Over the last 30 days, holding long MEXC / short Aster would have produced 4.6% APR — versus the 5.7% the live spread implies right now (equity $10,000 → $10,038). This is a backtest on historical funding, not a live result: funding drifts and decays, so backtested results rarely match the current headline rate — which is why size and holding window matter more than the top-line number.

Funding arbitrage combines opposing positions on two venues — long the one paying the most negative funding, short the one paying the most positive — to reduce directional exposure and capture the difference between their funding payments. Fees, slippage, basis divergence and liquidation risk can reduce the result. See the methodology for how it is measured and the guide for the full walkthrough.
