Fund fluctuation refers to the fluctuation range of the fund relative to the previous trading day, which is generally expressed as a percentage. Fluctuation (%) = (current net value-net value at the close of the previous trading day)/net value at the close of the previous trading day * 100%, and fluctuation is the performance of fund fluctuation.

A positive fund fluctuation means that the fund is rising on that day, while a negative fund fluctuation means that the fund is falling, and the fund fluctuation will be directly displayed without the need for investors to manually calculate.
