Total account income: the amount of money you earn, that is, the total market value-the cost of holding securities.
Balance: the remaining money except the securities you bought, that is, the total amount of funds in your account before you bought the securities, plus the cut-off cost of the securities you bought at that time. It can also be understood as the total assets of the account-the total value of the securities owned by the account.
Share: the number of securities you hold. For example, if you buy 100 shares of Vanke A, then the share of Vanke A is 100.
