Stock Screening with Intraday MACD Histogram Contraction

Summary

The proposed stock screen combines three conditions: price amplitude above one, a shortening negative MACD histogram on a 15-minute interval, and a MACD value below zero two days earlier. The accompanying rationale is that larger movement may identify active stocks, while a contracting negative histogram and a prior negative MACD reading may indicate a possible change in direction. The article suggests that a bottom could have formed, but provides no evidence to establish that interpretation.

It warns that indicator-based selection is uncertain, may overlook company fundamentals, and does not ensure short-term returns. It recommends considering other indicators and fundamental analysis, then planning entries and exits rather than following the screen blindly. Formula and Python examples are included, but there is no backtest, benchmark, transaction-cost analysis, or precise validation of the conditions. The material is therefore a screening hypothesis, not a demonstrated strategy; the stated reversal rationale should be tested before use.

Key ideas

• The screen combines price amplitude, a contracting negative 15-minute MACD histogram, and a prior negative MACD reading.
• The proposed interpretation is that these conditions may identify volatile stocks approaching a change in direction.
• The article cautions that technical indicators are uncertain and can omit fundamental information.
• It suggests combining indicator screening with other technical measures and fundamental assessment.
• No backtest or performance evidence is provided to validate the screening hypothesis.
