What Are Bollinger Bands?
Bollinger Bands is a technical indicator developed by John Bollinger in the 1980s that visualizes price volatility around a moving average. It's one of the most widely used indicators among FX traders.
Components of Bollinger Bands
| Component | Description | Meaning |
|---|---|---|
| Middle Band | 20-period Simple Moving Average (SMA) | Price trend direction |
| Upper Band | Middle Band + 2σ (standard deviation) | Upper price boundary |
| Lower Band | Middle Band - 2σ (standard deviation) | Lower price boundary |
Statistical Significance
With a 2σ setting, theoretically ~95.4% of prices fall within the bands. Breakouts beyond the bands can be considered "anomalies."
Calculation & Settings
Formula
- Middle Band = N-period SMA
- Upper Band = Middle Band + (K × N-period Standard Deviation)
- Lower Band = Middle Band - (K × N-period Standard Deviation)
Standard settings: N = 20, K = 2
Recommended Settings by Timeframe
| Timeframe | Period (N) | Std Dev (K) | Use Case |
|---|---|---|---|
| 1-5 min | 10-15 | 1.5-2.0 | Scalping |
| 15min-1hr | 20 | 2.0 | Day trading standard |
| 4hr-Daily | 20-25 | 2.0-2.5 | Swing trading |
| Weekly-Monthly | 20-50 | 2.0-3.0 | Long-term investing |
5 Practical Trading Strategies
Strategy 1: Squeeze Breakout
A squeeze occurs when band width becomes extremely narrow, indicating low volatility and often preceding major moves.
| Element | Details |
|---|---|
| Entry Condition | Band width at 6-month low → Band breakout |
| Direction | Enter in breakout direction |
| Stop Loss | Opposite band or middle band |
| Take Profit | When band width expands 1.5-2x |
Note: Win rates vary significantly based on market conditions. Past results do not guarantee future performance.
Strategy 2: Band Walk (Trend Following)
Band walk occurs when price moves along the upper or lower band, indicating a strong trend.
| Element | Details |
|---|---|
| Entry Condition | Price closes outside band → Add on middle band pullback |
| Trend Confirmation | Clear middle band slope |
| Stop Loss | Close below middle band |
| Take Profit | Band walk ends (approaches middle band) |
Strategy 3: Bollinger Bounce (Mean Reversion)
A counter-trend strategy targeting bounces from the upper/lower bands in ranging markets.
| Element | Details |
|---|---|
| Prerequisite | Stable band width (not squeezing) |
| Buy Entry | Touch lower band, confirm bounce |
| Sell Entry | Touch upper band, confirm rejection |
| Stop Loss | Close outside band |
| Take Profit | Middle band or opposite band |
Checkpoint: Mean reversion in trending markets is dangerous. Always confirm ranging conditions first.
Strategy 4: Double Bottom/Top
Combining Bollinger Bands with price patterns.
- Double Bottom Buy: First low breaks lower band, second low forms inside bands
- Double Top Sell: First high breaks upper band, second high forms inside bands
Strategy 5: %B Indicator
%B quantifies where price sits within the bands (0-1 scale).
| %B Value | Position | Signal |
|---|---|---|
| Above 1.0 | Above upper band | Overbought (consider sell) |
| 0.8 | Near upper band | Bullish market |
| 0.5 | Middle band | Neutral |
| 0.2 | Near lower band | Bearish market |
| Below 0.0 | Below lower band | Oversold (consider buy) |
Forex Applications
Currency Pair Characteristics

Combining with Other Indicators
RSI Combination
| Bollinger Band | RSI | Signal |
|---|---|---|
| Touch lower band | Below 30 | Strong buy signal |
| Touch upper band | Above 70 | Strong sell signal |
| Band breakout | RSI divergence | Trend reversal checkpoint |
MACD Combination
- Squeeze + MACD near zero line: Breakout preparation
- Band walk + MACD histogram expanding: Trend continuation
- Band touch + MACD cross: Entry timing
Common Mistakes & Solutions
Mistake 1: Counter-trending in Trends
| Problem | Solution |
|---|---|
| Immediate reversal on band touch | Assess trend via middle band slope |
| Unable to cut losses | Force stop on close outside band |
Mistake 2: Wrong Squeeze Direction
- Problem: Cannot predict breakout direction
- Solution: Enter after breakout confirmation (skip initial move)
Mistake 3: Overtrading
- Problem: Entering on every band touch
- Solution: Add confirmation from other indicators and market context
