I tried an improved dollar-cost averaging method, and it's quite interesting. The basic idea is still to buy a fixed amount, but with a bit of flexibility—keeping an eye on the moving average.

Once the price falls below the moving average, I increase the investment—perhaps 1300 yuan that month; conversely, if the price rises too sharply, I pull back and might invest only 700 yuan. It seems simple, but this approach actually automatically captures low points.

Backtest data is quite intriguing: this method has over a 60% chance of outperforming regular dollar-cost averaging. It maintains discipline while leveraging the mean reversion characteristic to buy low and sell high within market swings. Instead of being completely passive, it's better to leave some room for proactive adjustments.
