A Chinese Stock Screen Using RSI, Listing Age, and Limit-Up History

Summary

This Chinese A-share screening idea combines a 14-period RSI threshold with listing age and recent limit-up activity. It seeks stocks with RSI at or below 65, more than one year since listing, and at least two limit-up events within a 500-day window. The stated rationale is to combine a technical condition with a minimum operating history and evidence of prior market attention. The article also offers sample formula and Python implementation references, but does not report a backtest, returns, or comparative evidence for the screen.

The source flags risks from relying on a small set of criteria, including attention driven by temporary catalysts and the possibility that limit-up rules make buying or selling difficult. It suggests adding measures such as volume and valuation, checking data quality, and evaluating parameters through backtesting and live trials. The provided formula and Python logic appear inconsistent with the stated 500-day count and age condition, so implementation details require verification before use. The screen is a candidate selection heuristic, not a demonstrated trading strategy.

Key ideas

• The screen combines an RSI ceiling of 65, a listing history longer than one year, and at least two limit-up events within 500 days.
• The proposed rationale is to pair a technical filter with listing history and evidence of past market attention.
• The article gives formula and Python references but reports no performance results or backtest evidence.
• Temporary catalysts can fade, and price-limit rules can restrict trade execution.
• The implementation examples should be checked because they do not clearly match all stated screening conditions.
