Fund net position cost = (subscription amount/confirmed net value-subscription fee)/confirmed share. Unit cost is the average cost of holding funds at present. For example, if you buy a fund in batches for many times, the unit cost reflects the total average cost of the fund.

Dilution cost = total confirmation of purchase or transfer-total confirmation of sale or transfer-total confirmation of cash dividend-total confirmation of forced redemption. In addition to monetary open-end funds, general funds are based on the net difference at the time of redemption or the difference at the time of trading to judge the income.
