A-Share Screen for Wide Ranges, Limit-Down Opening Match, and Large-Order Flows

Summary

This proposed Chinese stock selection rule combines a daily amplitude threshold, a prior-day 9:15 matching price associated with a limit-down condition, and a ranking by large-order net volume. The article frames the combination as a way to consider price volatility, market sentiment, and capital flows, with the ranking intended to surface stocks attracting stronger large-order activity. It provides example platform formulas and Python-like code, including a requested top-N selection and a further sort by stock popularity. It reports no backtest, measured returns, or evidence that these conditions improve selection.

The article notes uncertainty from company fundamentals, financial data, market conditions, and trading decisions, and recommends incorporating broader economic and industry information. The timing and order-flow measures depend on platform-specific data definitions, and the sample implementation may require adaptation. The proposed conditions describe a short-term screening idea; they do not specify entry, exit, position sizing, or risk controls sufficient to define a complete trading strategy.

Key ideas

• The selection rule combines daily amplitude, a prior-day opening match condition, and large-order net-volume ranking.
• The article presents order-flow ranking as a way to identify stocks with stronger large-order activity.
• Its code examples are platform dependent and offered without performance evidence.
• The screen does not define complete trade management or risk controls.
