Chinese Stock Screening with Intraday Inflows and Large-Order Volume

Summary

The document describes a Chinese equity selection rule combining a daily range filter, afternoon large-order net inflow, and a score based on price change multiplied by a large-order volume measure. It ranks candidates by the resulting score and selects the stocks with the strongest gains. The accompanying indicator references describe how the range, inflow, and volume conditions are constructed, and example code sketches a process that scans listed stocks using daily data.

The author flags liquidity and sector effects, limited attention to company finances, and sensitivity of the multiplicative score to large moves in its inputs. Suggested refinements include weighting the measures and repeatedly testing the screening rule. However, the document reports no return series, benchmark comparison, or evidence that the screen predicts future performance. The sample code also appears schematic, with platform-specific functions and data assumptions that would need checking before use. The strategy should therefore be read as a proposed selection recipe, not a validated result.

Key ideas

• The screen combines a minimum daily range with an afternoon large-order inflow condition.
• A price-change measure multiplied by a large-order volume measure forms the ranking score.
• Candidates are ranked by the score, with stronger recent gainers preferred.
• The author warns that liquidity, sector effects, financial risks, and score sensitivity may affect results.
• The document suggests weighting factors and repeated testing but presents no performance evidence.
