What this workflow does
This AI workflow has 15 nodes and runs on a schedule (cron 0 20 * * 3). Along the way it connects Google Sheets, Telegram and OpenRouter Chat Model. It also calls onemotoring.lta.gov.sg over HTTP.

- Extract COE Price Data (Code): runs custom JavaScript code
- Store in Google Sheets (Google Sheets): append
- Retrieve Historical COE Data (Google Sheets): uses Google Sheets
- Calculate Technical Indicators (Code): runs custom JavaScript code
- Prepare AI Prediction Prompt (Edit Fields (Set)): sets 1 field: predictionPrompt
- AI Agent: runs an AI agent, with model: OpenRouter Chat Model
- Generate Buy Recommendations (Code): runs custom JavaScript code
- Format HTML Report (Code): runs custom JavaScript code
- Check for Buy Opportunities (If): checks a condition and branches into true / false

Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in AI Agent - COE Analysis (v1.7): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) AI Agent - COE Analysis (v1.7) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
