If the subscription is successful before 15: 00 on that day, it shall be calculated according to the net value of that day. However, the net value of the fund will not be calculated until the evening. I didn't know when I bought it. You can only estimate the rise or fall based on the stock market.
If you want to know your net worth at the time of purchase, it may be enough to check the purchase date corresponding to the net worth table in two days.
