This fixed investment method of regular and variable amounts is very scientific.

The principle is to compare the stock market trend with its selected moving average to see how much it deviates from the long-term average.

To put it simply, the deeper the decline, the higher the fixed investment amount will be.

The greater the increase, the smaller the fixed investment amount will be.

It is conducive to the accumulation of more advantageous low costs in long-term fixed investment.

I chose CSI 300, 120-day moving average, and 10% low.

This means comparing the CSI 300 Index with the 120-day moving average of the CSI 300 Index, and determining whether the fixed investment is more or less than the benchmark based on the size of the deviation.

The amplification factor of 10% is the magnitude of the increment or decrement.

10% is the lowest.
