Net APR subtracts entry and exit fees, both legs' bid/ask spread and estimated slippage from the gross funding spread. The 7-day average is historical gross funding for the same pair: a current rate close to it suggests the spread has persisted, one far above it is usually a spike that will decay.

Trading the Extended / MEXC spread

The trade is one position split across two venues: long the exchange paying the more negative funding, short the one paying the more positive, in the same size. Direction risk is largely offset, and the position earns the funding difference each interval. What limits it is not the headline APR but the smaller leg's liquidity, the fees on both sides, and how long the spread survives — funding decays and flips, often within hours. Per-market detail, including a backtest, is on each market's funding page; the full calculation is in the methodology.
