Bollinger Bands® are drawn in a fill style and appear with a colored background, which in many cases makes them more visible.

The indicator center line consists of a universal moving average with two types of smoothing, and each smoothing can be chosen from a dozen possible versions:

It should be noted that the Phase1 and Phase2 parameters have completely different meanings for different smoothing algorithms. For JMA, it is an external phase variable that varies from -100 to +100. For T3, it is the smoothed ratio multiplied by 100 for better visualization; for VIDYA, it is the CMO oscillation period; for AMA, it is the slow EMA period. In other algorithms, these parameters do not affect smoothing. For AMA the fast EMA period is a fixed value, equal to 2 by default. For AMA, the ratio of raised powers is also equal to 2.

The indicator uses the SmoothAlgorithms.mqh library class (must be copied to terminal_data_folder\MQL5\Include). The use of the class "Average price series for intermediate calculations without using additional buffers" is described in detail in the article.
