Your subscription price is the net value of the day announced later today, because the fund implements the principle of "unknown price pricing", that is, you don't know the specific price when you subscribe, and the same is true for redemption.
In addition, I would like to suggest that, in my opinion, you can trade between 2: 30 and 3: 00 pm according to the current valuation of some fund portals to reduce the blindness of trading.
