Fixed investment is to deduct money after the fund is sold. Selling funds only sells the fund shares currently held. Fixed fund investment will continue. It is a buying fund with a fixed time limit set in advance. As long as there is money in the account, the system will automatically deduct money to buy the fund.

If investors don't want to make a fixed investment, they just need to terminate the fixed investment in my fixed investment, and they need to operate after the fixed investment deduction date 15.
