Because it is the most difficult thing to exchange foreign futures at home and abroad, even if the registered address of the head office is in Hong Kong, it is not easy to exchange foreign exchange flexibly in real time. In fact, for convenience, many exchange rates are exchanged at one time at a certain node, and then the exchange rate rises or falls in time. Because the exchange rate has been centralized, it can only be calculated according to the centralized exchange rate, but even so, the fixed exchange rate will change, because once the exchange rate is used up, it can only be calculated according to this exchange rate. But because the profit is calculated in real time in the market, the net profit of the order is calculated according to the actual exchange rate.

If foreign countries, such as Hong Kong, have a good index cycle, is the exchange rate of US gold and US crude oil futures calculated according to the actual exchange rate? If the exchange rate in Hong Kong is relatively open, for example, HSBC and major banks in Hong Kong open accounts for the Hang Seng Index, because Hong Kong banks have the function of real-time exchange of foreign exchange, deposits and withdrawals are calculated according to the real-time exchange rate, but domestic and foreign futures companies can only carry out exchange business in the form of intermediaries, and cannot do real-time exchange.
