Stock Screening with Intraday Range and an Oversold KDJ Crossover

Summary

This stock-screening rule selects shares whose daily high-low range exceeds one percent, whose KDJ indicator has just formed a bullish crossover, and whose K value is below 20. The post interprets the range condition as evidence of substantial volatility, the crossover as a possible improvement in momentum, and the low K reading as an oversold state that could precede a rebound. It presents the combined conditions as a way to create a candidate investment pool, with example indicator formulas and a Python implementation reference.

The post warns that this technical screen omits company fundamentals, that KDJ signals can lag, and that an oversold reading may accompany further declines rather than a rebound. It suggests adding fundamental measures and other indicators, and adjusting the rules as market conditions change. No backtest or performance evidence is provided. The examples explain how to express the screen, but the page does not establish that the conditions predict profitable trades; indicator definitions and implementation details should also be checked before use.

Key ideas

• The screen requires a daily high-low range greater than one percent, a newly formed KDJ bullish crossover, and K below 20.
• The post interprets the conditions as combining volatility, a momentum turn, and an oversold reading.
• The author cautions that KDJ can lag and that oversold prices may continue falling.
• The rule does not consider company fundamentals, and the post suggests adding fundamental and technical measures.
• No backtest results are given to establish the screen’s profitability.
