A Chinese Stock Screen Using Range, Morning-Star Pattern, and 9:25 Gain

Summary

The proposed Chinese-stock screen looks for daily amplitude above 1, a morning-star-like candlestick condition, and a 9:25 gain below 6%. The article presents the combination as a way to identify active stocks with a potentially bullish pattern while limiting stocks that have already risen sharply before the open. It recommends adding turnover or volume measures and other chart patterns to provide more information about capital flows and price structure.

The post includes indicator syntax and sample Python logic, but it supplies no backtest or performance evidence. The code’s morning-star checks are not a full, clearly documented definition of the classic pattern, and the 9:25 calculation and data sampling are difficult to reconcile with the stated screen. The article itself notes that an opening move alone omits other money-flow information and that a stock may already have passed its momentum peak. The rule should be treated as an unvalidated filter rather than a tested strategy.

Key ideas

• The screen combines amplitude above 1, a morning-star-like pattern, and a 9:25 gain below 6%.
• The article frames the candlestick condition as bullish and the opening-gain cap as a way to avoid already large pre-open rises.
• It suggests adding turnover, volume, and other chart patterns to refine selection.
• The article provides sample indicator and Python logic but no performance test.
• The pattern checks and opening-price calculations are not fully specified and may not implement the stated rule precisely.
