Chinese Stock Screening with Amplitude, Main-Force Control, and Volume Ratio

Summary

This post describes a Chinese equity screen using daily price amplitude, a prior-day indicator described as main-force control, and a volume ratio bounded between 1.5 and 6. The author interprets the amplitude and volume conditions as signs of trading activity, and the control measure as an indication of major capital flows. A code example also filters for positive percentage change and sorts by market capitalization, though its implementation does not clearly reproduce every stated condition.

The post warns that relying on a small number of signals can concentrate holdings and make results depend too heavily on a single factor. It suggests incorporating company fundamentals, technical conditions, valuation, and risk controls. No backtest results, performance data, or detailed definitions of the indicators are supplied, so the screen is a rule proposal rather than evidence of a tested edge.

Key ideas

• The proposed screen combines price amplitude, a prior-day main-force control condition, and a volume ratio between 1.5 and 6.
• The accompanying code also filters for positive price change and sorts candidates by market capitalization.
• The post cautions that a narrow set of signals may create concentrated holdings and single-factor dependence.
• It recommends adding fundamental, valuation, market, and risk considerations.
• No performance results or validation are presented.
