Stock Screening with Shortening 15-Minute MACD Bars and Lower Lows

Summary

This stock-selection approach combines three filters: daily price amplitude above 1, a current-day low below the previous day’s low, and shortening MACD histogram bars on a 15-minute chart. The article interprets the amplitude filter as a way to find volatile stocks and the lower low as a sign of an upward move, while shorter negative MACD bars are taken as evidence that selling pressure may be easing. Together, the conditions aim to identify a possible short-term reversal.

The article provides example indicator logic and partial Python code, but no backtest, performance figures, or worked trade examples. Its explanation of a lower current-day low as evidence of an upward trend is questionable, and the sample code does not clearly implement all three conditions or a complete trading strategy. It also omits fundamental and broader market analysis, and acknowledges that technical signals can fail. The setup is best read as a screening idea that would require precise definitions, testing, and risk controls before use.

Key ideas

• The screen combines price amplitude, a lower daily low, and shortening 15-minute MACD bars.
• Shorter negative MACD bars are treated as a possible sign that downward momentum is weakening.
• The article presents no empirical performance evidence for the proposed screen.
• Its code is incomplete, and its interpretation of a lower low as an upward trend is questionable.
