Screening Stocks by Range, Main-Force Control, and Auction Turnover

Summary

The article proposes a Chinese equity screening rule using three conditions: a prior-day price range above a threshold, a positive reading for a “main force control” measure, and prior-day auction turnover above a stated cutoff. It presents the combination as a way to identify stocks with price activity and liquidity, and gives indicator references and illustrative code for implementing the filters. The article also suggests adding fundamental and broader market conditions or loosening the turnover constraint when adapting the screen.

The rationale is asserted rather than demonstrated: no backtest results, selection statistics, or evidence that the indicators predict returns are provided. The “main force” concept and auction-turnover calculation are not fully validated or explained, and the code is labeled as a reference, with some platform-specific notation that may require translation before use. The article itself notes that the screen omits company fundamentals and that a turnover threshold may exclude less liquid names. It describes a candidate selection rule, not a complete entry, exit, or risk-management strategy.

Key ideas

• The proposed equity screen combines price range, a positive main-force measure, and prior-day auction turnover.
• The turnover condition is presented as a way to favor more liquid stocks.
• The article suggests combining the technical filters with fundamentals or market conditions.
• No return testing is supplied, and the indicator definitions and code may need platform-specific validation.
