Screening Stocks by Range, Institutional Flow, and Low KDJ Value

Summary

This stock screen combines three conditions: price amplitude above a threshold, positive institutional-flow activity, and a K value below a threshold from the KDJ indicator. The accompanying examples calculate amplitude from the high, low, and open, sum positive net fund amounts over a short lookback, and derive K from KDJ. The intended interpretation is that the range and flow conditions identify active stocks while a low K reading selects shares that may be oversold.

The document presents the conditions and sample formulas but offers no backtest, evidence of predictive value, or clear specification for consistent data sources and measurement periods. It warns that technical indicators can be unreliable and that the screen omits company fundamentals, industry context, and market cycles. It suggests adding financial and market factors and adapting criteria to conditions, but supplies no tested process for doing so.

Key ideas

• The screen requires amplitude above a threshold, positive institutional flow, and a low KDJ K value.
• The examples calculate amplitude from a bar's high, low, and open prices.
• A low KDJ K reading is treated as a possible oversold signal, not a guarantee of a rebound.
• The document reports no tested returns or evidence that the combined conditions predict performance.
• It recommends adding fundamental and industry analysis to address the limits of a technical-only screen.
