You can take the initiative to apply to stop the fixed investment agreement, or you can stop saving money in the fund's fixed investment related account. If the fund company does not draw money for three consecutive months, it will automatically stop the fixed investment agreement of the fund.

In your case, there is no money in your card for one month, you just need to deposit enough money next month, and then the bank will deduct the money for two months (the last month)! It won't have any impact on your fund's fixed investment!
