Basis Trade vs Cross Margin

A market-neutral derivatives strategy that earns the funding rate premium by simultaneously holding a long spot position and an equivalent short perpetual futures position; the two legs offset each other to create a delta-neutral position that collects funding payments from the short leg.

A margin mode in which the entire account balance is available to prevent liquidation of any open position; useful for hedging strategies with offsetting positions, but risks total account loss if a large position moves severely against the entire book.
