Chinese Stock Screen for Volatility, Rising Averages, and Buying Pressure

Summary

This proposed screen selects mainland Chinese main-board stocks using three short-term conditions: amplitude above a threshold, a rising and diverging moving-average pattern, and a buy-side volume ratio above 1.3. The article interprets these as signals of price movement, near-term upward direction, and stronger buying activity. It also sketches a Python workflow using historical price data, a five-period moving average, tick-level buy and sell volumes, and listing-date filtering.

The screen is not supported by reported backtest results or performance measurements. The article itself cautions that short-term indicators can be affected by market cycles and rapid trading, and suggests combining them with longer-term trend, valuation, or industry filters. Its written criteria and code references are not fully aligned, so the exact amplitude and volume definitions should be checked before implementation. These conditions are screening ideas, not evidence that selected stocks will outperform.

Key ideas

• The screen combines price amplitude, a short-term moving-average condition, and a buy-to-sell volume ratio above 1.3.
• The intended universe is mainland Chinese main-board stocks.
• The example implementation uses historical prices, a five-period moving average, and tick-level trading volumes.
• The article reports no backtest evidence and warns that short-term signals can be noisy.
• The written rules and code references differ in places, so definitions need verification.
