Equity Screening with Rising Lows and Auction Turnover

Summary

This Chinese-language post describes a short- or medium-term stock screen using three conditions: amplitude above 1, a rising bottom pattern, and previous-day opening-auction turnover above 0.26. It presents the rules as a way to identify stocks with stable price movement and includes references to implementations in a charting formula and Python, plus ranking selected stocks by percentage change.

The post offers no backtest, return series, benchmark, or evidence that the screen predicts performance. It cautions that market conditions, data collection and calculation accuracy, and parameter choices can affect results. It suggests adding market-trend or fundamental inputs, such as market capitalization and financial data, and exploring machine-learning adjustments, but provides no evaluation of those proposals. The text also contains inconsistent implementation details, so the exact definitions of amplitude and rising bottom would need to be checked before reproducing the screen.

Key ideas

• The screen requires amplitude above 1, a rising-bottom pattern, and previous-day auction turnover above 0.26.
• The post frames the conditions as a stock-selection approach for short- or medium-term investors.
• It shows that the rules can be expressed in a charting formula or applied to tabular stock data.
• The post provides no performance test and flags market regime, data quality, and parameter selection as risks.
