Funding rates are public perpetual-market data. This site re-pulls these public endpoints every 15 minutes:
fapi.binance.com/fapi/v1/fundingRateapi/v5/public/funding-rate-history“30d annualized” = average rate of the last 30 days of settlement records × settlements per year (computed from each exchange's actual settlement interval). All data is public and free.
The methodology follows a full research pipeline over Binance BTCUSDT perpetuals, 2021-09 → 2026-08 (5,458 funding records): yearly distribution, negative-rate share (14.7%), longest negative streak (6 days), monthly timing backtests, leverage sensitivity (1x/2x/3x × borrow cost), and multi-coin dynamic switching backtests (no look-ahead, full trade costs). Result: +7.4%/yr at 1x unlevered; up to +16% at 3x with low-cost borrowing; monthly peaks reached +37% annualized (2024-03).
