According to your example, since it is an export order for six months, it means that you will get US dollars in the future. Since the contract has been signed, the income in dollars is certain. At this time, if the dollar depreciates, it will lose money. So, your risk lies in the depreciation of the dollar. Therefore, when signing a forward trade contract, short the US dollar exchange rate futures in the futures market. If the dollar really depreciates, although your spot sales income is a loss, your dollar foreign exchange futures are profitable, so the profit and loss are flat, which is hedging.

There are three points to note. First of all, your future must be consistent with your cash flow. In other words, if you earn US dollars in one lump sum after six months, you should short the US dollar foreign exchange futures delivered after six months. If you get dollars by the month, you can make futures by the month.

Second, the number of futures contracts you make must be equal to the number of dollars you get from spot sales, so that you can achieve complete offset.

Third, we should pay attention to the changes in the foundation. The so-called basis is the difference between the exchange rate of the US dollar in the spot money market and the exchange rate of the US dollar in the futures market. During the six months when you are doing futures, the exchange rate change of the US dollar in the spot market may be different from that of futures, resulting in the change of basis. If the basis changes, even if you achieve the first and second points, you can't completely offset the profit and loss, so you should adjust the number of futures contracts you hold according to the change of basis during the hedging period. If the spot changes more than futures, the number of futures contracts will increase, and vice versa.

Hope to adopt ~ thank you.
