How to trade basis
Basis > 0% + funding+
Perp more expensive than spot = longs overheated. Strategy: sell perp + buy spot (cash-and-carry). Wait for convergence to zero. Income = funding.
Basis < 0% + funding−
Perp cheaper than spot = shorts dominate. Strategy: buy perp (receive funding) or reverse carry. Usually short-term inefficiency.
Large basis ≠ go long
High basis doesn't mean "go long" — it means the market is already long-overheated. Correct reading: expect a correction or fade perp relative to spot.
