COT - Extreme Zones (Auto + FX/Metals/Crypto Dropdown)

This indicator turns COT positioning into an easy-to-read oscillator that helps you track when market participants may be reaching positioning extremes.

It pulls Commercial Long/Short and Non-Commercial Long/Short from COT reports, computes their net positions, and builds a divergence series (Commercial Net – Non-Commercial Net). That divergence is then normalized into a 0–100 index using a rolling Min/Max window (52/156/260 weeks are common choices).

Why it’s useful

COT extremes can highlight when positioning becomes one-sided. This tool helps you spot those moments quickly via clear, color-coded extreme zones—ideal for timing watchlists, mean-reversion setups, or adding context to trend trades.
