When selling soybean call options, if the soybean price rises at the expiration date and the counterparty demands to exercise, it is necessary to sell soybeans at the agreed exchange rate (the buyer of the call option buys soybeans).

Customers who hold long positions in soybean futures can use the futures long positions for delivery if the options need to be exercised when they expire, and the difference between the futures purchase price and the delivery execution price forms a fixed profit and loss. If the option does not need to be delivered, the customer gets the option fee income.
