Description

How it works:

Reads commodity symbols (GCUSD, SIUSD, CLUSD, NGUSD, etc.) from a Google Sheet
Fetches the live commodities-quote Skill from GitHub and builds an Octagon Agent prompt for each symbol
Calls Octagon Agent for real-time quotes, parses the response, and writes price, change, ranges, volume, and moving averages back to the sheet

Set up steps:

Takes about 5 minutes
Connect Google Sheets, OpenAI, and Octagon credentials
Point the Sheets nodes at your commodities sheet with a Symbol or Ticker column
Detailed configuration notes live in the sticky notes inside the workflow
