Equity Screening with Price Range, Limit Status, and Rising KDJ

Summary

This technical stock screen selects shares with daily amplitude above 1, excludes stocks described as limit-up on the prior day, and requires the K value of the KDJ indicator to be rising. The author treats amplitude as a sign of market activity and a rising K value as a potential buy signal. Formula guidance and sample code are included, but the note reports no backtest, return series, or comparative evidence that the combination is predictive.

The approach focuses on price behavior and omits company quality, earnings, and valuation. The author cautions that KDJ can mislead when sentiment or volatility shifts, and suggests adding fundamental measures and setting stop-loss and take-profit levels. The prose and sample code are not fully aligned: the stated exclusion concerns prior-day limit-up stocks, while parts of the code appear to test price-range conditions on fetched data. The exact timing and implementation should therefore be clarified before the screen is used.

Key ideas

• The screen requires amplitude above 1, excludes prior-day limit-up stocks, and looks for a rising KDJ K value.
• The author interprets a rising K value as a possible buy signal, but supplies no evidence of profitability.
• The method omits fundamental company measures and may select low-quality stocks.
• KDJ signals can be distorted by changes in market sentiment and volatility.
• The note recommends combining technical and fundamental inputs and setting exit controls.
