Stock Screening with Daily Amplitude, Weekly MACD, and Position Changes

Summary

This Chinese stock-selection proposal combines three filters: daily amplitude above 1, a positive weekly MACD histogram, and a current-day position increase ratio above 5%. The article interprets amplitude and weekly MACD as signs of technical strength, while the position-change ratio is intended to indicate current market interest. It supplies example indicator logic and partial Python code, but the implementations do not fully align: for example, the code uses the standard deviation of daily highs as its amplitude test and estimates position increase from changes in volume.

The article acknowledges that the screen leaves out other market and company information and may fail when conditions change. It recommends adding technical and fundamental measures, such as volume, valuation ratios, and other indicators, while adapting parameters to the market and time horizon. No backtest or measured return evidence is included, so the proposed rationale is not a demonstration that the filters predict gains.

Key ideas

• The proposed screen requires daily amplitude above 1, a positive weekly MACD reading, and a position-increase ratio above 5%.
• The rationale combines technical momentum with a measure intended to represent current investor interest.
• The sample code uses proxies that may not match the stated indicator definitions.
• The article warns that the screen omits other relevant information and may fail as market conditions change.
• It presents no performance testing for the proposed selection rules.
