The first stage in calculating Bollinger Bands is to take a simple moving average. The standard deviation is a measure of volatility, and it increases when the price moves away from the average.
The standard deviation is then multiplied by a factor typically 2. We calculate the upper band by adding the standard deviation multiplied by the factor to the moving average. We calculate the lower band by subtracting the standard deviation multiplied by the factor from the moving average. This means that you can apply them to any market and timeframe without needing to adjust the parameters. You can learn how to backtest your trading strategies using a Tradinformed Backtest Model.
The models are built using Excel and you can use them to test on any timeframe and market. See the latest models in the Tradinformed Shop.

Just like in case of the Envelopes, the interpretation of the Bollinger Bands is based on the fact that the prices tend to remain in between the top and the bottom line of the bands. A distinctive feature of the Bollinger Band indicator is its variable width due to the volatility of prices.
In periods of considerable price changes i. During standstill periods, or the periods of low volatility the band contracts keeping the prices within their limits. Bollinger bands are formed by three lines. The middle line ML is a usual Moving Average. The top line TL is the same as the middle line a certain number of standard deviations D. The bottom line BL is the middle line shifted down by the same number of standard deviations.
It is recommended to use period Simple Moving Average as the middle line, and plot top and bottom lines two standard deviations away from it. Besides, moving averages of less than 10 periods are of little effect. The full description of the Bollinger Bands is available in the Technical analysis:
The top line TL is the same as the middle line shifted up by a certain number of standard deviations D. The bands encapsulate the price movement of a stock.
