The Shanghai Futures Exchange quotes gold at RMB/g and silver at RMB/kg. Internationally, gold and silver are quoted in USD/oz. An ounce is equal to 365,438+0.65,438+0.035 grams, and the daily exchange rate of the US dollar against RMB is different. The People's Bank of China announces the exchange rate of US dollar against RMB every day, so the daily quotation of domestic gold and silver futures is converted according to the exchange rate of that day. Because the trading time of gold and silver futures is limited, there are only four hours of trading time during the day, while gold and silver are traded continuously around the world for 24 hours, so many markets are missed, and overnight orders often have the risk of opening higher and leaving lower. There is really no fluctuation in the four-hour trading session. Of course, if you are doing a long-term trend, there is another advantage that the handling fee is relatively cheap and there is no charge for staying overnight.
