When you make a fixed investment, you will be asked to choose when to deduct the money automatically every month or week.

When making a fixed investment, if the fixed investment date is a non-trading day, the deduction will be postponed to the next trading day. However, you need to ensure that there is enough balance in the bank card associated with the day of deduction, so I suggest you check whether the balance of your bank card is sufficient the day before deduction. Generally speaking, if the deduction fails for three consecutive cycles, the plan will be automatically suspended.
