A Chinese Stock Screen Using Range, Price, and Morning Star Filters

Summary

The post outlines a Chinese equity screening idea combining daily price range, a low share-price threshold, and recognition of a Morning Star candlestick pattern. Its example implementations also apply a Bollinger-band closing-price condition, then show selecting matching stocks and sorting by trading volume. These elements describe a technical screen, though the stated rule and the example code do not align perfectly: the post first refers to a K-line condition, while its examples impose a closing-price cutoff and use differing amplitude calculations.

The author warns that technical-only screening can miss or misclassify candidates and suggests combining chart signals with other indicators and company or industry information. No backtest, benchmark, transaction-cost analysis, or performance evidence is supplied, so the post does not establish predictive value or profitability. The screening rules are an illustrative starting point, and the discrepancies and unspecified implementation details would need to be resolved before evaluation.

Key ideas

• The proposed screen combines stock price range, a price ceiling, and a Morning Star candlestick pattern.
• The example formulas add a Bollinger-band condition and sort selected stocks by volume.
• The written rule and example implementations contain differences in how the filters are defined.
• The post cautions that technical-only screening can produce missed or incorrect selections.
• No backtest or performance evidence is provided.
