### BOLLINGER BANDS RULES

5/7/ · There are three lines that compose Bollinger Bands: A simple moving average (middle band) and an upper and lower band. The upper and lower bands are typically 2 standard deviations +/- from a Likewise, if the average is shortened the number of standard deviations should be reduced; from 2 at 20 periods, to at 10 periods. Traditional Bollinger Bands are based upon a simple moving average. This is because a simple average is used in the standard deviation calculation and . 1/4/ · The Bollinger Bands Standard Deviation Calculation To calculate the standard deviation it is necessary to add the square root of the difference between the examined value and its moving average for each of the previous x periods taken into consideration, then divide this sum by the number of x periods evaluated and finally calculate the square root the result obtained from .

The bollinger bands is made up of three lines: Top band, middle band, and lower band. Using the standard bollinger band setting for this strategy, the lines are: Top line is 2 standard deviations from the middle line to the upside; The middle line is a 20 period moving average.

### Interpreting Bollinger Bands and How They Work

5/7/ · There are three lines that compose Bollinger Bands: A simple moving average (middle band) and an upper and lower band. The upper and lower bands are typically 2 standard deviations +/- from a 1/6/ · The default Bollinger Bands® formula consists of: A N-period moving average (MA) An upper band at K times and a N-period standard deviation above the moving average (MA + Kσ) A lower band at K times and a N-period standard deviation below the moving average (MA − Kσ)Author: Christian Reeve.
