Futures and spot are completely different. Spot is actually a tradable commodity. Futures are mainly not commodities, but standardized tradable contracts with some bulk products such as cotton, soybeans and oil and financial assets such as stocks and bonds as the targets. Therefore, the subject matter can be commodities (such as gold, crude oil and agricultural products) or financial instruments.

Call option, also called call option, call option, call option, call option, call option, call option or "knock-in", means that the option buyer has the right to buy a certain amount of the subject matter at the strike price within the validity period of the option contract. A call option is a contract that gives the contract holder (that is, the buyer) the right to buy a specific number of specific trading objects from the opponent at an agreed price.

Put option is also called put option, seller option, put option, put option or elimination option. Put option means that the buyer of the option has the right to sell a certain number of the subject matter at the execution price within the validity period of the option contract, but does not undertake the obligation of selling.
