A Chinese Stock Screen for Volatility, Trading Activity, and Positive Opens

Summary

The document describes a Chinese stock selection screen combining a daily price range above 1% of the opening price, a high trading-volume threshold, and a positive opening gap. It frames these filters as a way to find active, liquid stocks where market sentiment may be positive. It also suggests adding indicators such as moving averages or MACD and using stop losses and diversification to manage risk.

The provided examples translate the screen into indicator and Python-style logic, but the implementation does not consistently match the stated criteria: it uses volume where the prose specifies yesterday’s traded value, and it applies a 2% opening-gap threshold although the main description only says the stock opens higher. The article gives no performance results or backtest evidence. Its claim that an active, positive open may precede further gains is a rationale, not a demonstrated predictive relationship; broad market declines and missed candidates are noted risks.

Key ideas

• The screen looks for stocks with a daily range above 1% of the opening price and an upward opening gap.
• The prose adds thresholds for prior-day traded value and current trading volume as activity and liquidity filters.
• The code examples use volume in place of prior-day traded value and set the opening-gap cutoff at 2%.
• The article suggests adding technical indicators and using stop losses and diversification.
• No backtest or performance evidence is provided, and the stated risks include market declines and missed stocks.
