Chinese Stock Screen Using Intraday Range, Limit-Up Patterns, and Recent Highs

Summary

This note describes a Chinese equities screening idea intended for use before 10 a.m. It combines a price-range threshold, exclusion of stocks marked ST, a five-day limit-up-related condition, and a recent-high filter. The article’s initial description specifies a two-day high, while its proposed refinement shifts to a longer-term high. Its sample Python logic uses a five-session closing-price maximum and compares the two-day and 21-day high-water marks; these implementations do not fully clarify the named “five-step limit-up” pattern.

The rationale is that range and limit-up behavior may identify active stocks, while a recent high may indicate short-term strength. The article cautions that the screen relies on technical data and may select volatile stocks; it suggests adding fundamental analysis and using a longer-term high condition. It supplies sample logic but reports no backtest, performance evidence, or detailed rules for validating the pattern. The criteria should therefore be treated as an illustrative screen rather than a demonstrated trading strategy.

Key ideas

• The screen combines price range, ST-status exclusion, a limit-up-related condition, and a recent-high test.
• The sample implementation uses five-session closing highs and compares two-session and 21-session highs.
• The article’s initial two-day-high description differs from its proposed longer-term-high refinement.
• The author warns that technical-only selection can expose traders to volatility and recommends adding fundamental analysis.
