Live Bitcoin Bull Market Support Band — the zone between the 20-week simple moving average (SMA) and 21-week exponential moving average (EMA). Bitcoin is the asset the Bull Market Support Band is most associated with — the 20-week SMA / 21-week EMA band has historically acted as a key support zone during BTC bull markets and as resistance in bear phases.
When BTC trades above the Bull Market Support Band, the band tends to act as support; inside the band signals indecision near the longer-term trend; and a weekly close below the band is often read as a loss of bullish momentum. The band is a trend reference, not a guaranteed signal.
