OPEN-SOURCE SCRIPT
Updated COT Comm Osci

Description
The COT Comm Osci is a sentiment oscillator based on net positions from the weekly Commitments of Traders (COT) report.
It transforms net positions of Commercials, Noncommercials, or Nonreportables into a 0–100 index.
You can define three historical intervals (e.g. 26/ 52 / 156 weeks).
Tip
To improve your analysis, it's recommended to add a separate COT indicator that visualizes raw Long/Short or net positions directly. This helps interpret the oscillator in context.
This script is based on “Commercial Index–Buschi” by MagicEins and has been extended with new features and error handling.
