First of all, the money in the fund account will not automatically buy fund products, so you need to confirm it. The recent mercenary Jinbao has this automatic pooling account to buy fund products. This kind of automatic purchase behavior, the broker's explanation is to facilitate your idle funds to manage money. You can set up a trigger fund. The initial trigger fund is 200 yuan. That is, if it exceeds 200 yuan, it will automatically purchase the fund. You can turn this up and then it won't be like this. The buying time is 4 pm on the trading day. Unless you want to transfer money the next day, it won't affect you, and you can still get a little fund income. Note that the fund cannot be transferred to the bank card on the day of redemption.
