Screening Stocks by Range, Volume, Opening Gap, and Prior-Day Low

Summary

This Chinese equities post describes a technical screen requiring a daily range above one percent, current volume above ten thousand lots, an open above the prior close, and a close above the previous day’s low. It presents the conditions as a way to find active stocks showing an upward price tendency and supplies example implementations for a screening formula and a Python data workflow. The Python example also retrieves valuation and return-on-equity fields and applies a market-capitalization filter, although the written core screen does not define those as required conditions.

The author cautions that the screen omits company fundamentals and broader market risks, and recommends combining technical measures with financial and economic context. No backtest, performance figures, or evidence of predictive power is included. The examples also do not fully clarify how all stated conditions are calculated in each implementation, so the screen should be treated as an outline rather than a validated strategy.

Key ideas

• The stated screen combines a range threshold, a volume threshold, a gap-up open, and a close above the prior day’s low.
• The post presents the conditions as filters for active stocks with a possible upward tendency.
• It recommends adding technical and fundamental context, including valuation and profitability measures.
• No backtest or performance evidence is supplied, and the code examples do not clearly validate the stated logic.
