Reliability Rating: low/moderate
The Hammer, consists of a small body (either color) with a very long lower shadow. This pattern is typically found at the top or bottoms of trends. When the pattern occurs at the top of a up trend it is called a hangman (when it is found at the bottom of a down trend it is called a hammer).
For the most part, daily candlestick reversal patterns are quite subjective with the exception of the "long-legged shadows' Doji" and the "hangman and hammer" which are more commonly used and provide more significance to the trader
