How do you carry out basic trading transactions in the secondary market?
First, shareholders place orders with securities companies.
Next, the securities company that received the order places an order on the stock exchange, and the stock exchange buys and sells shares; once the transaction is completed, the results are reported to the securities company, and furthermore, the securities company reports the results to shareholders.
