1. Overseas futures refer to futures transactions where the exchange is located outside Chinese mainland. Products in exchanges in the United States, Britain and other countries are usually traded futures contracts. 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.
2. Maintenance margin refers to the funds needed to maintain a position. Generally, it is about 75% of the opening margin. Take Meijing Copper as an example. If you buy a second-hand opening margin, the margin amount is 9450 USD, and the maintenance margin is 9450X75%=7087 USD. When the loss of the position is less than $7,087, you will be informed of the additional margin (the obligation of the futures company is actually to close the position). When the position is less than half of the maintenance margin, that is, 7087x50% = $3,543 (the loss has been 62.5%, and the open position has been consumed by $5,906.25), the futures company will forcibly close the position. If you operate heavily, such as holding 90% positions, when losses occur, you will constantly withdraw funds from unused funds, and your available funds are very small, so you will often be out before reaching 75% of the maintenance margin line. However, this kind of explosion is different from the explosion with negative losses. Because of the heavy warehouse operation, the customer's account funds are still huge after the explosion, and the loss is actually very small, so the heavy warehouse operation is not terrible.
3. Futures companies that set up branches in China and Hongkong can act as agents for futures account, and domestic investors can handle it directly through the domestic sales offices of these companies. However, because the foreign futures settlement currency is US dollars, investors need to go to the bank to convert RMB into US dollars before they can deposit. The free exchange limit is 50,000 US dollars, which is about 300,000 RMB. Deposits are made through account remittance provided by futures companies, and there is still no bank-securities transfer business.
