Counts reflect successful reads for this page. Storage errors can reduce the counts, including to zero.
Original collection began July 16, 2026, at 11:09:08.181 UTC, according to persisted version 1 metadata. Version 2 began September 12, 2026, at 08:52:28.326 UTC. Version 3 starts with the first sweep after the September 23, 2026, release. Version 3 reads the funding interval of each market from the venue feed. Version 4 starts with the first sweep after the September 25, 2026, release. Version 4 makes each predicted row point at the next settlement after the observation time. The charts and the default API series join version 2, version 3, and version 4 at the first sweep of each version. The hourly rates are the same quantity in all three versions for BTC and ETH. On version 2 Aster and Crypto.com rows, the raw rate and raw interval are empty. The methodology page gives the reason.
Latest available BTC sweep: 2026-10-24 19:37:28.294Z. Latest available ETH sweep: 2026-10-24 19:37:28.294Z. Sweep timestamps identify collection runs. A requested period can contain missing observations.
- BTC current-rate aggregates, version 4 only and ETH current-rate aggregates, version 4 only.
- Binance BTC current-rate CSV, including raw rate and interval.
- BTC realized settlements and ETH realized settlements, with venue coverage.
- Earlier BTC funding aggregates, version 3, version 2, and version 1.
Current-rate downloads report observation count, latest time, and coverage ratio for the returned window. Realized records come from venue settlement-history windows and can predate PerpFinder's collection. Their settlement date records a venue event; it does not establish when PerpFinder observed that event.
Funding history by venue
Each venue page shows the stored BTC and ETH funding by UTC day, with a CSV download. Venues with a collected settlement feed show settled rates. The other venues show 15-minute current-rate readings.
Basis vs index, per venue
Basis vs index · BTC
UTC daily median-4.72 bpsBinance mark price against its own index price, in basis points. Positive means the perp traded above the index that day. Window starts 2026-09-25 · sweeps stored since 2026-07-16 · established series.
Median of 2,861 stored sweeps over the 30 days shown. 24 of 27 covered venues publish a mark price but no index price, so their basis is not computable and is left out — never shown as zero.

Basis is the mark-price gap against the same row's index price, expressed in basis points. One basis point equals 0.01%. Each daily point is the median of available samples for that venue. Missing daily samples leave a line break. These price-basis charts read stored rows across funding versions; the displayed maturity label describes the current funding version.
How this series is built
The collection target is one BTC and one ETH sweep every 15 minutes. Funding-rate charts and cumulative-payment charts are not displayed on this page. The API downloads contain the funding observations; the charts contain price basis. There is no synthetic backfill of missing funding sweeps. The methodology defines intervals, timestamps, and source limits.
