Volatility, Shortening 15-Minute MACD, and Recent Limit-Up Stock Screen

Summary

This short-term stock screen combines three signals: a high-low range greater than one, a shortening negative MACD histogram on a 15-minute chart, and at least one limit-up move during the past month. The document interprets the range as a sign of substantial price movement, the contracting negative histogram as a possible shift in momentum, and a recent limit-up as evidence of market attention. It includes formula and Python examples, but does not present a backtest or measured returns.

The author warns that technical and sentiment signals can overlook business fundamentals, and that recent limit-up stocks may reflect speculation and face reversals. Suggested refinements include reviewing the cause and persistence of each limit-up event, adding other technical indicators, and considering fundamental data. The examples should be treated cautiously: the code’s thresholds and lookback handling are not fully reconciled with the prose, and a signal’s presence at any point in a data window does not by itself establish a current entry opportunity.

Key ideas

• The proposed screen combines a price-range threshold, a contracting negative 15-minute MACD histogram, and a recent limit-up event.
• The document treats the MACD condition as a possible sign of changing momentum.
• No backtest or performance evidence is provided.
• Recent limit-up events may reflect speculation and can be followed by reversals.
• The example logic has unclear alignment between its written conditions, thresholds, and lookback handling.
