EndpointCross-venue funding spread per coin: the venue with the highest and the lowest annualised funding (current rates or predicted next rates), the spread per year and per day and the smaller open interest of the two legs. A difference between published rates, not an executable return (fees, price moves, funding times). Licence review: a spread involving Binance / Bybit is listed only when at least 3 venues quote the coin and both ends are exchanges whose rates are withheld (a published rate at one end plus the spread would give the other exchange’s rate); such legs keep their venue, their own fundingApr and openInterestUsd are null (meta.restricted).
