The difference between options and futures-the connection between futures and options-is that they are traded in organized places-futures exchanges or options exchanges. Standardized management of exchanges. On-site transactions adopt standardized contract methods. The exchange uniformly formulates its trading quantity, minimum price change, price limit, trading unit, contract month and other standards. There is a unified clearing institution in liquidation, which plays a guarantee role in liquidation. All four people have influence. The difference between options and futures: the carrier of different standardized futures contracts is the underlying assets, and the only variable is that the price carrier of futures contracts is futures contracts, that is, the price (execution price) of futures contracts is certain. The only variable is the rights and obligations of the buyer and seller of royalties. Both parties have corresponding rights and obligations, and are obliged to perform liquidation or delivery at maturity. Most transactions are made by the seller's application for delivery. The buyer of the option has the right to decide whether to exercise or give up the right, and the seller only has the obligation to perform as required. The performance bond stipulates that both parties should pay the deposit, the option seller pays it and the buyer only pays the premium. The risk-return structure of both parties is symmetrical and asymmetrical.
