Screening for Strong Recent Highs and Repeated Limit-Up Sessions

Summary

This post describes a stock screen that requires amplitude above 1%, a current high equal to the highest high over two days, and more than two limit-up sessions within the prior 10 days. The combination targets stocks with recent price movement, a short-term high, and repeated strong attention or demand. It sketches formula and Python-style implementation ideas, while leaving fundamental, industry, technical, and risk filters to be supplied by the user.

The author warns that emphasizing limit-up frequency and recent performance may encourage buying after sharp rises and selling into declines. The screen also ignores company fundamentals and longer-term market trends unless additional filters are added. The post offers no backtest, trade rules, or evidence that the conditions predict future returns. Its code is illustrative and platform-dependent, so key calculations and implementation details require verification before use.

Key ideas

• The screen selects for amplitude above 1%, a two-day highest high, and more than two limit-up sessions in 10 days.
• Repeated limit-up moves are used as a proxy for recent market attention.
• The post identifies chasing recent strength as a risk of the selection logic.
• It proposes adding fundamental, industry, technical, and risk controls without specifying them.
• The examples are not accompanied by backtest evidence or a complete trading plan.
