BOLL
The Bollinger Bands (BOLL) indicator is a popular technical analysis tool used in cryptocurrency trading. It consists of a simple moving average (usually 20 periods) and two standard deviations plotted above and below the moving average.
These bands dynamically adjust based on volatility; when the price is more volatile, the bands widen, and when it's less volatile, they contract. Traders often use Bollinger Bands to identify potential overbought or oversold conditions and to gauge the price's volatility relative to recent levels. When the price reaches the upper band, it might indicate that the asset is overbought, while reaching the lower band could suggest oversold conditions.
