The upper band is the moving average plus a standard deviation, and the lower band is the moving average less the standard deviation. To put this into context, the mean we are talking about in Bollinger Bands is the 20-day simple moving average. Imagine a data set of 20 prices, calculate the mean, calculate the difference between each price data with the mean, square it, sum it up and square root it. That will give the standard deviation figure over the past 20 days. Bollinger Bands are a volatility channel technical analysis tool that plots a middle line between an upper and lower line that plot X standard deviations from an average price .

Such techniques usually require the sample to be independent and identically distributed, which is not the case for a time series like security prices. When using trading bands, it is the action of the price as it nears the edges of the band that should be of particular interest to us.
