Chinese Stock Screen Combining Intraday Flow, Amplitude, and Valuation

Summary

This stock screen combines a daily price-movement condition, afternoon large-order net inflow, and valuation filters for Shenzhen main-board shares. It selects stocks within stated price-to-earnings and price-to-book ranges, then proposes checking company fundamentals and broader market conditions before investing. The article provides indicator formulas and sample Python-style logic intended to retrieve financial and price data and apply the filters.

The author advises managing risk after selection, including through stop-loss and take-profit rules, and cautions that valuation cutoffs are subjective and may not reflect company fundamentals or macro conditions. The screen is a candidate-generation method, not a complete tested portfolio strategy: the document provides no backtest results, definitions or validation of the large-order flow proxy, or evidence that the criteria predict returns. Its sample code also relies on data fields and functions whose availability and alignment would need verification before use.
