Screening Chinese Stocks with Volatility, Volume, and Bollinger Bands

Summary

This note describes a Chinese equity screen combining price movement, trading activity, an opening gap, and Bollinger Band position. It selects stocks with an amplitude above 1, current volume above 10,000 lots, a higher open, and a close between the middle and upper Bollinger Bands. The article frames the criteria as a way to find active stocks with some upward momentum while avoiding closes above the upper band.

It provides indicator references and a Python sketch, but no backtest results or performance evidence. The code and prose do not fully align: the example checks maximum historical volume and opening price versus the low, rather than directly implementing every stated condition. The article also notes that the screen omits company fundamentals and capital flows, can be exposed to market noise, and relies on a lagging technical indicator. It suggests adding fundamental, industry, and flow information before using the candidates.

Key ideas

• The screen combines amplitude, current volume, a higher open, and Bollinger Band position.
• It selects closes above the middle band and below the upper band.
• The article provides no performance evidence, and its code only partly matches the written rules.
• Fundamental conditions, industry context, and capital flows are suggested as additional filters.
