After ETF is raised, it is necessary to open a position, during which there may be profit or loss. There must be a share conversion date after opening the position, and the conversion ratio has the formula: (X/Y)/(I/ 1000).

X is the net value of the converted fund, Y is the fund share before conversion, and I is the underlying index, so that after conversion, this part of the fund's profit and loss during the opening period can be weighted and averaged to the existing index. Then multiply this ratio by the fund share before conversion to calculate the total share after conversion. Divide the converted total share by the converted net value of each fund to get the converted net value of each fund.
