Chinese Stock Screen Using Intraday Range, KDJ, and Recent Price Highs

Summary

This Chinese stock-selection post describes filtering for non-ST shares before 10 a.m. with an intraday range condition, a recent closing-price high, and a rising KDJ K value. It also refers to a “five-step limit-up” method and mentions circulating market capitalization as a possible constraint, although the final stated screen and sample formulas do not clearly define all of these elements. The supplied formula checks whether the close equals its five-session maximum and whether K is increasing.

The article gives sample screening logic and Python-style calculations, but no backtest, performance statistics, or evidence that the conditions generate an edge. There is also a potential mismatch between the prose’s range threshold and the sample code, which compares an absolute price difference with one rather than clearly expressing a percentage. The author notes that activity and chart patterns omit company fundamentals, and that KDJ can lag or give false signals; suggested refinements include other indicators and company or industry analysis.

Key ideas

• The proposed screen combines non-ST status, a range filter, a recent closing-price high, and a rising KDJ K value.
• The text mentions market capitalization constraints, but does not consistently specify them in the final logic.
• The sample code and prose appear to express the range threshold differently.
• No performance evidence is presented, and the post flags technical-signal and fundamentals risks.
