Supplemental COT Report — Detailed

The Detailed view stacks all 4 Supplemental categories — including the unique Index Traders bucket — in one table. For each you see Longs, Shorts and Net Position, next to the report date and the market's close price. This is the only CFTC format that isolates passive index-fund positioning, and Detailed lets you compare it directly against active hedgers and speculators.

Simplified focuses on a single category (typically Index Traders — the headline Supplemental bucket) with richer per-row metrics. Detailed shows every category on the same row so you can spot when CIT flows decouple from Commercial hedgers.

Supplemental tracks 4 categories (vs Disaggregated's 5), so the table has 14 columns instead of 17. The structure is identical: Long/Short/Net per category, plus the report Date and the market's Close Price.

Index Traders are entities replicating commodity index baskets (S&P GSCI, Bloomberg Commodity Index). They typically buy long-only across multiple agricultural contracts. The Detailed view shows how their flows shift relative to Commercial producers — useful for spotting passive-vs-active divergence.

Yes — Premium subscribers can export every visible column directly from the toolbar. The CSV preserves Long, Short, and Net per category plus Open Interest, with Date as the first column for direct loading into Excel, Google Sheets, or Python.

When you switch the Group Reports filter from Individual to Bi-Weekly, Monthly, Quarterly, Semi-Annual or Annual, the underlying weekly CFTC reports are combined as follows. Snapshot columns (Long, Short, Spreading, Open Interest) are averaged across the period — a monthly row shows the average position across the 4-5 weeks that fall inside that month. Flow columns (Change Long, Change Short, Change OI) are summed, because they represent weekly deltas and the period total is the cumulative flow. NET % CHANGE uses an endpoint formula: it compares the net position in the last week of the period to the net position in the first week, expressed as a percentage. The small ×N chip on the DATE cell shows exactly how many weekly reports were aggregated into that row.
