Counterattack Lines are a two-candle candlestick reversal pattern where the second candle completely negates the direction of the first candle by closing at exactly (or very near) the same closing price — but from the opposite direction. A Bullish Counterattack occurs during a downtrend: a strong bearish candle is followed by a gap-down open on the second candle, but buyers push prices sharply higher during the session so the second candle closes at or near the same level as the first candle's close — suggesting that selling pressure has been absorbed and buyers are gaining control. A Bearish Counterattack occurs during an uptrend: a bullish candle is followed by a gap-up open, but sellers push prices back down to close at or near the prior session's close — signalling that buying momentum is faltering. Counterattack Lines are less commonly discussed than similar patterns like the Piercing Pattern or Dark Cloud Cover, but they carry a similar reversal implication. In Indian equity markets, they are most significant when accompanied by high volume and appearing at technically important price levels.
