Screening Stocks by Amplitude, Recent Control Signal, and MACD

Summary

This proposed stock screen combines amplitude above a stated threshold, a condition labeled as main-force control on the previous day, and a MACD-related condition referring to two days earlier. The article presents the combination as a way to incorporate short-term price behavior, but it does not define the control measure rigorously. Its formula notes equate that label with the close relative to a five-day average, while the Python example uses the same comparison as a separate filter.

The document includes a basic implementation sketch and suggests adding company fundamentals and adapting MACD parameters to market conditions. It gives no backtest, performance statistics, benchmark, or evidence that the signals identify durable returns. There is also a timing inconsistency: the prose says MACD below zero two days earlier, while the code checks a different index and applies an unclear keep-or-drop condition. The article itself acknowledges that it omits fundamental analysis and that MACD can be sensitive to market changes.

Key ideas

• The screen combines a price-amplitude threshold, a recent price-to-average condition, and a MACD signal.
• The meaning of the stated main-force control condition is not clearly established.
• The prose and code differ on the timing and application of the MACD condition.
• The article provides implementation examples but no backtest or performance evidence.
• It identifies missing fundamental analysis and indicator sensitivity as limitations.
