A Chinese Stock Screen Using Price Amplitude and a Five-Day Range

Summary

This Chinese-language post describes a stock-selection rule combining price amplitude above one, a rounded or arc-like price pattern, and a stock code beginning with 60. It frames amplitude as a way to find more active shares and the arc-shaped condition as a way to favor smoother movement. A formula reference defines the shape condition using the prior close’s position within the five-day high-low range, while the code prefix restricts the universe to Shanghai-listed shares.

The post offers no backtest results or evidence that these filters improve returns. It warns that technical signals can lag and that relying on them alone omits company fundamentals and industry context. It also acknowledges that restricting the universe by code excludes other shares. The proposed improvements are to add fundamental and industry analysis, consider a broader stock universe and short-term strategies, and adjust the indicators. These suggestions are qualitative; no parameters, validation process, or risk controls are provided.
