Bollinger Bands® identify asset prices that have deviated from the mean. In range-bound markets, mean reversion strategies can work well, as prices travel between the two bands like a bouncing ball. However, Bollinger Bands® don't always give accurate buy and sell signals.
Another indicator used with Bollinger Bands is %b, which plots the stock's closing price as a percentage of the upper and lower bands. The upper band is identified as 1.0, the middle band 0.5 and the lower band zero. Thus, %b shows how close the stock's current price is to the bands.
