Filtering Chinese Stocks by Volatility, Large Gains, and K-Line Conditions

Summary

This Chinese-language post proposes an equity screen combining a large daily trading range, at least one unusually strong daily gain during a recent lookback, and a low K-line indicator reading. It describes K as a measure derived from closing prices relative to highs and lows, and presents indicator and Python examples for combining the conditions and ranking candidates by trading volume. The stated aim is to narrow the candidate list with a price-pattern filter.

The post cautions that the screen omits company fundamentals and industry characteristics, may be overly restrictive, and relies on a technical condition that can make results uncertain. It suggests adding company and market data, considering macroeconomic influences, and relaxing the filters. The examples do not provide a backtest or evidence of returns, and the indicator conditions shown in the reference formulas do not consistently match the written rule, so implementation details should be checked before use.

Key ideas

• The screen combines a large price range with a strong daily gain in a recent window and a K-line filter.
• The post provides example formulas and Python-style screening logic.
• It warns that the rules omit fundamentals, industry context, and broader market conditions.
• No performance test is supplied, and the sample conditions appear inconsistent with the stated K-line threshold.
