Advantages: 1, 24-hour trading, opening on Monday morning and closing on Saturday morning, and can be bought and sold at any time. 2. Margin trading has its own leverage, with sufficient profit margin and no price limit. 3. The mainstream trading varieties are gold, crude oil, copper, Hang Seng Index, S&P and seven foreign exchange currency pairs. There are very few trading varieties without the trouble of stock selection. 4. Take profit and stop loss can be set, and less stop loss can make more profits. The disadvantages are also obvious, because the leverage effect of foreign exchange magnifies both income and risk, which requires investors to have a higher risk awareness. In addition, there is no unified market for foreign exchange in China like stock futures, so it will take some time to find a reliable platform if it is to be done for a long time.
