A-Share Screen Using Intraday Range and a KDJ Bullish Cross

Summary

This Chinese-language post describes a stock-selection screen for shares whose codes begin with 60, whose daily high-to-low range exceeds one percent of the opening price, and where the KDJ indicator has just formed a bullish cross. The post explains the range filter as a way to find more volatile stocks and treats the KDJ cross as a possible sign of rising prices. It also provides formula and Python examples for applying the filters, then ranks candidates using a measure based on the stock’s position relative to its recent 50-period high-low range.

The post cautions that KDJ reflects past price action and may not predict future movement, and that greater range can bring greater risk without guaranteeing greater profit potential. It suggests combining technical signals with other indicators and considering company fundamentals. No backtest results, execution assumptions, or evidence of predictive performance are supplied. The screen is therefore a candidate-generation rule, not a demonstrated trading strategy; the post’s proposed ranking and filters require independent validation and careful treatment of data timing.

Key ideas

• The screen selects stocks with codes beginning in 60 and a high-to-low range greater than one percent of the open.
• A bullish KDJ cross is required as an additional entry condition.
• Candidates are ranked by a measure using the recent 50-period high, low, and close.
• The post warns that past indicator readings may not forecast future prices and that high range also means higher risk.
• No backtest or performance evidence is provided, so the screen’s predictive value remains unestablished.
