Bollinger Bands is an important technical indicator used in chart analysis. A technical indicator that draws bands based on standard deviations above and below a moving average. When using 2-sigma (2 standard deviation) bands, assuming a normal distribution, statistically about 95% of prices are expected to stay within the bands. While prices moving outside may suggest a potential reversal, in strong trends prices can continue to ride along the band in a phenomenon known as a "Bollinger Band walk," so caution is needed.
