- Higher Band: This line sits a sure variety of commonplace deviations (normally two) above the center band.
- Decrease Band: This line sits the identical variety of commonplace deviations under the center band.
The usual deviation is a statistical measure of volatility. By utilizing commonplace deviations, the Bollinger Bands® adapt to the worth motion of the safety being analyzed. In essence, the broader the bands, the upper the volatility, and the tighter the bands, the decrease the volatility.

Center Band (MB): MB = SMA (Worth, n)
Higher Band (UB): UB = MB + (Ok x Commonplace Deviation (n))
Decrease Band (LB): LB = MB – (Ok x Commonplace Deviation (n))
The place:
- n = Variety of intervals used for the SMA (usually 20 days)
- Ok = Variety of commonplace deviations (usually 2)
