A-Share Screening with Moving-Average Convergence and Recent Limit-Ups

Summary

This Chinese stock-screening post proposes selecting A-shares with at least five converging moving averages, a limit-up day within the prior 25 days, and a 9:25 auction gain below 6%. It presents the combination as a way to find stocks with aligned trends and recent buying strength. The post then revises its suggested thresholds: at least three converging averages, a limit-up within 20 days, and an auction gain below 5%. These are presented as a proposed final screen, not as findings from a tested strategy.

The accompanying Python example does not faithfully implement the full screen: it uses equality among five moving averages and an intraday price-change range instead of checking the auction move and recent limit-up condition. It also contains apparent syntax and data-handling problems. The post cautions that too many or slow moving averages can complicate or delay signals and that loose thresholds can produce frequent selections. It provides no backtest results or evidence that the rules are profitable.

Key ideas

• The initial screen combines five converging moving averages, a limit-up within 25 days, and a 9:25 gain below 6%.
• The post later proposes a revised screen using three converging averages, a limit-up within 20 days, and a 9:25 gain below 5%.
• The stated rationale is to combine trend alignment with evidence of recent upward momentum.
• The accompanying Python example does not implement all of the described filters consistently.
• No performance evidence or backtest results are provided.
