No, the weekend is not trading time. Funds bought at the weekend will be traded next Monday. According to the net value at the close of next Monday, the share will be confirmed next Tuesday. Therefore, buying a fund on weekends is the same as buying a fund on Monday. It is better to buy a fund if it falls. When it falls, the cost for investors to buy is lower, and the lower the cost, the less risk investors bear.

Investors can decide whether to buy the fund a few minutes before the close. Before the close, they can know the rise and fall of the fund by looking at the net worth estimate. They can buy when the fund goes down, but they don't buy when the fund goes up.
