I'm not sure about this foreign exchange. Why can't we trade on the exchange again? Here's the thing. The stock exchange has opened many seat numbers to securities companies. If you want to trade stocks, you must have an account, just as you need a bank account to save money in the bank. If you want to trade stocks, we can only open an account in a securities company. The stock exchange will not open accounts for individuals, otherwise all investors will go to Shanghai or Shenzhen, which is too inconvenient. The securities market can be divided into primary market and secondary market. The primary market is the distribution market. Because shareholders' funds are limited, we can't participate directly. Only the company's major shareholders can directly participate, and shareholders can only participate in the primary market by playing new shares. The secondary market is a circulation trading market, where investors trade. Apart from paying taxes, the rest is almost the income of securities companies.
