A-Share Screening with Volatility, Recent Gains, and MACD

Summary

This A-share screening idea combines a price-range condition, a recent large daily gain, and a negative MACD reading from two sessions earlier. The article frames the combination as a way to find active stocks that may be entering a trend reversal, and includes example indicator and Python implementations. The code examples do not perfectly match the stated rules: for instance, the indicator code checks a change in DIF rather than simply testing whether the earlier MACD was below zero.

The post offers no backtest results or evidence that the screen predicts returns. It warns that narrow conditions may exclude promising stocks and that volatile shares can move sharply. It suggests adjusting criteria to investment objectives, improving the market data inputs, or combining the screen with other strategies. Treat it as a screening concept that needs precise signal definitions and independent evaluation, rather than a validated trading system.

Key ideas

• The screen combines a price-range threshold, a large daily gain within a recent lookback, and an earlier MACD condition.
• The post describes the selected stocks as active and potentially undergoing a trend change.
• Its example code differs in places from the prose description, so the rules need clarification before implementation.
• The article provides no performance evidence and cautions that narrow filters and volatile stocks carry limitations.
