If you are already trading with the Bollinger Bands indicator you will find that Bollinger Percent B indicator is just like the same. The only difference is that he Bollinger %B Indicator gives you a precise number by which you can identify the relationship between the price and the bands.
What is Bollinger %B Indicator?
It is a technical indicator that quantifies the price of a security with respect to the upper and lower limits of Bollinger Bands. We can have six relative relationships.
- The %B is at zero when the stock price is at the lower band.
- It is at 100 when the stock price is at the upper band.
- The %B is above 100 when the stock price goes above the upper band.
- It is below zero when the stock price goes below the lower band.
- The %B is above 50 when the stock price goes above the middle band.
- And it is below 50 when the stock price goes below the middle band.
Bollinger percent B uses the 20-day simple moving average (SMA) and 2 standard deviations (stdev.) as default parameters like the Bollinger bands. This indicator is available in Zerodha Kite both in its web version and the mobile app.

How to trade with the Bollinger Percent B Indicator?
#1 The simple rule
- 50 is an important level for this indicator.
- A buy position is created when the Bollinger %B indicator goes up from below the zero line and crosses 50 on the upside indicating price reversal.
- The buy position is closed when the Bollinger %b indicator tops above 100 line and starts coming down accompanied by a downward movement of price. Or one can close buy position if the stock price comes down with the indicator coming down from a position near 100 line.
#2 Bollinger %B Indicator Divergence
Just like the other oscillators, the %B also shows divergence with price. When the price is in a strong trend on the downside and makes a lower low but the %B can not make new low, it is a positive divergence. Watch the image below. After a positive divergence, there is a high chance that the price will bounce back and a trend reversal will happen. Traders can use a confirmation indicator like a trend line break to confirm the trend reversal.
Similarly, when the price makes a higher high the %B is unable to make a new high it is a negative divergence. There is a high chance that the uptrend will soon end and the price will start moving downwards.
#3 Advanced trading strategy
First, look for extreme price action. Suppose we found %B above 100 or below 0 in any stock. That means the price is above the upper Bollinger Bands or below the lower Bollinger Bands. Now, this is an extreme case and extreme price action can not continue for long. So now wait for a pullback. If the %B indicator pulls back to 50 or to the other extreme end enter into a trade.
The buy setup
- The %B must hit +100 and cross above it.
- Wait for a pullback of the %B to 50 below or the price touching the lower Bollinger Bands.
- Enter a buy trade with a suitable stop loss and a target.
The sell setup
- The %B must hit 0 and cross below it.
- Now, wait for a pullback of the %B to 50 or above or the price touching the upper Bollinger Bands.
- Enter a short sell trade with a suitable stop loss and a proper target.
