Chinese Stock Screen Using Price Range, Turnover, and Weekly Momentum

Summary

This Chinese-language post describes a stock selection screen based on three market conditions: daily price amplitude above a threshold, turnover between specified bounds, and a weekly bullish signal. The rationale is that more active, volatile stocks may attract attention, while the weekly signal is intended to reflect improving sentiment. It includes indicator logic and illustrative code references, but the implementation details are not fully consistent: the sample code estimates turnover using recent volume rather than the stated turnover-rate field, and its weekly condition is represented through daily data.

The author warns that the screen ignores fundamentals and may miss longer-term market direction. The amplitude and activity filters may also be subjective or vulnerable to speculative trading. Suggested refinements include adding financial measures, combining indicators with weights, and considering other technical signals. No backtest results or evidence of improved returns are supplied, so the selection rationale should be treated as a hypothesis requiring careful implementation checks and testing.

Key ideas

• The screen combines a minimum price amplitude, a bounded turnover range, and a bullish weekly signal.
• Its rationale is to identify active stocks with improving technical behavior.
• The post acknowledges that the method omits fundamentals and may overlook longer-term trends.
• The sample code’s turnover estimate and daily-data implementation may not match the stated screening conditions.
• The author proposes adding fundamental and technical measures but provides no performance evidence.
