A Chinese Stock Screen for High Amplitude, Volume, Gaps, and Trend

Summary

The document describes a Chinese equity screening rule that combines daily amplitude above 1, current volume above 10,000 lots, an opening price above the prior close, and an upward-sloping 30-day moving average. It presents the conditions as a way to find active stocks with substantial trading and a positive trend. It also includes example implementations for a screening platform and a Python data workflow, though the Python conditions do not precisely mirror every stated rule.

The author warns that technical filters alone omit company fundamentals and other risks, and suggests adding indicators such as MACD or KDJ alongside valuation, profitability, business, industry, and macroeconomic measures. No backtest results or performance evidence are reported. The rule is therefore an illustrative screening recipe, not evidence of predictive edge; its thresholds, data definitions, timing, and implementation would need independent validation before use.

Key ideas

• The screen combines amplitude, trading volume, a positive opening gap, and a rising 30-day average.
• The post presents both platform-specific conditions and a Python example, but their implementations are not fully aligned.
• The author cautions that technical conditions do not assess company fundamentals or broader risks.
• No performance test is reported, so the screen’s effectiveness is unestablished.
