Chinese Stock Screen Using Amplitude and a Morning Star Pattern

Summary

This Chinese-language article outlines a stock-selection screen that looks for shares with daily amplitude above 1%, excludes stocks that hit the daily limit on the previous session, and uses a morning star candlestick pattern as a further filter. It frames the pattern as a possible signal of an upward reversal and suggests adding technical and fundamental measures, such as KDJ, to broaden the analysis.

The article warns that the conditions may return few stocks and may not capture current market themes. It includes a Python example that retrieves Chinese stock data and evaluates price bars, but the code’s pattern check appears to append symbols when the morning-star result is zero, which may invert the stated selection rule. It provides no backtest results, transaction rules, or evidence that the pattern predicts returns. The screen is therefore illustrative and requires code review and empirical validation before use.

Key ideas

• The proposed screen combines amplitude above 1%, no prior-session limit-up, and a morning star pattern.
• The pattern is presented as a possible upward-reversal filter.
• The article warns that strict filters can produce too few candidates and limited market coverage.
• It suggests combining technical and fundamental measures to expand the analysis.
• The sample code’s zero-value pattern condition appears inconsistent with the stated intent and should be checked.
