The total profit and loss in the stock account is the sum of the profit and loss of all stock operations of investors, including the profit and loss of positions and the profit and loss of clearance. When I first bought stocks, the total profit and loss was the same as that of the day, and then it began to change. In addition, if a stock is cleared, its profit and loss record will be subtracted from the position profit and loss, and will enter the clearance profit and loss. Therefore, if you want to inquire about the total profit and loss of investors since their investment, you can find the profit and loss in the following two ways: inquire about the transfer records of bank securities, subtract the total amount of transferred funds from the total amount of transferred funds, and then compare it with the current market value of securities accounts. Contact the brokerage firm, check the inflow and outflow of funds through the counter, and then compare it with the total assets of the account, and you can also calculate the profit and loss.

Therefore, when looking at the total profit and loss of the stock account, we must look at it as a whole, and at the same time we must analyze the profit and loss range of the stocks in the portfolio, instead of always selling profits and retaining losses. Otherwise, your stock account will always be full of loss-making stocks and unprofitable stocks. On the whole, the possibility of loss (probability) is greater than the possibility of profit, because it needs to increase more than the degree of decline when it falls.
