (or tail).

A Hammer candlestick is considered a bullish pattern when formed during a downtrend.

Hammer

In summary, the Hammer candlestick appears during a downtrend, displays a long lower shadow with a small real body at the top of the range.

The price may be developing a bottom and due for a reversal to the upside.

A Hammer candlestick pattern should meet the following criteria:

  • The candle must have either a very short upper shadow or no upper shadow at all.
  • The candle’s lower shadow must be quite tall (at least two times as height of the body).
  • The candle must form after a clear downtrend.
  • The candle’s body should be located at the upper end of the trading range.
  • The body’s color is unimportant (though a white candle hints at a more bullish bias).
  • The candle should be confirmed the following day, with the price trading above the Hammer’s body.

Don’t confuse the Hammer with the Hanging Man.

A Hanging Man looks identical but only forms at the end of an uptrend, while the Hammer forms after a downtrend.
