How about the unit price of soybean, corn, etc? Decide in the future? How much is it per ton? How much should I at least buy?
When the varieties in futures are listed, they shall be priced within the scope permitted by the state according to the actual price. After listing, the price changes all the time, but the strength of buyers and sellers rises and falls according to the transaction. The futures price is 1 ton, but when trading, soybeans and corn are sold in batches, and the minimum purchase price is 1 batch = 10/ton.
