What this workflow does

This AI workflow has 31 nodes and runs on a schedule (cron 0 20 * * 3) (plus 1 other trigger). Along the way it connects Google Sheets, Telegram, OpenRouter Chat Model and Airtable. It also calls onemotoring.lta.gov.sg and eservices.mas.gov.sg over HTTP.

How it runs

Trigger: On a schedule (cron 0 20 * * 3) (plus 1 other trigger).

  1. Scrape COE Data from OneMotoring (HTTP Request): calls onemotoring.lta.gov.sg
  2. Scrape with Retry Logic (Code): runs custom JavaScript code
  3. Retrieve Historical COE Data (Google Sheets): uses Google Sheets
  4. Extract COE Price Data (Code): runs custom JavaScript code
  5. Calculate Technical Indicators (Code): runs custom JavaScript code
  6. Store in Google Sheets (Google Sheets): append
  7. Data Validation Check (If): checks a condition and branches into true / false
  8. Prepare AI Prediction Prompt (Edit Fields (Set)): sets 1 field: predictionPrompt
  9. Merge: merges the data from its input branches
  10. Extract Economic Indicators (HTTP Request): calls eservices.mas.gov.sg

…plus 17 more steps. See the full node list below.

Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
