Stock Screening by Intraday Range, Auction Value, and KDJ Momentum

Summary

This Chinese-language stock screen combines an amplitude threshold above 1, a ranking among the five highest stocks by the day’s auction amount, and a rising K value from the KDJ indicator. Its rationale is to find stocks with larger price movement and auction activity, then use the KDJ signal as an additional technical filter. The note gives indicative formula and Python-style examples and excludes stocks with no opening price in its sample outline.

The author warns that the screen neglects company fundamentals and that KDJ can lag, producing missed or false signals. Suggested refinements include adding other indicators, fundamental analysis, and position risk controls. The document offers no backtest, return figures, benchmark, or clear operational details for calculating the auction ranking and KDJ conditions; its examples should therefore be treated as an outline of a screening idea rather than validated evidence of an edge.

Key ideas

• The screen uses amplitude above 1 and ranks stocks by the day’s auction amount.
• It further requires the K value of KDJ to be rising.
• The note warns that the approach ignores fundamentals and uses a lagging indicator.
• It suggests combining technical signals with fundamentals and risk controls.
• No backtest or performance evidence is provided.
