Screening Stocks by Intraday Activity, Opening Strength, and Recent Returns

Summary

This Chinese-equity screening recipe filters for stocks with an amplitude above one, current volume above ten thousand lots, a higher open, and a positive ten-day gain below thirty-five percent. The article interprets amplitude and volume as signs of trading activity, the higher open as a possible sign of strength, and the bounded recent return as a way to find stocks with upward potential. It suggests supplementing these conditions with company fundamentals, financial data, industry trends, and broader market risk.

The article provides indicator and Python references, but the implementation details are not fully consistent: the narrative describes amplitude and current volume, while the sample code checks different volume and price conditions. No backtest results or evidence of predictive performance are reported. The author also notes that the screen largely ignores fundamentals, sector context, policy, and market-wide risk, so it should be treated as a basic candidate filter rather than a complete trading strategy.

Key ideas

• The proposed screen combines price amplitude, current trading volume, opening strength, and a bounded positive ten-day return.
• The author uses activity and recent price behavior as proxies for potential short-term strength.
• The article recommends adding fundamental, industry, financial, and market-risk filters.
• Its sample code does not clearly match all of the stated screening conditions.
• No performance results are supplied, and the screen is not a complete trading system.
