If the fund's fixed investment strategy is accurately used, it can help investors dilute costs and reduce investment risks. However, how to set the fixed investment time can depend on the market. If the market price is low or good, you can shorten the fixed investment time, and you can set it once a week to accumulate positions at a low level. If the market price is high and the market starts to fall, then the fixed investment time can be extended once a month or longer.

However, it should be noted that the fixed investment of the fund cannot be fixed every day, because if you buy it every day, not only can you not dilute the cost and reduce the risk, but you may also cause great losses.
