Chinese Stock Screen Combining a Morning-Star Pattern and Bollinger Bands

Summary

This technical screen for Chinese stocks combines an amplitude condition, a morning-star style candlestick check, and a close within a Bollinger Band range. The post includes example formulas and Python logic that also checks moving averages, MACD values, and turnover. In the Python example, the closing price must sit between the middle and upper Bollinger bands, while the candlestick check uses recent prices and candle shape. These details make the examples more specific than the broad strategy description.

The article notes that price patterns and band position do not account for company fundamentals, unexpected events, or uncertainty about the timing and extent of future moves. It suggests considering financial measures, liquidity, trading volume, and market interest. No backtest or evidence of predictive performance is supplied. There are inconsistencies between the written conditions and the sample formulas, including the Bollinger bounds in one formula, so implementations should be checked carefully before use.

Key ideas

• The screen combines an amplitude filter, a morning-star style pattern, and a Bollinger Band condition.
• The Python example adds turnover, moving-average, and MACD checks.
• The described Bollinger range places the close between the middle and upper bands.
• The post warns that technical conditions do not account for fundamentals or sudden events.
• No tested performance is shown, and the sample formulas contain inconsistencies that need review.
