Screening Equities by Range, Large-Order Activity, and Market Capitalization

Summary

The post presents a Chinese equity screen combining daily price range, a ranking based on net large-order activity, and a minimum market-capitalization condition. Its stated rationale is to find stocks with notable volatility and trading activity while retaining larger companies. It includes references to implementing the conditions in a stock-selection platform and through a data API workflow.

The author notes that the screen relies on short-term price and trading signals and does not assess companies’ long-term fundamentals. The narrow criteria may also limit which stocks qualify. Suggested refinements include adding technical and fundamental factors, relaxing or changing the capitalization filter, and backtesting the resulting rules to examine stability. The post provides a screening concept and implementation examples, but no reported backtest results or evidence that the selected stocks outperform. Some example code and condition descriptions appear inconsistent, so the precise operational definition of the large-order ranking and capitalization threshold needs verification before use.

Key ideas

• The proposed screen combines price range, large-order net activity ranking, and a market-capitalization filter.
• The rationale is to select relatively active and volatile equities while applying a size constraint.
• The author cautions that the screen omits long-term fundamentals and may qualify too few stocks.
• Additional factors and backtesting are suggested, but the post reports no performance evidence.
• The examples contain ambiguities that should be resolved before implementing the stated conditions.
