A-Share Stock Screen Using Turnover, KDJ Growth, and Large-Order Flow

Summary

This Chinese-language post proposes screening A-share stocks for turnover between 3% and 12%, a rising KDJ K value, and large-order net volume above 0.05 for at least three consecutive days. It presents turnover as a filter for moderate trading activity, KDJ growth as a positive technical signal, and persistent large-order flow as a possible indication of liquidity or buying interest.

The post provides formula and Python examples, then cautions that large-order activity can reflect short-term or unusual behavior whose cause is unknown. It suggests combining the screen with financial and market-performance factors and diversifying risk. The examples do not provide backtest results or evidence of predictive performance. Their details also do not align perfectly with the stated rule: the formula includes an alternative that can use fewer consecutive observations, while the Python example tests a rolling three-day ratio and has a misspelled column reference. Treat the screen as a proposed filter requiring implementation checks and validation, not as a demonstrated strategy.

Key ideas

• The proposed screen combines turnover between 3% and 12% with an increasing KDJ K value.
• It also seeks stocks with large-order net volume above 0.05 over consecutive days.
• The post treats turnover as a measure of trading activity and order flow as a possible sign of buying interest.
• The author warns that large-order activity may have short-term or unusual causes.
• The examples contain differences from the stated rule and provide no performance evidence.
