Key Points
- Bollinger Bands are a popular technical analysis tool developed by John Bollinger in the 1980s.
They consist of:
- A Simple Moving Average (SMA) as the centerline.
- Two standard deviation bands forming a volatility channel.
- Prices typically remain within the bands, which expand with higher volatility and contract during calmer markets.
- Breaches of the upper/lower bands may signal overbought/oversold conditions, hinting at potential reversals.
Understanding Bollinger Bands
What Are Bollinger Bands?
Bollinger Bands visually represent market volatility and price levels. Key components include:
- Middle Band (SMA): 20-period moving average (default setting).
- Upper/Lower Bands: Calculated as ±2 standard deviations from the SMA.
👉 How they work:
- Expanding bands = Rising volatility (e.g., during breakouts).
- Contracting bands ("squeeze") = Low volatility, often preceding significant price moves.
Interpreting Bollinger Bands
- Upper band touch: Potential overbought signal (consider selling).
- Lower band touch: Potential oversold signal (consider buying).
- Bandwidth changes: Indicate shifts in market volatility.
Effective Bollinger Bands Strategies
1. Bollinger Bands + Moving Average (BBMA Strategy)
Steps:
- Add a 50 EMA and Bollinger Bands to your chart.
- Buy signal: 50 EMA crosses above the middle band.
- Sell signal: 50 EMA crosses below the middle band.
- Exit trades on opposite crossovers.
2. Bollinger Bands + RSI
Steps:
- Wait for RSI to reach overbought (>70) or oversold (<30).
- Confirm price is outside Bollinger Bands.
- Enter when price re-crosses the middle band.
Example:
- Gold chart shows RSI oversold + price below lower band → buy signal when price reclaims middle band.
Common Mistakes to Avoid
- Misinterpreting band touches: Not every touch signals a reversal—context matters!
- Ignoring trends: Bands work best with trend analysis (e.g., uptrends may "walk" the upper band).
- Over-reliance: Combine with indicators like MACD or volume for confirmation.
Bollinger Bands Trade Example

👉 Pro Tip: Always backtest strategies to validate performance.
