There is no such thing. Judging from the fixed investment cycle of the fund, there is almost no difference between the fixed investment of days, weeks and months.

The fixed investment of the fund is to dilute the cost of entering the fund every time. Because the amount of funds invested in each investment is relatively small, and the average cost is not large, the frequency of investment depends entirely on the size of investment funds. The income of the fixed investment fund mainly depends on the rising space of the fund, and whether to choose to take profit after profit, the frequency of discussing the fixed investment cycle is of little significance.
