Price on top, and what the big traders were holding underneath it.
COT Index
0–100 · vs last 3 yearsHow extreme today's positioning is compared with this group's own history.
Each group's current net position, rescaled 0–100 against its own high and low over the selected lookback. 0 = most bearish it has been in that window, 100 = most bullish. Unitless by design, so markets of very different sizes can be compared.
Near the most bullish this group has been in the window.
Near the most bearish this group has been in the window.
Near the most bullish this group has been in the window.
Near the most bearish this group has been in the window.
Leaning long, but not yet at an extreme.
COT Index = ((Current − Min) / (Max − Min)) × 100, over the last 3 years
Method credit: the 0–100 normalization goes back to Larry Williams' COT work in the 1980s and was developed and popularized by Stephen Briese, author of The Commitments of Traders Bible.
Disagreement Index
contracts · index 0–100How far apart two trader groups are right now.
Gap = group A's net position minus group B's, measured in contracts. The Disagreement Index rescales that difference 0–100 against its own last 3 years: 0 = the two groups as close together as they get, 100 = as far apart as they get.
Historically extreme disagreement between the two groups.
Left axis: gap in contracts (positive = Managed money is more net long than Producers / merchants). Right axis: disagreement index, 0–100. Gap tracks Managed money − Producers / merchants.
