The Piercing Line is a two-candle bullish reversal pattern. The first candle is a large bearish candle continuing the downtrend. The second opens at or below the first candle’s close, then rallies sharply to close above the midpoint of the first candle’s body — literally “piercing” into the prior session’s losses. The deeper the penetration above 50%, the stronger the signal.

How to Identify

• Appears at the bottom of a downtrend
• Candle 1: large bearish red candle with substantial body
• Candle 2: opens at or below candle 1’s close (gap-down open strengthens signal)
• Candle 2 closes above the 50% midpoint of candle 1’s body
• Penetration above 70% is considered a high-confidence signal
• Both candles should have meaningful body sizes

Market Psychology

The downtrend continues with a strong bearish session. The next day opens even lower — bears appear in full control. Then buyers step in aggressively, pushing price up through the entire prior session’s range and closing well above the midpoint. This dramatic intraday reversal signals that buyers have fundamentally shifted the balance of power and sellers can no longer sustain the move down.
