A-Share Screen for Rising Lows and Moderate Recent Gains

Summary

This Chinese stock-selection note presents a technical screen combining a daily range condition, a positive but capped ten-day gain, and a rising-bottom pattern. Its indicator formula compares moving averages of lows across several lookback periods and adds conditions based on recent highs, the close’s position within the day’s range, and range relative to a long moving average. A Python example applies related filters to daily A-share data, including checks on candle shape, volume, and low-price moving averages.

The stated rationale is that rising lows can help identify stocks forming a base, while the author acknowledges that the broad screen may admit noise and that this pattern alone may not predict short-term direction. The note recommends combining technical signals with company fundamentals and market or industry context. The code and prose are not fully aligned: some code conditions appear inconsistent with the described thresholds, and the code has potential calculation and data-handling issues. No backtest or results are reported, so the screen’s effectiveness is unestablished.

Key ideas

• The proposed screen combines daily volatility, a bounded positive ten-day return, and a rising-low pattern.
• Its indicator formula uses nested moving averages of lows and additional price-range conditions.
• The Python example adds candle-shape and volume filters, but does not consistently match the prose description.
• The author warns that the screen may produce noise and recommends adding technical and fundamental context.
• The document reports no backtest results or evidence of predictive performance.
