A Stock Screen Using Opening Gain, Price, and Intraday Range Filters

Summary

This post describes a simple short-term stock screen based on three conditions: intraday range greater than 1%, a closing price of 18.5 yuan, and an opening gain below 6% at 9:25. It proposes sorting qualifying stocks by turnover value. The author frames the filters as a way to find shares with some movement and a relatively modest opening rise, for possible short-term consideration. The post also gives formula and Python-style implementation references, though its example data date and exact field handling do not fully align with the stated 9:25 screening concept.

The article acknowledges that a few price filters can miss candidates and overlook company fundamentals or material news. It suggests adding valuation measures, trend and volatility checks, and fundamental or news analysis. No backtest, selected-stock list, or return evidence is provided, so the screen should be understood as a heuristic rather than a tested strategy. Price and opening conditions alone do not specify entry timing, exits, or risk limits.

Key ideas

• The screen filters for range above 1%, a closing price of 18.5 yuan, and an opening gain below 6%.
• Qualifying shares are intended to be ranked by turnover value.
• The post presents the screen as a possible short-term selection tool, not a complete trading system.
• The author notes that the few filters can miss relevant fundamentals and company news.
• No backtest or return evidence is supplied, and trade management rules are unspecified.
