Bollinger Bands Calculation Example. Assume a 5 bar Bollinger band with 2 Deviations, and assume the last five closes were , , , , and Calculate the simple moving average: + + + + = / 5 = 4/16/ · Although our volume-weighted standard deviation bands are a significant improvement compared to the standard Bollinger Bands calculation, there is certainly room for improvement. For example, the heuristic 6 point model could be replaced with a better model for the intra-bar distribution of volume for different types of candles.

The next data point on the 21st day would cause the first day to fall off, providing a standard deviation of the asset’s price. 4/16/ · Although our volume-weighted standard deviation bands are a significant improvement compared to the standard Bollinger Bands calculation, there is certainly room for improvement. For example, the heuristic 6 point model could be replaced with a better model for the intra-bar distribution of volume for different types of candles.

### Introduction

Soon the Bollinger Bands had company, I created %b, an indicator that depicted where price was in relation to the bands, and then I added BandWidth to depict how wide the bands were as a function of the middle band. For many years that was the state of the art: Bollinger Bands, %b and BandWidth. Here are a couple of practical examples of the. Bollinger Bands Calculation Example. Assume a 5 bar Bollinger band with 2 Deviations, and assume the last five closes were , , , , and Calculate the simple moving average: + + + + = / 5 = Bollinger BandWidth is an indicator derived from Bollinger blogger.com his book, Bollinger on Bollinger Bands, John Bollinger refers to Bollinger BandWidth as one of two indicators that can be derived from Bollinger Bands (the other being %B).
