The middle band is a normal moving average. In the following formula, "n" is the number of time periods in the moving average (e.g., 20 days). The upper band is the same as the middle band, but it is shifted up by the number of standard deviations (e.g., two deviations).
Assume a 5 bar Bollinger band with 2 Deviations, and assume the last five closes were 25.5, 26.75, 27.0, 26.5, and 27.25. Calculate the simple moving average: 25.5 + 26.75 + 27.0 + 26.5 + 27.25 = 133.0. 133.0 / 5 = 26.6. Next, for each bar, subtract 26.6 from the close and square this value: For the upper band, add the standard deviation to the moving average. For the lower band, subtract the standard deviation from the moving average. Typical values used: Short term: 10 day moving average, bands at 1.5 standard deviations. (1.5 times the standard dev. +/- the SMA) Medium term: 20 day moving average, bands at 2 standard deviations. https://www.forexboat.com/ Get Your Free Membership Now!
