Chinese Stock Screening with Volatility, Volume, Gaps, and Recent Limit-Ups

Summary

This Chinese market screening idea selects stocks with an amplitude above 1, current trading volume above 10,000 lots, a higher open, and more than two limit-up sessions during the prior ten days. The post frames these conditions as signs of price activity, liquidity, upward momentum, and market attention. It also includes a Python example intended to implement the screen, though the code’s specific calculations do not consistently match every stated condition.

The author cautions that the screen omits company fundamentals and capital flows, and may encourage speculative herding or react to market noise. Suggested improvements include adding financial and industry information and paying attention to data and parameter choices. No backtest results or performance evidence are provided, so the proposed selection logic should be treated as an unvalidated screen rather than a demonstrated strategy.

Key ideas

• The screen combines price amplitude, current volume, a higher open, and multiple recent limit-up sessions.
• The post interprets these conditions as indicators of volatility, liquidity, upward momentum, and market attention.
• The example implementation may not faithfully capture all the stated screening conditions.
• Fundamental data, industry context, and capital flows are identified as missing inputs.
• The document provides no performance test to establish whether the screen is profitable.
