Financial futures is a kind of futures trading. Futures trading refers to the trading of standardized futures contracts in a centralized trading market by open bidding. Futures contract is the object or subject matter of futures trading, which is uniformly formulated by the futures exchange and stipulates a standardized contract to deliver a certain quantity and quality of goods at a specific time and place.
