A-Share Screen Using Daily Range, Turnover, and a Morning-Star Signal

Summary

This A-share screening idea combines a daily amplitude threshold, a turnover-rate band, and a candlestick condition described as a morning-star signal. The stated rationale is to find stocks with notable price movement and active trading, then use the pattern as a possible sign of a near-term reversal. The document gives an indicator expression and sample Python code, but the expression’s conditions do not clearly define a conventional multi-session morning-star pattern, and the sample implementation does not appear to match every stated screening criterion.

The article offers no historical test, performance evidence, or detailed rules for handling trade entry, exits, and position sizing. It cautions that technical signals are subjective and should be considered alongside fundamentals, and suggests adding other indicators or stricter filters. The strategy is therefore best understood as an informal screening recipe rather than a validated forecast of next-day returns; its thresholds and pattern logic would need precise specification and independent testing before use.

Key ideas

• The screen combines daily amplitude above its threshold with turnover between the stated lower and upper bounds.
• A candlestick condition labeled as a morning-star signal is intended to identify a possible reversal.
• The article supplies indicator and Python examples, but their logic may not fully align with the written rules.
• It recommends considering fundamentals and other indicators because technical patterns can be subjective and risky.
