Oct 18, 2020 · Bollinger Bands are used as a technical analysis indicator. They are formed by using a 20-day moving average as a centerline and then tracing two bands, each one standard deviation wide, on either side of the moving average. By watching the share price's interaction with these bands, technical Bollinger Bands is one of the popular technical analysis tools, where three different lines are drawn, with one below and one above the security price line. Its specific period moving average is denoted as midline to form an 'envelope'. These lines show a band or a volatility range in which a particular security price is moving up or down. Bollinger Bands reflect direction with the 20-period SMA and volatility with the upper/lower bands. As such, they can be used to determine if prices are relatively high or low. According to Bollinger, the bands should contain 88-89% of price action, which makes a move outside the bands significant. 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 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. Bollinger Bands can be used in most time frames, from very short-term periods, to hourly, daily, weekly or monthly. Bollinger Bands answer a question: Are prices high or low on a relative basis? By definition price is high at the upper band and price is low at the lower band. That bit of information is incredibly valuable.
