I built an n8n workflow that analyzes investments automatically. The workflow: Google Sheets → Market Data → JavaScript → AI → Google Sheets It works by: 1. 📊 Reading the stock/ETF ticker from Google Sheets. 2. 📈 Getting historical market prices. 3. 💻 Using JavaScript to calculate indicators like SMA20, SMA50, and RSI. 4. 🤖 Sending the results to an AI model to explain what the numbers mean in simple language. 5. 📝 Writing the AI analysis back into Google Sheets. Right now, I run it manually with Execute Workflow. My next step is to add a schedule trigger so the workflow can run automatically. I’m learning how to combine APIs, JavaScript, AI, and automation to build practical tools—not just learning AI theory. 🚀
