Excuse me, do you want to ask "What does the overall difference between futures and current prices mean"? The meaning of this term is as follows:

The overall spread between futures and futures refers to the difference between spot price and futures price. The basis can be used to guide futures trading, hedging and futures trading.

When the basis difference is small, it means that the futures and spot prices are close. If you are worried that the spot price will fall, you can hedge the risk of falling prices by selling futures in the futures market; when the basis difference is large, it means that the futures price will be lower. is less than the spot price, at this time it is more cost-effective to purchase through the futures market than purchasing the spot directly through the spot market.
