No need. If you buy a fund on a trading day, you can buy and sell it on the third trading day and sell it at any time. There is no holding time for fund transactions. When investors buy closed-end funds, they need to hold them until maturity, and no transactions can be made during the closed-end period.

It should be noted that the long-term holding of funds is better, and historically, the probability of making money from long-term holding is higher, and the fund invests in a basket of stocks, and the stock market is short and bears are long, and the probability of earning income from long-term holding is relatively high.
