Yes, non-trading hours can be terminated. Take Alipay as an example. The termination process is as follows: open Alipay APP-click on wealth management-click on fund-click on holding fund-my fixed investment-select fund-click on management-terminate.

After the fund's fixed investment is terminated, the fund will not continue to make fixed investment, and the fixed investment plan will be cancelled, so investors cannot recover. If it is necessary to continue to make a fixed investment, then investors can only re-formulate the fixed investment plan.
