Funding rate arbitrage basics: delta-neutral income across exchanges
Long where funding is cheaper, short where it is richer — up to three settlements a day, without betting on direction.
Perpetual futures pay or receive a funding rate every eight hours on most venues. Rates diverge because leverage demand differs by exchange and by coin.
A classic funding arb is long the low-rate venue and short the high-rate venue in equal notional size. Spot price moves cancel out; the edge is the funding differential after fees.
Arbitrex surfaces live funding spreads next to futures and spot-futures routes so you can compare strategies on the same screen before opening a trigger.
