One of the functions of futures is to find the price. Theoretically, the spot price is the same after the contract expires. But not all goods can apply this theory. There are many factors that affect the price trend. Speculative varieties such as silver do not necessarily have much linkage with the spot, but should pay more attention to the trend of silver in the outer disk.

Specifically, the spot delivery corresponding to futures contracts requires varieties and quality. For example, just listed peanuts, the benchmark delivery areas are Henan, Shandong and Hebei. Then the futures price should be compared with the spot prices in Henan, Shandong and Hebei. If compared with other non-benchmark delivery areas, the price is naturally much worse.
