Shadow

A candlestick shadow, or wick, which may be seen on a candlestick chart, is a vertical line that appear above and/or below the body of the candlestick. These shadows essentially represent the highest (upper shadow) and lowest (lower shadow) prices at which a securities has traded over a certain period of time. The candlestick's shadow can be compared to its wide part, which is referred to as the body of the candle. The longer is the shadow, the stronger is the reversal following that price action, once price breaks out of the consolidation period, either to the upside or downside depending on market conditions for that specific security.
