The so-called trading day is the day when you apply. The working days of fund companies and exchanges are synchronized. Closed from Saturday to July, 9: 30am-3: 00pm on Saturday working day 1-5. Because online direct selling is a 7*24-hour all-weather transaction, the concept of "trading day", that is, "T", has come into being. Normal trading day, before 3 o'clock, the next day after 3 o'clock. From 3: 00 p.m. on Friday to 3: 00 p.m. on Monday, a trading day is counted as one week 1.
