If you buy a fund at the counter before 3 pm, you can confirm the fund you bought on the next working day (except Saturday and Sunday), and you can see your share after confirmation.
If you bought the fund at the counter after 3 pm, it is equivalent to your application for the next working day. You need to wait T+2 working days (excluding the same weekend) to confirm that you see your share.
Your share = confirmed amount/net fund value
Confirmed amount = subscription amount-subscription fee
Subscription fee = subscription amount * subscription rate
In the future, your income is the share you hold * the net value of the day.
