Formula

perpFundingAprPct = fundingRate * (24 / intervalHours) * 365 * 100

expectedFundingToExpiryPct = perpFundingAprPct * daysToExpiry / 365

carryEdgePct = expectedFundingToExpiryPct - datedBasisPct

netCarryEdgePct = sign(carryEdgePct) * max(0, abs(carryEdgePct) - roundTripFeePct) — the carry edge net of the averaged per-venue round-trip taker fee (roundTripFeePct), keeping the edge's sign and floored at 0. carryEdgePct itself stays gross.
