Screening Chinese Stocks with Range, Volume Ratio, and Weekly MA Crossovers

Summary

This Chinese A-share screening idea combines four conditions: daily price range of at least 1%, volume relative to its five-day average between 1.5 and 6, a weekly five-period moving average crossing above the ten-period average, and an opening price below the prior close. The text presents the range as a way to find active price movement and the volume band as a filter for trading activity that is elevated but not extreme. The moving-average crossover is intended to identify a possible upward turn.

The post gives example screening logic and a Python-style implementation, but reports no backtest or return evidence. It warns that moving-average signals can lag and produce false indications, and that both market-wide and individual-stock risks remain. Suggested refinements include combining technical and fundamental inputs, dynamically filtering selections, using exit rules, and managing position size and diversification. The code and written description provide the proposed rules, not proof of profitability.

Key ideas

• The screen requires a daily range of at least 1% and relative volume from 1.5 to 6.
• It looks for a weekly five-period moving average crossing above the ten-period average.
• The final rule also requires the opening price to be below the previous close.
• The author notes that crossover signals can lag and recommends risk controls and broader screening inputs.
