My trade analytics suggest, "Your average holding time on indices is XX days. It's usually cheaper to hold futures contracts after 3-6 days." Apparently, it the funding is cheaper in Futures Contracts but will take some time to offset the large spread in its case compared to Cash Indices' low spread. My question is: What would be the funding rate if I enter a Futures Contract? When a Futures Contract reaches the maturity date, what happens? If I wish to continue to hold that Futures Contract, does it automatically roll over to the next Future Contract, or do we have to enter into a new Contract to continue to hold that Futures Contract?
