Mainboard Stock Screening with KDJ Crossovers and Daily Gains

Summary

This note describes a short-term mainboard stock screen combining daily price movement with a KDJ signal. It selects stocks whose intraday high-low range exceeds 1%, whose J line has just crossed above the D line, and whose daily gain exceeds 1%. The post offers indicator formula and Python examples as references for implementing the selection rules.

The rationale is that larger daily ranges may offer more opportunity, a fresh crossover may indicate improving momentum, and a daily gain may show recent demand. These are hypotheses rather than demonstrated results: the document provides no backtest or performance evidence. It warns that the screen omits company and industry fundamentals, that recent gains do not establish lasting trends, and that short-term picks may be volatile. It suggests adding fundamental and industry analysis, or adjusting the gain threshold, but does not test those changes.

Key ideas

• The screen combines an intraday range threshold, a fresh KDJ J-over-D crossover, and a daily gain threshold.
• The intended universe is mainboard stocks.
• The rationale relies on volatility and recent price strength as possible indicators of opportunity.
• The document provides implementation examples but no measured strategy performance.
• It cautions that short-term price signals omit fundamentals and may produce volatile selections.
