Chinese Stock Screening with Intraday Flow and Price Activity

Summary

This Chinese A-share screening idea combines a daily price range above 1%, current trading volume above 10,000 lots, a high opening price, and net inflow from large orders in the afternoon. It presents the approach as a way to find actively traded, volatile stocks with positive same-day money flow, and includes a Python example intended to illustrate screening conditions.

The note warns that the filters may chase prices after a rise, overlook company fundamentals, and produce false signals when price movement or flow data are misread. It suggests adding company, sector, valuation, and technical factors, but provides no backtest, benchmark, holding period, exit rule, or evidence that the screen is profitable. The sample code’s data fields and conditions also do not map cleanly to every stated rule, so the implementation would need review before use. The idea is a short-term selection heuristic, not a validated trading system.

Key ideas

• The proposed screen combines price amplitude, trading volume, a high open, and afternoon large-order net inflow.
• It targets volatile and liquid Chinese stocks showing positive same-day flow.
• The document identifies risks from chasing momentum, ignoring fundamentals, and misreading market conditions.
• No backtest, benchmark, or complete entry and exit plan is supplied.
