For daily investment, it is a daily fixed investment, suitable for investors with light fixed investment. For example, there may not be a lot of idle funds every month, but you don't necessarily know where to spend them, so you invest every day, so that while emptying the savings fund, every little makes a mickle.

Daily fixed investment is the best way to return funds in the short term. For example, if you decide to invest in a securities company every day, and one of them decides to invest in the lowest point of the securities company, then you may lose more than 20%, but once you rebound continuously, you will quickly return to your capital. Therefore, I suggest investing in funds with large fluctuations, but there is a premise that your bullets are infinite.
