BORING DEFINITION
Bollinger Bands are a type of technical analysis tool used to measure market volatility. They consist of three lines: a simple moving average in the middle and two standard deviation lines above and below it, forming a band that expands and contracts with market fluctuations. This tool helps traders identify overbought or oversold conditions in the market.
How Does Bollinger Bands Work?
Bollinger Bands are calculated using a 20-day simple moving average as the middle line and adding/subtracting two standard deviations for the upper and lower bands respectively. As market volatility increases or decreases, these bands widen or narrow. Traders interpret crossings of price through these bands as potential buy or sell signals.
Why it matters: Understanding Bollinger Bands is crucial for traders who want to gauge market volatility and make informed decisions based on potential overbought or oversold conditions.
