COT Index
COT Index — Managed Money / Large Spec / Commercials
Short tagline:
Three-line COT Index (0–100) for futures: Large Spec, Managed Money, Commercials. Min-max normalized over a configurable rolling weekly window.
---
Description:
The COT Index plots three trader-group positioning gauges on a single 0–100 scale, derived directly from the CFTC's weekly Commitments of Traders reports. Useful for spotting positioning extremes, divergences between speculator and
commercial flow, and contrarian setups.
# What it shows
Three colored lines:
- 🔵 **Large Speculator** — Managed Money + Other Reportable (combined non-commercial positioning)
- 🟣 **Managed Money** — Managed Money only (Disaggregated) or Leveraged Funds (Financial / TFF)
- 🟠 **Commercials** — Producer/Merchant (Disaggregated) or Dealer/Intermediary (Financial)
Plus reference levels:
- Dashed red at **90** — extreme long
- Dashed green at **10** — extreme short
- Dotted gray at **50** — mid
# Formula
For each group, the indicator computes net positioning (Long − Short), then min-max normalizes over a rolling N-week window:
COT Index = (currentNet − min(net, N)) / (max(net, N) − min(net, N)) × 100
Default N = 156 weeks (3 years). Other common values: 13 (3M), 26 (6M), 52 (1Y).
# Auto contract resolution
Apply to any of the supported futures contracts and the indicator auto-resolves the CFTC code from the chart symbol. No manual configuration needed.

Apply to a non-mapped symbol (e.g. a stock) and the indicator returns a clear runtime error.
# Inputs
- **Lookback (weeks)** — rolling window (4–520, default 156)
- **Show Large Speculator / Managed Money / Commercials** — toggle each line independently
- **Extreme long / short thresholds** — adjust the dashed reference lines
# How to read it
- **Large Spec / Managed Money near 90+** → speculators are very long, often a contrarian sell signal
- **Large Spec / Managed Money near 10−** → speculators are very short, often a contrarian buy signal
- **Commercials are the inverse** of speculators by definition (they take the other side of the trade) — Commercials at 1 typically pairs with Specs near 100
- **Watch divergences** between price and the indicator — speculative positioning peaking while price still rises is a classic distribution warning
# Notes
- Uses TradingView's official `LibraryCOT` (by TradingView) for ticker construction.
- Forces weekly resolution regardless of chart timeframe — values only update on Tuesday COT release days.
- `lookahead = barmerge.lookahead_off` — no future data leak; backtesting is honest.
- Auto-detect requires applying to the **futures** symbol (e.g. `6E1!`), not the spot pair (`EURUSD`). Spot FX charts are not supported.
- Data comes from the Disaggregated report for metals/energy and the Traders in Financial Futures (TFF) report for FX. Both are futures-only (`includeOptions=false`).
