Bollinger Bands are a popular technical analysis tool used by traders to measure volatility and identify potential price reversals in financial markets. Developed by John Bollinger in the 1980s, these bands consist of a moving average line and two standard deviation lines plotted above and below it.
Bollinger Band %b is a powerful indicator derived from Bollinger Bands that helps traders determine the relationship between the current price and the bands. It measures where the price is in relation to the upper and lower bands and provides insights into the strength and direction of a trend.
To calculate Bollinger Band %b, you need to follow a step-by-step process. First, you need to calculate the Bollinger Bands by selecting an appropriate period, typically 20 days. The bands are calculated using the standard deviation of the price over the selected period.
Next, you calculate the %b value by taking the difference between the current price and the lower band, and dividing it by the difference between the upper and lower bands. This gives you a value ranging from 0 to 1, indicating where the price is in relation to the bands.
Understanding how to calculate Bollinger Band %b is essential for traders looking to incorporate this indicator into their trading strategy. By analyzing the %b values, traders can gain valuable insights into market conditions and make well-informed trading decisions.

What is Bollinger Band %b?
Bollinger Band %b is a technical indicator that is used in financial markets to measure the relative position of a price within the Bollinger Bands. The Bollinger Bands are a popular tool that is widely used by traders and analysts to analyze price volatility.
The %b indicator is based on the concept of standard deviation, which measures the dispersion of the price data around its mean. The Bollinger Bands consist of three lines: the middle band, which is a simple moving average (SMA); the upper band, which is the middle band plus a certain number of standard deviations; and the lower band, which is the middle band minus the same number of standard deviations.
The purpose of the Bollinger Band %b is to provide a visual representation of where the price is relative to the Bollinger Bands. It is calculated using the formula:
%b = (Price - Lower Band) / (Upper Band - Lower Band)
The resulting value ranges from 0 to 1, with values close to 0 indicating that the price is close to the lower band, and values close to 1 indicating that the price is close to the upper band. A value of 0.5 indicates that the price is at the middle band.
Traders and analysts use the Bollinger Band %b to identify potential overbought or oversold conditions, as well as to spot potential price reversals. When %b reaches extreme levels, it can signal that a price trend may be ending, and a reversal may be imminent.
Additionally, the Bollinger Band %b can be used in conjunction with other technical indicators and chart patterns to further validate trading signals and increase the probability of success. It is important to note that the Bollinger Band %b is just one tool among many, and should not be used in isolation to make trading decisions.
Understanding the Basics
The Bollinger Bands %b is a technical indicator that measures the position of the current price within the Bollinger Bands. To fully understand this indicator, it is important to have a clear understanding of the basics.
Bollinger Bands:
Bollinger Bands are a popular technical analysis tool created by John Bollinger. They consist of a simple moving average (SMA) in the middle, surrounded by an upper band and a lower band. The upper band is calculated by adding two standard deviations to the SMA, while the lower band is calculated by subtracting two standard deviations from the SMA. These bands provide a visual representation of the volatility and potential price levels of an asset.
%b:
The %b indicator is derived from the Bollinger Bands. It measures the relative position of the current price compared to the Bollinger Bands. The calculation of %b is as follows:
%b = (Current Price - Lower Band) / (Upper Band - Lower Band)
The %b value ranges from 0 to 1, with 0 indicating that the current price is at the lower band and 1 indicating that the current price is at the upper band.
Interpretation:
Understanding the %b indicator can help traders identify potential buying or selling opportunities. When the %b value is above 0.5, it suggests that the current price is closer to the upper band, indicating a potential overbought condition. Conversely, when the %b value is below 0.5, it suggests that the current price is closer to the lower band, indicating a potential oversold condition.
Traders can also look for divergences between the %b indicator and the price action. For example, if the price is making higher highs, but the %b value is making lower highs, it could indicate a bearish divergence and a potential reversal in price.
Conclusion:
Understanding the basics of Bollinger Bands %b is crucial for successful technical analysis. By considering the position of the current price within the Bollinger Bands, traders can gain insights into the potential overbought or oversold conditions of an asset. Additionally, by looking for divergences between the %b indicator and the price action, traders can identify potential reversals in price.
Step 1: Calculating the Middle Band
To calculate the Bollinger Bands %b, the first step is to calculate the middle band. The middle band is simply a Simple Moving Average (SMA) of the closing prices over a specified period of time.
Here's how you can calculate the middle band:
- Choose a period for the middle band. This could be any time frame that you prefer, such as 20 days, 50 days, or any other period that suits your trading strategy.
- Add up the closing prices for the chosen period.
- Divide the sum by the number of closing prices in the chosen period to get the average.
For example, let's say we want to calculate the middle band using a period of 20 days:
Step 1: Add up the closing prices for the last 20 days.
Step 2: Divide the sum by 20 to get the average.
Step 3: The result is the middle band.
Once you've calculated the middle band, you can move on to calculating the upper and lower bands, which will be discussed in the following steps.
Step 2: Calculating the Upper and Lower Bands
After calculating the moving average, the next step in calculating Bollinger Bands is to determine the upper and lower bands. These bands are used to identify potential overbought or oversold conditions in a security.
To calculate the upper band, add the standard deviation multiplied by the chosen factor (typically 2) to the moving average. This provides an indication of the upper boundary, or the level at which the security may be considered overbought.
To calculate the lower band, subtract the standard deviation multiplied by the chosen factor (typically 2) from the moving average. This provides an indication of the lower boundary, or the level at which the security may be considered oversold.
The upper and lower bands are typically represented on a chart as two lines that run parallel to the moving average. The distance between the upper and lower bands can be used as a measure of volatility. When the distance between the bands widens, it suggests that volatility is increasing, while a narrowing distance indicates decreasing volatility.
By comparing the current price of a security to its upper and lower bands, traders can assess whether the security is trading within a normal range or if it is potentially overbought or oversold.
It's important to note that the standard deviation used in calculating the upper and lower bands is based on historical prices. Therefore, as new data becomes available, the bands will adjust, reflecting changes in price volatility.
Calculating the upper and lower bands is a crucial step in using Bollinger Bands to analyze the price movement of a security. By understanding how to calculate these bands, traders can gain insight into potential price reversals and fluctuations in volatility.
