A-Share Stock Screen Using Range, Price Shape, and Turnover

Summary

This Chinese-language post describes a short-term A-share screening rule based on three filters: daily price amplitude of at least one percent, a price level within ten percent of the higher of the five- and twenty-day moving averages, and a turnover condition expressed as a range from three to twelve percent. The “arc” criterion is implemented as a distance from that moving-average reference, while the turnover calculation uses recent volume data as a proxy. The post supplies formula and Python examples for applying the conditions.

The rationale is to find stocks with some trading activity and relatively moderate movement around moving averages. The post presents no backtest, sample dates, benchmark, or return evidence. It warns that the screen ignores fundamentals and may select poor-quality stocks, and suggests adding indicators, fundamental filters, or capital-flow information. The example should be treated as a screening idea rather than a validated strategy; its turnover proxy and data handling may not correspond to standard exchange turnover calculations, and no entry, exit, or risk rules are specified.

Key ideas

• The screen combines a minimum daily range, proximity to short moving averages, and a turnover band.
• The post frames the filters as a way to find moderately active stocks for short-term consideration.
• Formula and Python examples show how the conditions can be applied to stock data.
• No historical performance evidence or complete trading rules are provided.
• The author cautions that technical filters alone do not account for company fundamentals.
