Short-Term Stock Screen Using Limit-Ups and a Morning-Star Pattern

Summary

This note describes a short-term Chinese stock screen using daily amplitude above 1, a named morning-star pattern, and more than two limit-up days within ten days. It frames large price swings and repeated limit-ups as signs of strong near-term price action. The post includes formula and Python examples intended to identify candidates from recent daily prices, with the Python description also referring to turnover and MACD conditions.

No backtest or measured results support the claim that these conditions offer short-term opportunity. The post recognizes that repeated limit-ups can expose traders to crowded exits, speculation, and abrupt reversals, and that technical filters omit company fundamentals and broader market risk. Its optimization suggestions include adding profitability and financial-health measures and checking trading volume and valuation. The snippets do not align cleanly with the headline rules: their thresholds and pattern logic differ in places, so implementation details need review before the screen could be evaluated reliably.

Key ideas

• The stated screen combines amplitude above 1, a morning-star pattern, and more than two limit-up days in a ten-day window.
• The author interprets repeated limit-ups and large swings as signs of short-term price strength.
• The post offers code examples but no backtest or performance evidence.
• It warns about crowded trading, speculative activity, reversals, and the omission of fundamental and market risks.
• The sample implementations contain conditions that differ from the headline screen and need validation.
