The advantage of the fixed investment of the fund is to buy more shares when the net value of the fund is low, and buy less shares when the net value of the fund is high, which reduces the cost of holding the fund and avoids the risks brought by the fluctuation of the net value. So it is very suitable for the fixed investment of stock funds and index funds.
I recommend two funds that I have decided to invest in: Huaxia CSI 300 and Huaxia Advantage Growth. I have invested in China for 4 years, and now I am making a profit. However, I invested in China Construction Bank, and the minimum requirement for each fund is 300 yuan. I don't know how much other banks require. You can also invest in fund management companies in official website and China.
Don't terminate and redeem it easily after the fixed investment, and try to stick to long-term investment (all can be redeemed when the stock market rises sharply).
