Hammer candlestick pattern

There are few patterns where the shadows play a major role than the body. One of these are hammers, which is comprised of one single candle. It is called so because the Japanese will say the market is trying to hammer out a base. A hammer pictorially displays that the market opened near its high, sold off during the session, then rallied sharply to close well above the extreme low. Note it can close slightly above or below the open price, in both cases it would fulfill the criteria. Because of this strong demand at the bottom, it is considered a bottom reversal signal.
