A black candlestick is formed in case of a downtrend and follows the market’s movement. A gap down, which occurs when next candlestick is forming, supports a downward movement. At the same time, the price is rising, and the white candlestick closes far above the black one.
The white candlestick determines a closing price slightly higher than the midpoint of the price range of the previous black candlestick. It is a sign that the price has reached the bottom of a downtrend.
The second white candlestick must close slightly higher than a midpoint of the price range of the previous black candlestick. Otherwise, it is better to wait for a signal that confirms a bullish trend.
When analyzing the Piercing Line pattern, traders should look for the Paper Umbrella or Hammer lines which indicate a trend reversal. Sometimes, one candle penetrates into the body of another. In this case, the first one maintains the bullish character.
The piercing candle is also similar to the Thrusting Line continuation pattern as well as to such candle patterns as In Neck Line and On Neck Line.
