The premium or discount means the price difference. But Shanghai Copper has many forward contracts, although the premium generally refers to the premium for three-month copper. I don’t know which month the closing price of your futures contract is. There is also a premium in spot trading, which refers to the difference between the spot price at a specific location and the futures contract price of the same commodity that is about to be delivered at that time. Mainly to balance shipping loads and other costs. If the location is very close to the delivery location, the premium will be very low.
