Screening Chinese Stocks by Price Range, Limit-Ups, and Recent Highs

Summary

This stock screen combines three price-action conditions: a daily high-low range above one percent, at least two sessions that meet a limit-up proxy during the prior 500 days, and a current high equal to the highest high across two days, with the prior day’s high above the one before it. The post presents these as filters intended to find volatile shares with prior strong advances and short-term upward momentum. It also mentions ranking candidates by a capital-strength measure.

The document gives indicator-style expressions and a sample Python workflow, but it does not provide a backtest, portfolio rules, transaction costs, or performance evidence. Its code’s range check uses an average range and close price in a way that appears inconsistent with the stated greater-than-one-percent condition, so the example may not implement the written screen faithfully. The author cautions that technical filters can omit market sentiment, capital flows, and fundamentals, and suggests adding other indicators or loosening the criteria. The screen is presented as a starting point, not a validated investment strategy.

Key ideas

• The proposed screen combines a daily price-range threshold, historical limit-up events, and a two-day high condition.
• The stated lookback for counting limit-up events is 500 days.
• The article suggests ranking selected stocks by capital strength.
• The sample code’s range calculation appears inconsistent with the written screening rule.
• The document offers no backtest evidence and warns that technical filters omit other factors.
