Why use it. Compare the change in current spendable value over a stated daily span. How to read it. Positive means more spendable value at the ending snapshot; negative means less. This is a difference of stocks, not gross transaction volume or a sum of daily stock levels. It needs 31 daily points, including both endpoints. Missing endpoints leave a gap; partial/final labels apply and an unchanged stock gives zero.
Calculation. Use local canonical unspent value after the highest block height assigned to each UTC day. Compute change(a,30), the current BTC stock minus its value 30 daily observations earlier, with 40-digit Decimal arithmetic. Genesis, provably unspendable outputs and BIP30 overwrite losses are excluded; changes reflect issuance, spending/creation balance and those exclusions. Proved empty days carry the accepted stock snapshot. No price or entity classification is used.
