Screening Stocks with Positive MACD and a 4–5% Daily Drop

Summary

This proposed stock screen combines a positive MACD reading with a favorable company classification and a daily maximum decline between 4% and 5%. The post describes the approach as blending a technical signal with company-related screening and a short-term price filter. It includes example platform and Python workflows, but the implementation details do not consistently clarify how the company-quality condition is assessed, and some code conditions appear ambiguous or inconsistent with the stated selection logic.

The author argues that positive MACD can indicate an expanding trend and that limiting the daily decline may constrain risk, while also warning that these filters can overlook broader market forces and suppress short-term opportunities. The document provides no backtest, measured results, or evidence that the screen lowers risk. It suggests considering additional information such as trading activity and company financial measures. The selection rules alone do not specify portfolio sizing, trade exits, or how to handle signals across different market regimes.
