The normative definition of fixed-term investment is a fund investment mode in which an investor applies through a designated fund sales organization, agrees in advance on the deduction date, deduction amount, deduction method and the name of the invested fund, and the sales organization automatically completes the deduction and subscription in the bank account designated by the investor on the agreed deduction date.

Investors spend their investment amount in a fixed time interval. If the investor cannot continue to invest as agreed, the bank or fund company will not ask the investor for compensation or continue to invest. Some banks stipulate that the fixed-term quota agreement will be automatically cancelled if the investment fails for three consecutive periods. Some banks will implement the agreement as long as you have money in your account, and will not implement it if you have no money. There is no deadline. Some banks can apply at any time and cancel at any time.
