What Is a Bollinger Band Squeeze?

A Bollinger Band Squeeze is a condition that occurs when the Bollinger Bands narrow due to decreased volatility. According to John Bollinger, periods of low volatility are often followed by periods of high volatility. Therefore, a volatility contraction or narrowing of the bands can foreshadow a significant advance or decline. Once the squeeze play is on, a subsequent band break signals the start of a new move. A new advance starts with a squeeze and subsequent break above the upper band. A new decline starts with a squeeze and subsequent break below the lower band.
