Intraday Stock Screening with MACD Histogram Contraction and Institutional Flow
Summary
This screening concept combines three conditions: amplitude above a stated threshold, a contracting negative MACD histogram on a 15-minute interval, and a positive institutional-flow measure. The proposed interpretation is that elevated movement identifies active stocks, a shrinking negative histogram may signal weakening downside momentum, and positive institutional flow may indicate buying pressure. The document includes example indicator expressions and a rough data workflow for joining price and flow information before filtering candidates.
No performance results, validation period, or comparison with a benchmark are provided, so the claimed potential to improve selection success is unsupported in the text. The examples also leave important operational details unclear, including how amplitude is measured, how the 15-minute MACD condition is aligned with the data, and whether the institutional-flow proxy is consistently available. The source recognizes that technical and flow signals omit company fundamentals and suggests adding fundamental and other technical measures. The rules are therefore best read as a candidate screen rather than a tested trading system.
Key ideas
- The screen requires elevated amplitude, a shortening negative MACD histogram, and positive institutional flow.
- A contracting negative histogram is treated as a possible sign of weakening downside momentum.
- The document supplies illustrative indicator logic but reports no backtest or predictive evidence.
- Data definitions and timing alignment need clarification before the rules can be reproduced reliably.
