Whether you’re sharpening your strategies or starting from scratch, this guide equips you with actionable insights to confidently apply Bollinger Bands in your trading.
What Are Bollinger Bands?
Developed by John Bollinger in the 1980s, Bollinger Bands are a technical analysis tool that plots two standard deviations (positive and negative) away from a simple moving average (SMA) of a security’s price. The bands consist of:
- Middle Band: The SMA (default: 20-day).
- Upper/Lower Bands: Represent market volatility (default: 2 standard deviations).
When bands contract, volatility is low; when they expand, volatility is high.
How Bollinger Bands Work
The indicator’s brilliance lies in its dual ability to gauge:
- Market Volatility: Band width reflects volatility levels.
- Trend Direction: Prices "walking" the upper/lower bands signal strong trends.
👉 Pro Tip: Combine Bollinger Bands with RSI for stronger signals
Key Interpretations
- Squeeze: Narrow bands precede breakout moves.
- Breakout: Price crossing bands may indicate trend continuations (confirm with volume).
- Reversals: Rapid shifts between bands can signal trend reversals.
Setting Up Bollinger Bands on TradingView
