Screening Stocks for Reversal Patterns and Positive Auction Net Buying

Summary

This note proposes a Chinese equity screen requiring price amplitude above 1%, a reversal or engulfing-style pattern, and positive net buying attributed to major participants during the opening auction. It explains the signals as indicators of short-term movement and buying interest, and gives formula and Python examples that combine amplitude, a candlestick-pattern check, and a net-flow proxy. Candidates are ranked by market heat.

The article warns that short-term price signals can overlook a company's long-run value and that auction inflows may not reliably indicate favorable demand. It recommends combining technical signals with company profitability and industry analysis. The explanation does not define the reversal pattern consistently across its formula and code examples, nor does it provide data, backtest results, or evidence that the signals predict returns. The screen should therefore be read as a proposed filter rather than a validated strategy.

Key ideas

• The proposed screen combines amplitude above 1%, a reversal pattern, and positive opening-auction net buying.\nIts examples use technical indicators and a net-flow measure to filter and rank stocks.\nThe article cautions that short-term signals can overlook company fundamentals and long-term value.\nAuction buying flows may not reliably signal continued demand.\nNo empirical validation or performance results are included.
