Generally speaking, it's best for funds to be transferred out and redeemed before 15:00, because the fund valuation can be seen before 15:00, and it is generally recommended to transfer in before 15:00. You can consider whether to buy according to the fund valuation.
In addition, it is worth noting that the fund generally confirms its share at T+ 1 when buying and at T+ 1 when selling, so if you want to transfer in or out quickly, try to choose before Monday to Thursday 15:00.
