The purpose of forward is basically based on physical transactions, and it is only to buy or sell in advance and not to hedge futures.

For a typical example, please refer to LME exchange, which is a typical forward contract exchange.

CBOT is a futures exchange.

LME contracts are forward contracts with rolling delivery.

For example, you/kloc-0 bought 25 tons of CU 1 lot on October 6th, and the delivery date is February 6th after March. If you sell your position on 10/8, you will sell your position. The premium for these two days will be deducted from your profit and loss.
