How does the Bollinger Band operate?
Bollinger Bands are a technical analysis tool to assess market volatility and identify potential trading opportunities. Developed by John Bollinger, they consist of three lines plotted on a price chart:
1. The Middle Band: A simple moving average (SMA), typically set to 20 periods.
2. The Upper Band: Positioned two standard deviations above the middle band.
3. The Lower Band: Positioned two standard deviations below the middle band.
The bands expand and contract based on market volatility. When volatility increases, the bands widen; when it decreases, they contract. This dynamic nature helps traders gauge the strength and direction of price movements.
Key functions of Bollinger Bands include:
Identifying Overbought and Oversold Conditions: When prices approach the upper band, they may be overbought, signalling potential selling opportunities. Conversely, prices may be oversold when they approach the lower band, indicating potential buying opportunities.
Monitoring Breakouts: Prices breaking outside the bands suggest strong momentum, often followed by significant moves.
Trend Reversals: The squeeze, or a narrowing of bands, indicates low volatility and often precedes breakout phases.
While Bollinger Bands are versatile, they are most effective when used with complementary tools like Relative Strength Index (RSI) or Moving Average Convergence Divergence (MACD) for confirmation.
