The sizes of a candlestick’s real body, wicks and tails can indicate a market’s volatility. Long wicks or tails in conjunction with a small real body signify a volatile market. When a candle has long wicks with a relatively small real body, it can signify a rejection of certain price levels. A candle with a small real body and with long wicks or tails on both sides denotes extreme volatility as well as market indecision. Learn more about candlestick patterns.
