What Are Bollinger Bands in Trading?
Bollinger Bands use three lines on price charts to display the volatility levels of a security.
The outer lines in Bollinger Bands extend from the central Simple Moving Average line according to specific standard deviation measurements.
The Core Components
- The 20-day simple moving average computes the standard average closing price based on the latest 20 trading sessions. The middle band serves as the principal indicator for tracking price activity in securities.
- The upper band results from adding a set number of standard deviations to the middle band. This band indicates potential resistance levels.
- To obtain the lower band the calculation requires subtracting multiple standard deviations from the central middle band. This band indicates potential support levels.
Bollinger Bands remain effective since their construction enables automatic adaptation to existing market conditions. During times of increased forex market volatility Bollinger Bands extend their range while they narrow down when market volatility declines.
Bollinger Bands provide traders with useful information as they maintain stable performance across different market conditions.
What Do Bollinger Bands Tell Traders?
Traders use a simple moving average (SMA) and standard deviations to build the Bollinger Bands indicator.
Here's a breakdown of the process:
- Choose a Period: By default Bollinger Bands utilize a 20-day SMA but traders have the flexibility to change this period to match their individual trading style and the specific asset under examination.
- Calculate the SMA: Determine the simple moving average by finding the average of closing prices throughout the selected timeframe.
- Calculate Standard Deviation: Calculate the standard deviation for the closing prices throughout the same time frame.
- Plot the Bands:
- Upper Band = SMA + (2 x Standard Deviation)
- Lower Band = SMA - (2 x Standard Deviation)
Trading platforms like MetaTrader 4 and MetaTrader 5 provided through BlueSuisse have built-in features to automatically determine and display these bands.
So, how do you interpret these bands?
Here are some key insights:
- Volatility: The expansion of the bands demonstrates increased volatility which implies that substantial price movements are likely to occur soon. When the bands become narrower they reveal decreased volatility which typically leads to a breakout.
- Overbought/Oversold Conditions: A move above the upper band could signal an overbought market condition which presents a chance to sell. A price touching or dropping below the lower band can indicate an oversold condition that presents a buying opportunity.
- Trend Direction: An uptrend causes prices to maintain positions above the middle band (SMA) whereas a downtrend forces prices to stay beneath it.

What Happens When Bollinger Bands Narrow?
The "squeeze" represents one of the most widely-used trading strategies with Bollinger Bands.
The market builds energy for major price movements during this period.
How to Trade the Squeeze
- Identify a Squeeze: Identify times when the bands converge tightly together and market volatility remains low.
- Prepare for a Breakout: Expand your trading strategy with long or short positions when you see band expansion during a breakout.
- Confirm the Breakout: Enter a trade only after the price moves through either the upper or lower band.
- Manage Risk: Protect your capital by setting stop-loss orders below or above the breakout point.
How Reliable Are Bollinger Bands?
Although Bollinger Bands serve as a useful analytical tool, traders must recognize their constraints. Bollinger Bands cannot predict future market movements with absolute certainty.
Traders gain valuable information about market volatility and potential price targets through Bollinger Bands to help them make educated trading decisions.
Limitations to Consider
- False Signals: The Bollinger Bands indicator often produces misleading signals when the market remains in lateral movement or during consolidation phases.
- Lagging Indicator: Bollinger Bands function as lagging indicators by showing price changes after they occur instead of forecasting upcoming price movements.
- Not a Standalone Tool: Bollinger Bands perform best when combined with additional technical indicators and analysis techniques.
Is Bollinger Bands a Leading Indicator?
Bollinger Bands work as lagging indicators because they rely on past price information to track price movements instead of forecasting them.
Traders benefit from Bollinger Bands because they reveal important data about market volatility and possible price targets which supports decision-making.
- Leading Indicators: Make future price movement predictions by analyzing different influencing factors.
- Lagging Indicators: Historical price data enables lagging indicators to validate trends and generate trading signals.
Leading indicators have the potential to offer early signals but they frequently generate inaccurate signals.
Lagging indicators deliver dependable signals yet they tend to indicate trends after they have already begun.
Best Indicators to Combine with Bollinger Bands
To make Bollinger Bands more useful traders frequently pair them with additional technical indicators.
- Relative Strength Index (RSI): Confirms overbought or oversold conditions.
- Moving Average Convergence Divergence (MACD): Identifies potential trend changes and momentum shifts.
- Stochastic Oscillator: The Stochastic Oscillator evaluates price momentum through a comparison of the closing price against its price range during a specific timeframe.
Bollinger Bands gain maximum effectiveness when integrated with additional technical indicators. When traders combine Bollinger Bands with additional indicators they achieve better signal filtering which enhances their trading strategy accuracy.
The RSI indicator helps traders confirm overbought conditions at the upper Bollinger Band level to reinforce selling positions.
Examples of Bollinger Bands
This section examines real-world applications of Bollinger Bands by studying a few practical trading examples.
Trend Following: When a market is in an uptrend traders can use Bollinger Bands to find entry points as prices retreat back to the middle band or SMA.
Reversal Trading: A trader operating in a ranging market can use Bollinger Bands to detect possible reversal zones when asset prices reach the upper or lower bands.
