The price in the futures market includes the transaction price of the day and then, which is almost the same as the market price of the actual commodity. The price of futures in other months, that is, forward price, is the expected price of a long-term trend of commodity prices in the futures market, which may change greatly and there is no lack of manipulation. Therefore, people who do futures generally don't care much about the transaction price of the current month or day, but are more interested in the long-term price trend, because futures earn the spread profit by price changes.

The transaction price of the actual commodity is the transaction price of the spot market, and no special attention will be paid to the forward price trend. However, the spot market is now more and more interested in the price of the futures market on trading days. Many commodities will be priced with the trading price on the first day of the futures market as a reference, and the purchase quantity, shipment quantity and inventory will be determined according to the forward price trend of the futures market.
