What it measures
For every UTXO spent in the trailing 24 hours, the ratio of spent price to created price, averaged across the window.
Network-level signals derived from the live UTXO set: valuation, holder distribution, profit-taking behaviour.
How it is computed
SOPR = mean(spent_price_usd / created_price_usd) across all UTXOs spent in the last 24h with both prices populated. Computed daily from the spent_utxos archive written transactionally by utxo-tip-follower for each new block.
Available windows: snapshot. Default: snapshot.
How to read it
SOPR > 1 means spent coins were realising profit on aggregate; SOPR < 1 means losses. Sustained moves through 1.0 with the 7-day average flipping sign mark behavioural regime shifts — bull-market support tests vs bear capitulation events.
