When buying a fund, if the bank card balance is insufficient, investors need to transfer the money to the debit card or deposit the cash in the debit card first, and the system will deduct the money before three o'clock. If the money has been saved and the system is not buckled, investors can buy it manually. If the investor has money in the bank card, but the balance is insufficient, it may be the reason for the second-class card. The second-class card only has a daily limit of 6,543,800 yuan, and it can't be used if it exceeds the limit. If the balance of the fund is insufficient when deducting from the fixed investment, the general system will continue to deduct in the later period and terminate the fixed investment after three consecutive deductions fail.

Of course, if investors decide to invest in this fund, they can stop selling or even redeem it. After redemption, they can buy other types of funds. Generally speaking, if they want to continue investing, they need to transfer the money to a debit account. If they don't need it, they can terminate it or even redeem it.
