Track Singapore COE prices with AI forecasting & smart buy recommendations via Telegram

Introduction Automates Singapore COE price tracking with AI forecasts and buy/wait recommendations. Weekly scraping collects LTA data, enriches with economic indicators, predicts 6-month trends, and alerts users via Telegram/email—helping car buyers and fleet managers make data-driven purchase decisions while avoiding manual tracking.

How it Works Weekly trigger scrapes LTA COE → validates → stores in Google Sheets → calculates indicators → AI forecasts trends → multi-scenario analysis → generates buy/wait signals → sends actionable alerts.

Setup Steps 1. Add OpenAI/NVIDIA API credentials in n8n 2. Authenticate Google Sheets and create spreadsheet 3. Configure Telegram bot or Gmail SMTP 4. Set weekly trigger (Thursday 9AM SGT post-bidding) 5. Adjust alert thresholds in conditional nodes
