Screening Chinese Stocks by Range, Prior Limit Status, and Auction Move

Summary

This stock selection method looks for shares with a daily price range above 1%, excludes shares that closed at the limit on the previous day, and requires the current session’s auction move to fall between -2% and 5%. The post presents the conditions as a buy signal and suggests that a non-limit prior session and moderate auction move may identify active stocks with room to rise.

The evidence is a rule description and example indicator and Python snippets; no backtest, performance figures, or validation are reported. The sample Python also contains apparent naming and data-flow inconsistencies, so it may not implement the stated screen reliably. The author notes that the method omits company fundamentals and that auction prices can reflect temporary sentiment and volatility. Suggested additions include fundamental filters and technical or fundamental context for the auction move, as well as stop levels. Holding duration is left to the user's risk and return preferences.

Key ideas

• The screen requires a daily price range above 1%.
• It excludes stocks that were limit-up or limit-down on the previous session.
• The current auction move must be between -2% and 5%.
• The post offers no performance evidence and warns that fundamentals and short-term auction volatility are omitted.
