The Bollinger Bands indicator is a popular tool used in technical analysis to gauge market volatility and identify potential price trends. It consists of a middle band, typically a simple moving average, and two outer bands that represent standard deviations above and below this average. When the bands contract, it signals low volatility, often preceding a significant price movement, while expanding bands indicate increased volatility. Traders use Bollinger Bands to detect overbought or oversold conditions, as price movements near the upper or lower bands may suggest trend reversals or continuations.
