Customizing Bollinger Band Outer-Band Smoothing

Summary

This indicator description presents a variation on Bollinger Bands that lets traders smooth the upper and lower outer bands independently. The upper-band smoothing period can therefore be adjusted without changing the lower band’s setting, and vice versa. The described method retains the original Bollinger Band calculation, applying an additional moving-average period to an outer band. A separate additive setting determines whether the smoothing period is added to the base Bollinger Band period or treated as an independent period. This offers control over the bands’ responsiveness while leaving the middle-line period as a separate reference when additive smoothing is disabled. The document gives no formula details beyond this description, parameter guidance, trading rules, or performance evidence. Smoothing changes indicator behavior, but the text does not establish whether it improves signals or results.

Key ideas

• The indicator allows separate smoothing settings for the upper and lower Bollinger Bands.
• Outer-band smoothing adds a moving-average period to the standard band calculation.
• An additive option combines the smoothing period with the base band period.
• The description provides no trading rules or evidence of improved performance.
