COT Z-Score Analysis helps traders interpret the Commitment of Traders (COT) report using clean, standardized Z-Score metrics. Instead of reading raw positioning tables, the app transforms weekly COT values into easy-to-compare statistical signals that highlight extremes, sentiment shifts, and potential trend changes. Analyze futures markets across all major trader categories—including Producers, Managed Money, Other Reportables, and Open Interest—using consistent lookback periods (4, 12, 24, 36, and 48 weeks). View historical Z-Score trends, detailed tables, and color-coded sentiment ranges that reveal bullish or bearish positioning at a glance. Designed for clarity and speed, the app provides a structured view of institutional futures market behavior.
