About funding rate
Perpetual futures have no expiry, so funding is the mechanism that keeps them tethered to spot: when the perp trades above spot the rate goes positive and longs pay shorts, and when it trades below the flow reverses. A rate of 0.01% every eight hours sounds negligible and annualises to around 11%, which is a substantial drag on a position held for months — or a substantial yield if you are on the receiving side. This converts a per-interval rate into what it actually costs over the period you intend to hold.
