A-Share Screening with Morning Stars, Range, and KDJ Crossovers

Summary

This note describes a Chinese stock screen combining a morning-star candlestick pattern, a daily price range threshold, and a newly formed KDJ bullish crossover. Its indicator reference further conditions the crossover on a low prior J reading. The accompanying Python example checks recent candle direction and range alongside KDJ values, then collects matching listed shares while excluding one market segment.

The document explains the intuition that a large range may identify active stocks, a morning star may suggest a reversal, and a KDJ crossover from a low level may indicate a possible rebound. It offers no backtest, performance statistics, or validation of these assumptions. The text itself cautions that technical signals can be unstable and that historical price behavior does not ensure future results; it suggests adding industry, sentiment, and fundamental information. The code's candle checks are only a rough proxy for the named pattern, and the screen's return potential is asserted rather than demonstrated.

Key ideas

• The screen combines a morning-star pattern, a price-range condition, and a recent bullish KDJ crossover.
• A low prior J value is included as an additional filter in the indicator reference.
• The Python example uses candle direction and range checks as proxies for the stated chart conditions.
• The document provides no empirical performance evidence and cautions that technical signals may fail.
• Adding industry, sentiment, and fundamental measures is suggested as a possible refinement.
