Futures contract refers to the standardized contract formulated by the futures exchange, which stipulates that a certain number of subject matter will be delivered at a specific time and place in the future. Some American futures contracts, such as soybeans and copper, will have an impact on domestic futures prices. Domestic investors can refer to the external market. Large producers and traders can also hedge spot trading losses according to the external market.
You can't do foreign sales at home, but you can only do it abroad, such as Hong Kong and the United States.
