This moving average indicator is a bull market support band. It's significance comes from the previous bull runs where the price was bouncing off or riding from a distance the support band until the end of the market cycle. For example, during the 2017 bull run, Bitcoin had several 30-40% corrections to the support band.

Very simple and effective S/R band. Created bycombining the weekly 21EMA and weekly 20SMA, it provides strong support/resistance depending on market direction, and works as a basing area for retraces during parabolic (and normal) bull markets.
