The last trading day on Monday is Friday, and you can see the fund's income on Friday and Saturday. If you don't trade the fund on weekends, you won't generate income, so there is no fund income on Monday.
The trading hours of funds are the same as those of stocks. Monday to Friday are 9: 30 am-11:30, and afternoon 1:00-3:00. Do not trade on weekends and legal holidays, and do not trade without generating income.
