A-Share Screen Combining RSI, Price Decline, Flow Proxy, and P/E

Summary

This proposed A-share stock screen combines a 14-period RSI below 65, a condition involving daily percentage change multiplied by a five-day large-order net-flow measure, and a current low below the prior day's low. The author frames the falling-low condition as a way to identify stocks that might rebound after a decline, while acknowledging that prices may continue falling. A later version adds a trailing price-to-earnings ratio below 30 as a fundamental filter.

The document includes reference implementations for a charting formula and a Python workflow, but the Python flow estimates net volume from turnover and the sign of price changes rather than directly measuring super-large-order activity. It provides no backtest results or evidence of predictive power. It warns about short-term speculation and recommends considering valuation, industry conditions, and broader economic context; those additions still require testing and risk controls.

Key ideas

• The screen uses an RSI threshold and a lower current-day low as selection conditions.
• It combines percentage change with a five-day measure described as super-large-order net flow.
• The suggested refined screen adds a trailing price-to-earnings threshold below 30.
• The Python example approximates order flow using turnover and price-change direction.
• The document warns that a recent decline may continue rather than reverse.
