Chinese A-Share Screening with Morning-Star and Opening-Gain Filters

Summary

This document describes a Chinese stock screen combining intraday amplitude above 1, a named morning-star candlestick condition, and a 9:25 price gain below 6%. It presents the combination as a way to find active stocks with potential upside while limiting exposure to sharp opening moves. The article also sketches a Python implementation using market data, daily bars, moving averages, and an intraday bar check.

The rationale and implementation have notable limitations. The article acknowledges that using only the 9:25 gain as a capital-flow proxy omits other flow measures, and that volatile or pattern-based candidates may have already missed a market move. Its code also introduces additional filters, including market capitalization and exchange-segment exclusions, and its morning-star function is a simplified rule set. No backtest results or performance evidence are supplied, so the proposed risk and return benefits are unverified.

Key ideas

• The screen combines amplitude, a morning-star pattern, and a cap on the 9:25 price gain.
• The article suggests adding turnover and trading volume to improve its capital-flow assessment.
• The Python example adds market-capitalization and market-segment filters beyond the headline criteria.
• The document provides no backtest evidence, and its pattern and opening-price checks are simplified.
