A-Share Breakout Screen Using Recent Limit-Ups and Volatility

Summary

This post proposes a Chinese A-share stock screen that combines daily price range, a recent limit-up event, exclusion of ST-designated stocks, and a condition it calls a five-stage limit-up method. The stated rationale is that larger daily movement may identify stocks capable of strong gains, a recent limit-up may indicate market interest, and the additional pattern filter may remove speculative names. It provides example indicator logic and a Python sketch for applying conditions to daily price data.

The screen is intended to create a watchlist rather than provide a complete trading system. The post offers no backtest, return series, benchmark, or risk analysis, and acknowledges that investor sentiment can change and that the pattern may have limited applicability. Its implementation examples also leave important details unclear, including how the recent-event window is applied and whether the coded conditions faithfully implement the prose. The stated suggestion to add valuation or financial measures is an idea for refinement, not evidence of improved results.

Key ideas

• The proposed screen combines daily range, a recent limit-up event, non-ST status, and a multi-stage price pattern.
• The author interprets volatility and prior limit-ups as signs of potential price movement and market attention.
• The selected stocks form a candidate pool; the post does not specify a complete entry, exit, or sizing plan.
• No performance test or risk statistics are presented.
• The prose and sample code leave ambiguities about the event window and pattern implementation.
