Screening Stocks by Turnover, Reversal Patterns, and Auction Buying Flow

Summary

This Chinese-language post proposes a short-term stock screen combining turnover between 3% and 12%, a reversal or engulfing-style pattern, and auction-period buying attributed to large and very large orders. The stated flow threshold is more than 0.7 ten-million units of currency. The rationale is that turnover and reversal behavior may identify active stocks, while concentrated buying may help reveal market interest and changing sentiment. The post also includes formula and Python examples, though those examples do not clearly implement every stated condition: the Python uses minute bars and price movement filters, and does not explicitly calculate the stated turnover range or auction order categories.

The author warns that the screen may favor unstable short-term moves and that large-order activity can be distorted by sentiment or policy changes. Suggested additions include valuation and profitability checks and other market indicators. No backtest, performance statistics, or evidence of predictive power is presented, so the rules should be treated as an unvalidated screening idea.

Key ideas

• The proposed screen combines a turnover range, a reversal pattern, and auction-period large-order buying.
• The stated buying-flow threshold is above 0.7 ten-million currency units.
• The post frames order flow as a possible indicator of stock interest and market sentiment.
• Its sample code does not transparently implement all conditions in the written rule.
• The document reports no performance testing and notes short-term and flow-measurement risks.
