Connection and difference: Futures is a standardized forward contract traded on the exchange. Due to the handling fee charged to the exchange, its default risk is lower than that of forward contracts, and the transaction cost is higher.

Option trading is the right to return under certain conditions within a certain period of time, and it is a derivative tool based on the underlying assets. Theoretically, there are stock options, real options and futures options. But without option futures, futures cannot use options as the underlying assets.
