Chinese Stock Screen Using Amplitude, Opening Gain, and Turnover

Summary

This short-term stock screen selects Chinese equities using three conditions: daily amplitude above 1, the 9:25 price gain below 6%, and previous-day turnover above 60 million. The stated rationale is to find active, liquid stocks while avoiding stocks that have already risen sharply before the session. The article also gives example implementations using a charting formula and Python with market data from Tushare.

The post describes the method as simple and suitable for short-term trading, but provides no backtest, performance data, or detailed rules for entries, exits, and position sizing. It warns that the screen may encourage chasing rising stocks, produce unstable selections, and be affected by broader market conditions. It suggests adding technical and fundamental filters and explicit risk controls. The code examples are illustrative and rely on particular dates and data fields, so they do not establish that the screen is reliable or ready for live trading.

Key ideas

• The screen requires amplitude above 1, a 9:25 gain below 6%, and previous-day turnover above 60 million.
• The stated goal is to identify active stocks with sufficient liquidity while limiting pre-open gains.
• The article includes illustrative charting-formula and Python implementations.
• The method has no reported performance evidence and may produce unstable results or encourage chasing.
