Screen Chinese Stocks for Trading Range, Limit-Ups, and Market Heat

Summary

This stock screen combines three filters: daily trading range above one percent, at least two limit-up events during the past 500 days, and ranking by a heat measure from highest to lowest. The accompanying rationale treats a larger range as a sign of trading activity and limit-up history as evidence of strong recent attention or price action. Its example implementation adds a large-order buying-versus-selling condition and estimates heat using trading volume and price, then keeps a ranked subset of candidates.

The article warns that attention can reflect sentiment or manipulation, and that a limit-up count can exclude stocks with other forms of strength. It suggests adding company fundamentals and business context, and considering measures such as price change and turnover. These are screening ideas rather than a tested trading system: the article provides no return, risk, or benchmark results. Its code and indicator descriptions may not implement every stated condition consistently, so the screen’s definitions and data handling would need validation before use.

Key ideas

• The proposed screen requires a trading range above one percent and at least two limit-up events in a 500-day window.
• Eligible stocks are ranked by a market-heat measure, which the example approximates with volume and price.
• The article cautions that heat can reflect sentiment or manipulation rather than business quality.
• It recommends adding fundamentals and other market measures instead of relying only on limit-up frequency.
• The article offers no backtest evidence, and the example implementation may not match every stated rule.
