At ten o'clock in the morning, I bought the "Interest A" fund with donghai securities's software. Why does it always show declared but not closed? What happened?
You bought an open-end fund. If so, buying during trading hours means that you have declared that there is no deal. General securities companies will report your data after the close of the day, and make a deal on the second trading day, which is the price of your first trading day (open-end funds only have one price every day). The same is true of sales.
