Apply for the fund before T day 15, and confirm the fund share on T+ 1 Sunday afternoon 17. Purchase the fund after 15, and confirm the fund share on 17 the next trading day (QDII funds need two trading days to confirm). To subscribe for a new fund, you need to wait until the fund is established to confirm the share, and you can pay attention to the fund announcement when it is established. Tips: T day refers to the trading day, which refers to the opening time of the stock market from Monday to Friday, and is bounded by the closing time of the stock market 15.
