Screening for Three Consecutive Limit-Ups and High Price Ranges

Summary

This Chinese stock-screening proposal selects shares with a daily high-low range greater than 1 that had three consecutive limit-up sessions as of the previous day, while excluding the STAR Market. The article interprets the range as a sign of volatility and the streak as evidence of market attention, presenting the combination as a high-risk, high-return opportunity. It includes formula and Python examples, though the examples do not consistently implement the stated exchange exclusions or limit-up logic.

The article offers no backtest, return analysis, or evidence that the screen predicts continued gains. It acknowledges that the rules focus on price behavior and can ignore longer-term business fundamentals and market demand. Suggested refinements include adding fundamental, sector, and capital-flow analysis and checking for a strong rising trend. Those are recommendations rather than tested additions, so the screen is best understood as a speculative momentum filter with substantial validation needs.

Key ideas

• The proposed screen requires a high-low range greater than 1 and three consecutive limit-up sessions through the prior day.
• It excludes STAR Market stocks and treats the streak as a sign of attention and momentum.
• The article presents code examples but provides no backtest or performance evidence.
• Price-based rules can overlook company fundamentals and broader market conditions.
• The suggested fundamental, sector, and capital-flow checks are not evaluated in the document.
