Combining Morning Price Gaps, Recent Limit-Ups, and Moving-Average Alignment

Summary

This note proposes screening Chinese A-shares using three conditions: a 9:25 a.m. price change below 6%, more than two limit-up sessions in the previous ten days, and at least five moving averages meeting a stated alignment condition. It frames the moving-average filter as a way to identify agreement across short- and medium-term price trends, repeated limit-ups as a sign of attention and buying pressure, and the pre-open price constraint as a way to avoid especially large gaps. The article includes a brief code sketch illustrating the filters.

The note does not provide backtest results or other evidence that the combination predicts returns. It acknowledges sensitivity to moving-average choices, the possibility of excluding longer-term opportunities, and the risk that a modest pre-open move does not imply strong follow-through. The prose describes averages as overlapping, while its code expresses a strict descending ordering, so the implementation does not clearly match the stated condition. Parameters and definitions would need clarification and testing before practical use.

Key ideas

• The proposed screen combines morning price change, recent limit-up frequency, and moving-average alignment.
• The document interprets aligned averages as trend agreement and repeated limit-ups as evidence of attention.
• It warns that indicator parameters and market conditions affect the screen’s usefulness.
• A constrained morning gap may still be followed by weak price action.
• The code’s strict ordering of averages differs from the prose description of overlapping averages.
