Chinese Stock Screen Using Volatility, Current Volume, and Auction Activity

Summary

This Chinese equity screen looks for stocks with amplitude above 1, current volume above 10,000 lots, a higher open, and a measure combining the previous day’s turnover rate with the ratio of today’s auction volume to yesterday’s volume between 0.5 and 2. The stated rationale is to focus on liquid, actively traded shares with strong short-term market interest while filtering the auction-volume signal.

The article includes sample Python-style selection logic and recommends considering company fundamentals and other stock characteristics alongside technical conditions. It does not provide backtest results or evidence that the criteria produce positive returns. The source also warns that short-term price and volume filters can overlook business quality and expose traders to risks from large price swings. The screen is therefore a descriptive trading idea, not a demonstrated strategy, and implementation details should be checked against the written conditions before use.

Key ideas

• The screen combines price amplitude, current trading volume, a higher open, and a bounded auction-volume ratio.
• The author interprets these conditions as signs of liquidity and short-term market interest.
• The sample selection logic should be checked against the written criteria because the document does not establish that they are implemented identically.
• The article provides no performance testing and notes that the screen omits fundamental analysis.
