Bollinger Bands are displayed as three bands. 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). 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 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 The Bollinger Bandwidth strategy uses the Bollinger bandwidth indicator to measure the difference in percentage between the upper and lower bands of the traditional Bollinger Band® indicator. Where w can be any formula returning a numeric value. Where x is the period which must be an integer. Where d is the distance between the centerline and the Bollinger Bands in multiples of the standard deviation. Where z is the offset. An offset of 1 would be for one bar ago. Where t is the average type. Leave blank for simple, set to X for Bollinger BandWidth is an indicator derived from Bollinger Bands. In 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). BandWidth measures the percentage difference between the upper band and the lower band. An indicator formula for a Bollinger Bands %B with a Period of 50 set to 2.00 Std Dev using an Average Type of Simple can be written as follows for the current bar. (C0 - AVGC50.0) / 2 / 2 / STDDEV50.0 + .5. But we can leave off the offset parameters since these parameters would just be zero for the current bar. (C - AVGC50) / 2 / 2 / STDDEV50 + .5

For example the upper band formula would be MOV20+(2*20Standard Deviation of Close). 3 The third line is the lower Bollinger Band. To calculate the lower Bollinger Band you calculate the Moving Average of the Close and subtract Standard Deviations from it. For example the lower band formula would be MOV20-(2*20Standard Deviation of Close). Where w can be any formula returning a numeric value.. Where x is the period which must be an integer.. Where d is the distance between the centerline and the Bollinger Bands in multiples of the standard deviation.. Where z is the offset. An offset of 1 would be for one bar ago.

Bollinger Band Width Indicator. Bollinger's Bandwith Indicator is used to warn of changes in volatility. As we know from using Bollinger Bands, a squeeze where the bands converge into a narrow neck often precedes a rapid rise in volatility.

The idea, using daily charts, is that when the indicator reaches its lowest level in 6 months, you can expect the volatility to increase. Bollinger Bands can also help predict trend reversals. Bollinger Bands will appear as three lines on a chart. The middle line is the instrument's moving average, while the upper and lower lines are based on the standard deviation of the price movements. Popular trading strategies include identifying double bottoms, reversals and squeeze patterns. See full list on theancientbabylonians.com For example the upper band formula would be MOV20+(2*20Standard Deviation of Close). 3 The third line is the lower Bollinger Band.
