Screening Stocks for High Intraday Range, Large-Order Activity, and Gap-Ups

Summary

This Chinese-language note describes a short-term stock screen combining an intraday price range above a threshold, strong large-order net activity, current trading volume above a threshold, and an opening price above the prior close. It presents these as signs of volatility, active trading, and optimistic market sentiment, then suggests reviewing fundamentals and broader market conditions as additional filters.

The document gives illustrative indicator logic and sample Python screening steps, but the implementation does not cleanly match every stated condition: it uses turnover rate as a proxy for large-order activity and its volume checks differ across examples. It provides no performance results or validation. The approach focuses on short-term price and volume behavior, so it may select overheated stocks and does not assess long-term business quality; the conditions and data definitions would need careful review before use.

Key ideas

• The screen combines a large intraday range, elevated trading activity, and a gap-up open.
• The article treats these conditions as signs of volatility and short-term market interest.
• It recommends adding fundamental analysis and market trend context to refine selections.
• The examples use inconsistent proxies for large-order activity and volume, and no backtest evidence is supplied.
