Changing the bank card will affect the funds in and out of the fund account, but investors can change the bank card bound to the fund account after changing the card (which can be bound by the fund trading software). Generally, after changing the bank card, the card number will change and need to be re-bound. If investors buy funds on the banking platform, they generally do not need to rebind, and investors can trade directly.

Investors changing bank cards will not affect investors' income, but will only affect the inflow and outflow of funds, because the fund will generate profits and losses during trading hours. When the fund price rises, investors gain, while the fund price falls, investors lose.

Investors should pay attention to some fund trading software and only change their bank cards during trading hours (depending on each software). Trading hours are from Monday to Friday at 9: 30am-11:30am, and in the afternoon13: 00pm-15: 00pm. Trading is not allowed on legal holidays.
