A Chinese Stock Screen Using RSI, Order-Book Imbalance, and Recent Limit-Ups

Summary

The article proposes a short-term Chinese equity screen requiring a 14-period RSI below 65, displayed best-bid volume greater than best-ask volume, and at least one limit-up event during roughly the prior month. It frames the combination as a way to find stocks with supportive near-term conditions: RSI below the threshold, demand apparently stronger than supply at the top of the order book, and a recent sharp upward move. The article also includes example indicator and data-processing snippets, though its descriptions and sample conditions are not fully consistent: the prose says one recent limit-up, while examples refer to counts greater than one and use a price-change threshold.

No backtest results or measured returns are provided, so the selection idea is not validated by evidence in the text. The author notes that the screen omits fundamentals and focuses on short-term conditions, leaving it exposed to market disruptions and weak longer-term business prospects. Suggested improvements include adding fundamental or other technical filters and stronger risk controls. Signal definitions, execution timing, and handling of price-limit rules would need clarification before evaluating or using the approach.

Key ideas

• The proposed screen combines RSI below 65, stronger best-bid than best-ask volume, and a recent limit-up event.
• The article presents the rules as a way to identify stocks with potentially favorable short-term conditions.
• The prose and code examples differ on the required count of recent limit-up events.
• The article reports no backtest evidence and warns that the screen omits company fundamentals.
• It suggests adding other filters and risk controls, but does not specify or evaluate them.
