This is the home of the Bitcoin ETF flow tape: completed-session totals, constituent products and rolling windows. The 29-page reference included these fields; the current validated daily dataset does not yet contain a comparable flow series.

What a flow table must say
Each line needs the product identifier, completed trading session, reporting currency, source and revision state. A market holiday is not automatically a zero-flow session. A missing product cannot quietly be excluded from a supposedly complete total.
Rolling seven- or thirty-day figures must say whether they use calendar days or trading sessions, and whether they sum net creations/redemptions, cash estimates or another measure.

Why holdings do not answer it
IBIT publishes product and holdings information with field-specific dates and valuation notes. Our accepted daily balance is useful context, but a change in the dollar value of holdings can reflect a price move. Even coin-count changes require the fund’s accounting context before being called investor cash flows.
