Take Beijing as an example, each phone lines costs 3000 Yuan to install. The monthly fee is 600 Yuan. Thus a brokerage office with 100 lines has to pay 300,000 Yuan installation fee plus 720,000 Yuan per year. Trading via Dial-Up Connection With a computer and a modem, investors can dial into their brokerage office and trade stocks online. But since each caller still occupies a line, the limitation on the number of phone lines is still a problem.
Internet requires that the security exchange system be connected to the Internet.
Investors can trade online through a web browser. No phone line is required on the brokerage office. This method allows investors to trade any time and from anywhere. Investors can stay online all day long without worrying about being disconnected. Although Brokerage office can be protected by firewall, the security of individual investors can not be guaranteed.
