A bullish trading pattern formed when a security trades significantly lower than its opening but ends up closing near the original opening price. This creates a candlestick little to no upper shadow and a long lower shadow (typically at least double the length of the real body). If the price starts moving up following the hammer (known as “confirmation”), hammer candlesticks indicate a reversal to the upside.
