The opening period of the fund is generally not more than 6 months. The timing and duration of opening positions are determined by the fund manager, who will adjust positions and exchange shares in real time according to market conditions. If the fund is in a weak market, the fund manager may not need to complete all positions.

In fund trading, investors can choose funds that have been in business for a long time or managed by star fund managers, and the fund income has a great relationship with the investment level of fund managers.
