Moreover, there are many kinds of discounts, and there are two commonly used ones: spot discount and grade discount.

For example, if the price of 1 1 month futures is lower than the spot price in the current market, it is spot premium, and the higher part is also called spot premium.

At the time of delivery, if the delivery level of the goods is higher than the delivery level required by the exchange, there will be a delivery level premium (the buyer has to pay this part); If it is below the requirements but acceptable, the opposite is true.
