FAQ Based on “How to Trade Bollinger Bands”

Bollinger Bands are a widely-used tool in technical analysis, offering insights into market volatility and potential price movements. To help you better understand how to effectively use Bollinger Bands in your trading strategies, here are eight questions. Each question includes four answer options: one correct and three incorrect.

1 / 8

Question 1. What do Bollinger Bands primarily measure in technical analysis?

The level of market volatility and potential price extremes. Bollinger Bands measure market volatility and help identify potential price extremes.

The trading volume of an asset. Bollinger Bands do not measure trading volume; they measure volatility.

The trend direction of the market. While Bollinger Bands can help identify trends, their primary function is not to measure trend direction.

The average price of an asset over time. Bollinger Bands are based on moving averages but focus more on volatility than the average price.

2 / 8

Question 2. What is the default setting for the standard deviation in Bollinger Bands?

1 standard deviation. The default setting is not 1 standard deviation, though this can be used in specific strategies.

No standard deviation is used. Bollinger Bands rely on standard deviation to measure volatility.

3 standard deviations. While 3 standard deviations can be used for wider bands, the standard setting is 2.

2 standard deviations. The default setting for Bollinger Bands is 2 standard deviations from the moving average.

Question 3. How can traders use Bollinger Bands to identify overbought or oversold conditions?

By observing the middle band exclusively. The middle band represents a moving average and does not directly indicate overbought or oversold conditions.

By monitoring the width of the bands for extreme narrowing. Band narrowing, or a “squeeze,” signals low volatility, not necessarily overbought or oversold conditions.

By looking for price movements that consistently touch or move beyond the upper or lower bands. When the price touches or moves beyond the upper band, it may indicate overbought conditions; touching or moving below the lower band may indicate oversold conditions.

By comparing the Bollinger Bands to the Relative Strength Index (RSI). RSI can be used in conjunction with Bollinger Bands, but the bands themselves indicate overbought or oversold conditions based on price proximity to the bands.

Question 4. What does a Bollinger Band “squeeze” typically indicate?

A period of low volatility that may precede a significant price movement. A Bollinger Band “squeeze” occurs when the bands narrow, indicating low volatility that often precedes a breakout.

The end of a market trend. A squeeze does not necessarily signal the end of a trend, but it may indicate a potential trend change.

An increase in the accuracy of price predictions. While a squeeze can signal upcoming volatility, it does not guarantee accuracy in price predictions.

A market with consistent trading volume. A squeeze relates to volatility, not trading volume.

5 / 8

Question 5. How are the upper and lower Bollinger Bands calculated?

By adding and subtracting the trading volume from the moving average. Trading volume is not involved in the calculation of Bollinger Bands.

By calculating the percentage difference between opening and closing prices. Bollinger Bands do not use the percentage difference between opening and closing prices in their calculation.

By using the highest and lowest prices over a set period. The upper and lower bands are calculated using standard deviations, not simply the highest and lowest prices.

By adding and subtracting a standard deviation from the moving average. The upper band is calculated by adding, and the lower band by subtracting, a standard deviation from the moving average.

6 / 8

Question 6. What strategy can be used when the price consistently touches the lower Bollinger Band?

Ignore the signal as it has no trading significance. Touching the lower band can be significant, indicating potential buying opportunities.

It may be a signal to short the asset immediately. Consistently touching the lower band could indicate oversold conditions, not necessarily a short signal.

Hold the position until the price breaks the upper band. Waiting for a break of the upper band may not be the most effective strategy in this situation.

Consider entering a long position if other indicators confirm a potential reversal. When the price touches the lower band, it may signal an oversold condition, potentially offering a buying opportunity if confirmed by other indicators.

7 / 8

Question 7. Why might a trader use Double Bollinger Bands (DBB) in their strategy?

To simplify the trading strategy by reducing the number of variables. DBB adds complexity by introducing additional bands for analysis.

To get a clearer signal in highly volatile markets. Double Bollinger Bands provide additional levels (inner and outer bands) that can help clarify signals in volatile markets.

To eliminate the need for any other technical indicators. DBB enhances analysis but does not eliminate the need for other indicators.

To automatically identify the start of new trends. While DBB can help identify trends, it does not automatically signal the start of a new trend.

8 / 8

Question 8. What is a potential risk when using Bollinger Bands as a trading strategy?

They eliminate the need for stop-loss orders. Stop-loss orders are still essential for managing risk, even when using Bollinger Bands.

They automatically adjust to all types of assets. Bollinger Bands require setting adjustments depending on the asset and market conditions.

They guarantee profitable trades in all market conditions. Bollinger Bands are a tool for analysis and do not guarantee profits.

The bands may not adapt quickly enough to sudden market changes. Bollinger Bands, based on historical data, may not respond immediately to sharp market movements, posing a risk in volatile conditions.
