Bull Market Support Band
Price relative to the Bull Market Support Band — the higher of the 20-week SMA and 21-week EMA — a widely watched trend floor.
At $76,620, BTC trades 0.97× its Bull Market Support Band ($78,961, the higher of the 20-week SMA and 21-week EMA). Prices holding above the band have historically marked bull phases and below it bear phases; this describes position, not direction.

Off daily close through 2026-05-24 (btc-history.json). Price lags ~30d; live tail is a Phase 2 stitch.
How it's computed
The band is the greater of the 20-week (140-day) simple moving average and the 21-week (147-day) exponential moving average. Divide the daily close by that band level. Holding above the band has historically marked bull phases and below it bear phases; this describes position, not direction. Computed off the daily close through the latest available row in btc-history.json (a price-only community feed that trails the live market by roughly 30 days); the tail therefore lags today by about a month.
