Bollinger Bands are a powerful yet underutilized indicator in short-term trading. Developed by John Bollinger, they consist of three key components:
- A simple moving average (SMA)
- Upper Bollinger Band: SMA + (2 ร standard deviation)
- Lower Bollinger Band: SMA โ (2 ร standard deviation)
These bands dynamically adjust to market volatility, encapsulating approximately 99% of price movements in sideways markets.
How Bollinger Bands Work
Key Characteristics:
- Sideways Markets: Prices oscillate between the upper and lower bands, making them ideal for "fading" strategies (selling near the upper band, buying near the lower band).
- Trending Markets: Prices persistently touch one band (upper in uptrends, lower in downtrends), signaling trend strength.

Optimal Settings for Short-Term Trading
For intraday or swing trading, John Bollinger recommends:
- SMA Period: 9โ12 bars (adjust based on asset volatility).
- Standard Deviation: 2.
Example: A 12-bar SMA with 2 standard deviations balances responsiveness and reliability.
| Market Condition | Bollinger Band Signal | Action |
|------------------|------------------------|--------|
| Uptrend | Upper band points up; prices touch upper band | Look for long entries |
| Downtrend | Lower band points down; prices touch lower band | Look for short entries |
| Sideways | Bands flatten; prices oscillate between bands | Fade the extremes |
Identifying Trend Reversals
Warning Signs:
- Prices stop touching the trending band.
- Band begins to flatten.
- Confirmation: Exit trend-following positions when bands flatten entirely.
Pro Tip: Combine Bollinger Bands with MACD or RSI to confirm trends and filter false signals.
Practical Trading Strategies
1. Trend-Following Entry
- Condition: Upper band points up + prices touch upper band (uptrend).
- Action: Enter long with a stop-loss below recent swing low.
2. Sideways Fade
- Condition: Prices hit upper/lower band in a rangebound market.
- Action: Fade with tight stops (e.g., 1ร ATR).
