If you want to buy funds in online banking, you must open a fund account at the bank counter before you can buy funds in online banking. It is best to consult the bank staff, especially for the first time to buy funds through online banking.
As for handling fees, funds with front-end fees have handling fees when buying, while funds with back-end fees have no handling fees when buying, but not all funds have back-end fees. Under normal circumstances, funds with long-term fixed investment are suitable for choosing funds with back-end fees, so there is no handling fee when buying every month, which can save a lot of handling fees in the long run. If it is a short-term investment, there is no need to choose a fund with back-end fees. Whether there are back-end fees is explained in the column of fund subscription fees.
