When purchasing a fund on T+ 1 day, the fund company generally confirms that the share will arrive at the account at 5 pm on T+ 1 day (QDII funds need 2 trading days). Tips: T Day refers to the trading day, which is bounded by the closing time of the stock market 15. The purchase before 15 is counted as the transaction of the day, and the purchase after 15 is counted as the application of the next trading day.
