Chinese Stock Screen Combining Limit-Down Auctions and Shortening MACD Bars

Summary

This Chinese stock-screening idea combines three signals: a strong volume-to-float-market-cap ratio, a previous-day 9:15 auction match at the limit-down price, and shortening green MACD histogram bars on a 15-minute chart. The stated rationale is that a limit-down event can reflect weak sentiment or outflows, while contracting negative MACD bars may suggest that downward momentum is easing. Together, the conditions are presented as a way to find possible rebound candidates; the post does not provide performance data or evidence that the combination predicts reversals.

The author suggests experimenting with longer MACD periods and adding measures such as turnover or valuation ratios. Its proposed final screen mixes a 30-minute MACD condition with a suggestion to extend the interval to 60 minutes, leaving the exact timing specification unclear. The post also warns that prices may keep falling after a limit-down event and that any perceived undervaluation may take time to be recognized. These are screening criteria, not a tested trading system, and the document gives no entry, exit, or risk-sizing rules.

Key ideas

• The screen combines a previous-day limit-down auction match with shortening green MACD bars and a volume-based capital-strength measure.
• The MACD condition is framed as a possible sign that downside momentum is fading.
• The post suggests testing longer chart intervals and adding turnover or valuation measures.
• A limit-down stock may continue to fall, and a possible undervaluation may not lead to an immediate rebound.
• The document reports no backtest results and leaves the final MACD interval ambiguous.
