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.
Coverage note: dYdX and Lighter share 13 markets, 2 of them with real depth — below the 10 markets / 5 liquid this page treats as full coverage, so this is a thin sample rather than a picture of the pair.
