A-Share Screen Combining Daily Range and Positive MACD in 2021

Summary

This post proposes placing A-shares in a candidate pool when their daily high-low range exceeds 1%, the observation falls in 2021, and MACD is above zero. It interprets the range condition as a sign of greater price movement and positive MACD as a potentially stronger trend. The examples calculate MACD from standard 12-, 26-, and 9-period exponential moving averages and combine the three conditions.

The post offers no performance data or evidence that the filter predicts returns. It notes that the screen ignores other relevant information, including company finances and industry conditions, and suggests checking additional valuation or technical measures and comparing multiple periods. Its rule is a historical screening condition rather than a complete trading strategy: it does not specify entry timing, exits, sizing, transaction costs, or risk controls. The use of a fixed historical year also limits its direct relevance to current stock selection.

Key ideas

• The screen requires a daily high-low range above 1%, a 2021 observation, and MACD above zero.
• The examples use the standard 12-, 26-, and 9-period MACD calculation.
• The post provides no results demonstrating that the conditions generate profitable signals.
• It warns that the filter omits company fundamentals and industry developments.
• The screening rule does not define trade execution, exits, position sizes, or risk limits.
