Options are divided into call options and put options. Call option is a kind of legal contract, which gives the option holder the right to buy a certain number of assets or futures contracts at a specific price at a specific time or at any time before. Put option gives the holder the right to sell a certain number of assets or futures contracts at a specific price at a specific time or at any time before that. The holder of the option has the rights stipulated in the option, which he can exercise or give up, while the seller of the option has only the rights.

Futures refers to commodity futures, and futures refers to stock index futures. There is no capital threshold for commodity futures, and the stock index futures account needs 500,000 yuan.
