The first explanation: because of your reasons, you can't continue to invest in a certain fund, so as long as you submit to stop or cancel the investment, the fund company will immediately stop your deduction next month and beyond. But your fund share is still displayed in your fund account. If you want to sell the fund, you have to redeem it with the fund.
The second explanation: if you want to buy again after 5 years of fixed investment, you only need to go through your previous purchase procedures again, no problem. Fund companies welcome your attention!
