Screening Shanghai-Listed Stocks by Range, Volume, Opening Gap, and Code

Summary

This short-term stock screen selects shares whose price range exceeds a threshold, whose reported volume exceeds 10,000 lots, that open above the prior close, and whose codes begin with 60. The document frames the range and volume conditions as signs of trading activity, while the opening gap is treated as a possible indication of upward opportunity. It includes an indicator formula and a Python example for filtering Shanghai-listed shares.

The article characterizes the approach as suitable for short-term and theme-focused trading, but provides no backtest, returns, or explicit exit and risk rules. Its code examples also do not clearly implement every stated condition consistently: the narrative includes a range test, while the Python filtering example emphasizes volume and opening price. The author warns that attention to market heat can expose the screen to sentiment and news shocks and omit company fundamentals. Suggested improvements include adding profitability, dividends, balance-sheet measures, and other technical indicators before making decisions.

Key ideas

• The stated screen combines price range, volume, an open above the prior close, and a Shanghai stock code prefix.\nThe article treats range and volume as proxies for active trading and the opening gap as a possible bullish signal.\nThe formula and Python example are provided as implementation references, though the examples do not align fully with every stated condition.\nThe strategy has no reported performance test or detailed trade management rules.\nThe author recommends adding fundamental and technical checks and accounting for sentiment and news risk.
