Bollinger Bands use the 20-period moving average line as the center “baseline.” The upper band is set two standard deviations above the baseline and the lower band two standard deviations below. One moving average is shifted upward, and the second moving average is shifted downward. Envelopes define the upper and lower boundaries of a security’s normal trading range.
