Screening Chinese Stocks for Trading Activity and Large-Order Inflows

Summary

This stock-selection idea screens for shares with relatively large price movement and trading volume, a higher opening price, and specified order-flow conditions during the auction. It treats these criteria as signs of active trading and short-term buying interest, with particular weight on the combined volume of large and extra-large orders. The document also gives example indicator conditions and a Python outline for filtering a stock list.

The approach is framed as a short-term flow and activity screen, not a complete investment method. The article warns that large-order flows can reverse quickly and that order-flow measures alone omit fundamentals and broader market influences. It suggests combining the screen with valuation, company size, sector rotation, and macroeconomic information, but does not provide evidence from a backtest or live results. The formula and code descriptions also differ in how they express some selection conditions, so implementation details would need to be checked against the intended data fields and units.

Key ideas

• The screen combines price movement, volume, opening-price behavior, and auction order-flow criteria.
• Large-order buying is treated as a short-term indicator of activity and possible fund inflow.
• The article warns that order flows can reverse and that flow data alone does not capture fundamentals or broader conditions.
• It proposes adding valuation, company size, sector rotation, and macroeconomic factors.
• The document provides example logic but no performance evidence, and some formula and code conditions differ.
