Chinese Stock Screen Using Amplitude, RSI, Turnover, and Relative Strength

Summary

This Chinese-language article outlines an equity screening rule using daily amplitude above 1%, RSI below 65, and a prior-day volume ratio between 3% and 28%. It describes the screen as combining price movement, an RSI ceiling, and recent trading activity. Its illustrative calculation defines amplitude from the day’s high and low relative to the previous close, and computes a volume ratio from current volume divided by prior volume. A sample workflow then ranks selected stocks by relative price strength and retains the strongest fifth of the candidates.

The article warns that turnover or volume activity alone does not show market approval and may lag current liquidity; unusually high activity can coincide with overbought or oversold conditions. It suggests adjusting the range and considering trading value, fund flows, chart patterns, and fundamentals. The article offers no backtest, return figures, or detailed execution and risk rules. Its prose calls the measure actual turnover, while the formula shown is a ratio of consecutive volume observations, so the intended data definition should be checked before implementation.

Key ideas

• The screen combines amplitude above 1%, RSI below 65, and a prior-day volume ratio within a stated band.
• The sample workflow ranks candidates by relative price strength and keeps the strongest fifth.
• The displayed volume-ratio formula compares current volume with the previous period’s volume.
• The article cautions that trading activity can lag liquidity and does not alone indicate market approval.
• No backtest or performance evidence is provided, and the turnover terminology should be verified against the formula.
