Whiskers, within the context of trading charts, refer to the lines that extend from the colored bar in a candlestick chart which show the entire low-high range of a trading pair within a specific time frame. Whiskers are also called “wicks” or “shadows”.
Usually, each candlestick segment of a chart will have a solid box (also referred to as the candlestick body) that had been formed in light of the opening and closing prices. These come with two whiskers that can be seen extending above and below the core box. These whiskers actually represent the highest and lowest point record within the specified timeframe.
When the box and whiskers are ether red or black, the price of the underlying asset had fallen during the timeframe. Should the box and the whiskers are both green, the price had risen.
