Scans CFTC futures positioning for crowded longs, crowded shorts, and sharp weekly shifts across financial and physical futures, with historical percentile and z-score context.

1. Scan crowded longs, crowded shorts, and the largest weekly changes.
2. Choose one contract for historical percentile, z-score, and price context.
3. Change cohorts or the crowding lookback only when the research question requires it.

COT is a Tuesday position snapshot normally released Friday; it is not a real-time flow feed.
