Screening Chinese Stocks by Intraday Range, Volume, and Prior Limit-Ups

Summary

This stock-selection screen combines current trading activity with a history of sharp advances. It looks for shares with an amplitude above 1, current volume above 10,000 lots, a higher open, and at least two limit-up sessions within the prior 500 days. The rationale is that range, volume, and a higher open indicate active trading, while earlier limit-ups may identify stocks that have attracted strong demand. The document also suggests adding fundamental measures such as market value, profitability, and growth when assessing candidates.

The post provides an explanation and sample implementation, but no backtest, performance statistics, or evidence that the filters predict future returns. Its code does not consistently implement every stated condition: for example, it checks maximum historical volume and price fields rather than clearly confirming current volume and a higher open. The author notes that technical signals can overlook company fundamentals and can be distorted by capital flows, sector moves, and market style. Treat the screen as a hypothesis requiring careful validation and risk controls.

Key ideas

• The screen combines amplitude above 1 and current volume above 10,000 lots with a higher open.
• It also requires at least two limit-up sessions within the previous 500 days.
• The rationale is to identify actively traded shares with a record of strong demand.
• The post recommends considering fundamental measures alongside technical filters.
• It provides no performance evidence, and its sample code may not match all stated conditions.
