Looking at Wikipedia's the pricing of futures, I wonder if entering into a futures contract requires one to pay premium just as entering into an option contract? In other words, is the premium of a futures contract always zero?
Is futures price similar to exercise price of an option, or to premium of an option?
Is pricing futures in Wikipedia's the pricing of futures to determine the premium for entering the futures contract, or the price at which to buy or sell the underlying assets at the future maturity time?
Thanks and regards!
