Fund position cost = {(net fund subscription value * fund share)-handling fee}/fund share. The cost of holding positions does not need to be calculated manually by the investor, but will be directly displayed in the investor's account.

Generally, when the net value of the fund is higher than the cost price of the position, the investor is profitable. If the net value of the fund is lower than the cost price of the position, the investor is losing money. The net value of the fund is determined by the investment target. Investment targets rise, funds rise, investors gain, and investment targets fall, resulting in investors' losses.
