About the Author
John Bollinger is a respected authority in the world of financial markets and technical analysis. With over three decades of experience, he developed Bollinger Bands in the 1980s as a dynamic tool to measure price volatility and identify potential price movements. His expertise extends beyond indicator creation—he is also the president of Bollinger Capital Management, where he applies his methodologies to real-world portfolio management for both institutional and individual investors.
Bollinger’s contributions to trading education have made him a sought-after speaker and author. His work emphasizes a disciplined, analytical approach to trading, blending technical tools with sound risk management principles.
What Are Bollinger Bands?
Bollinger Bands are a volatility-based technical indicator consisting of three lines plotted on a price chart:
- A middle band, typically a 20-period simple moving average (SMA)
- An upper band, set two standard deviations above the middle band
- A lower band, set two standard deviations below the middle band
These bands expand and contract based on market volatility—widening during periods of high volatility and narrowing during calm markets. This dynamic nature makes them highly effective for identifying potential breakouts, reversals, and overbought or oversold conditions.

Core Concepts from the Book
John Bollinger emphasizes that his bands are not standalone signals but part of a broader analytical system. Here are the key ideas distilled from the book:
1. Measuring Market Volatility
The primary function of Bollinger Bands is to visualize volatility. When bands widen, it indicates increasing market activity; when they narrow (a "squeeze"), it often precedes a sharp price movement. Traders can use this information to anticipate breakouts.
2. Identifying Overbought and Oversold Levels
When price touches or moves outside the upper band, it may suggest overbought conditions. Conversely, when price approaches or falls below the lower band, it could signal oversold territory. However, these levels aren’t automatic reversal signals—they must be confirmed with other tools.
3. Trend Identification and Confirmation
Bollinger Bands help identify trend strength. In an uptrend, prices often ride along the upper band; in a downtrend, they hug the lower band. A reversal may occur when price breaks through the opposite band or fails to sustain momentum after touching one.
4. The “Bollinger Squeeze”
One of the most powerful setups described in the book is the squeeze, which occurs when the bands contract tightly around the moving average. This low-volatility phase often precedes high-momentum moves. Traders watch for a breakout candle closing outside the bands to confirm direction.
5. Combining with Other Indicators
Bollinger advises pairing his bands with complementary tools like RSI (Relative Strength Index), MACD, or volume indicators. For example, an RSI divergence near the upper band can strengthen a bearish reversal signal.
6. Customization for Different Markets
Traders can adjust the period (e.g., 10, 20, 50) and standard deviation (e.g., 1.5, 2, 2.5) to suit different assets and timeframes. Short-term traders might use tighter settings for forex, while long-term investors may prefer wider parameters for stocks.
7. Risk Management Integration
Setting stop-loss orders just beyond the bands helps manage downside risk. If price breaks out but quickly reverses back inside, it may indicate a false breakout—another reason to use tight risk controls.
8. Support and Resistance Dynamics
The bands often act as dynamic support and resistance levels. In trending markets, prices bounce off these levels repeatedly, offering high-probability entry points.
Practical Applications in Trading
Applying Bollinger Bands effectively requires more than just chart placement—it demands context and confirmation.
Example: EUR/USD Trade Setup
Imagine observing EUR/USD in an uptrend. Price pulls back to touch the lower Bollinger Band while RSI shows oversold conditions. Volume increases on the rebound, and price closes back inside the bands. This confluence suggests a potential long entry with a stop loss placed below the recent swing low.
This kind of multi-factor analysis aligns perfectly with Bollinger’s philosophy: never rely on a single signal.

Frequently Asked Questions (FAQ)
Q: Can Bollinger Bands predict future price movements?
A: No—Bollinger Bands are based on historical data and reflect past volatility. They help assess current conditions and potential opportunities but do not guarantee future outcomes.
Q: Are Bollinger Bands suitable for all timeframes?
A: Yes. They work across intraday charts (like 5-minute or hourly) to daily, weekly, and even monthly timeframes. Adjusting parameters ensures relevance across different trading styles.
Q: Should I trade every time price touches a band?
A: Not necessarily. Touching a band alone isn’t enough. Look for confirmation via candlestick patterns, momentum indicators, or volume spikes before entering trades.
Q: How do I avoid false signals during strong trends?
A: In strong trends, price can remain near or outside a band for extended periods. Avoid counter-trend trades unless there’s clear reversal evidence (e.g., bearish engulfing pattern + RSI divergence).
Q: Can Bollinger Bands be used in crypto trading?
A: Absolutely. Due to crypto’s high volatility, Bollinger Bands are especially useful for spotting squeezes and breakout opportunities in assets like Bitcoin or Ethereum.
Q: What’s the best companion indicator for Bollinger Bands?
A: RSI and MACD are popular choices. RSI helps identify overbought/oversold zones, while MACD confirms trend direction and momentum shifts.
