Venues disagree about what a funding rate is. Binance publishes an 8-hour rate on a fixed schedule. Hyperliquid accrues hourly. Native Robinhood Chain perps mark continuously. Before anything can be differenced, all three are normalised to the same 8-hour basis.
ΔFR = FR_robinhood − ( FR_binance + FR_hyperliquid ) / 2cashflow = size × ΔFR × Δt / 28800| Venue | Endpoint | Native interval | Normalisation |
