Customer margin refers to the funds deposited by the customers of securities institutions to ensure the full delivery of securities, all the proceeds from selling securities (excluding brokerage commission and other legal expenses), dividends from holding securities, cash dividends, bond interest, interest from the above funds and other funds recognized by China Securities Regulatory Commission.

Securities company customer margin can be used for stock trading. Because stock trading must first have funds to buy, so funds are also called trading margin.
