What this workflow does

This workflow has 15 nodes and runs on a schedule (cron */15 * * * *). Along the way it connects Postgres. It also calls api.coingecko.com, alphavantage.co and api.twilio.com over HTTP.

How it runs

Trigger: On a schedule (cron */15 * * * *).

1. Fetch cryptocurrency prices from CoinGecko (HTTP Request): calls api.coingecko.com
2. Fetch stock prices from Alpha Vantage (HTTP Request): calls alphavantage.co
3. Combine crypto and stock market data (Merge): merges the data from its input branches
4. Calculate technical indicators (Code): runs custom JavaScript code
5. Call AI model for signal prediction (HTTP Request): calls an HTTP API (POST)
6. Analyze AI signals and confidence (Code): runs custom JavaScript code
7. Validate signal strength and filter (Filter): keeps only the items that match a condition
8. Store trade signal in PostgreSQL (Postgres): uses Postgres
9. Route by signal action (Switch): routes items into 2 branches
10. Generate trading alert message (Code): runs custom JavaScript code

…plus 4 more steps. See the full node list below.
