What Are Bollinger Bands?
Bollinger Bands are a technical analysis tool created by John Bollinger. They help traders understand whether a price is high or low compared to its recent history.
Each Bollinger Band has 3 parts:
- Middle Band: A 20-period Simple Moving Average (SMA)
- Upper Band: SMA + (2 × standard deviation)
- Lower Band: SMA – (2 × standard deviation)
These bands expand and contract depending on the volatility of the market.
How Do Bollinger Bands Work?
- When the bands are wide, it means the market is highly volatile
- When the bands are tight, it means the market is calm
- Price touching the upper band often means overbought
- Price touching the lower band can mean oversold
But never trade based on this alone — combine with other indicators like RSI or MACD.
Best Settings for Bollinger Bands
For most markets, the default settings work great:
- Period: 20
- Deviation: 2
But you can adjust:
- For short-term (5 min charts): Try Period 10 and Deviation 1.5
- For long-term (daily charts): Stick to Period 20 and Deviation 2
Try testing with a paper trading account first.
Simple Bollinger Band Trading Strategies
1. Bollinger Bounce Strategy
- Works best in a sideways market
- Buy near lower band → Sell near upper band
2. Bollinger Squeeze Strategy
- When bands are super tight, a breakout is coming
- Watch for price to break above or below the band with volume
3. Combine with RSI
- RSI below 30 + price at lower band = Possible buy signal
- RSI above 70 + price at upper band = Possible sell signal
