Volatility, Reversal, and Auction Turnover Stock Screen

Summary

This Chinese stock-selection idea combines three filters: daily amplitude above 1%, a reversal or engulfing-style pattern, and previous-day auction turnover above 0.26. The article treats auction turnover as an indicator of activity during the opening call auction, and combines it with price range and reversal behavior to seek active, volatile stocks. It includes sample indicator formulas and a Python sketch, though these examples do not establish that the conditions are implemented consistently or validated.

The article provides no backtest, selected-stock history, or performance results. It warns that volatile stocks may have small market capitalizations and weak liquidity, can be moved by individual traders, and may produce unstable selections. It proposes adding fundamental and technical measures and using risk controls such as stop losses. The reversal condition is not carefully specified in the prose, and the code and formulas should be checked against the intended pattern and data definitions before use.

Key ideas

• The screen requires amplitude above 1%, a reversal pattern, and prior-day auction turnover above 0.26.
• Auction turnover is presented as a measure of activity during the opening call auction.
• The article supplies formula and code examples but no performance evidence.
• High volatility and low liquidity can make selected stocks unstable and difficult to trade.
• The reversal definition and example implementations warrant validation before use.
