STH Realized Price.
155-day volume-weighted average price. The cost basis of the asset's most recent buyers.Price is more than 20% above the cost basis of trailing buyers. Late-cycle behavior — those who bought in the last 155 days are sitting on outsized gains and historically begin distribution from this band.
Price has fallen below the 155-day VWAP. Most recent buyers are in loss. Historically these zones precede the strongest forward returns — the market is shaking out weak hands while patient capital accumulates.
On Bitcoin this metric averages the cost basis of UTXOs aged under 155 days. The 155-day threshold separates short-term holders (reactive) from long-term holders (high conviction). Crosses of the line tend to mark regime shifts.
Without per-wallet cost-basis data, we approximate it with a 155-day volume-weighted average price: STHRP = Σ(price × volume) ÷ Σ(volume). Days with heavier volume weight the average more, which matches the spirit of the original.
The streak counter shows how long the current regime has lasted. Long streaks above STHRP often align with mid-to-late bull runs. Long streaks below align with major capitulation zones — historically the best accumulation windows.
Premium reads as price ÷ STHRP − 1. Sustained positive premium means a hot market; sustained negative premium means distress. Mean reversion back to the line is the dominant pattern over multi-month horizons.
