Stock Market Technical Analysis Alerts
Every weekday at 5 PM, it checks your stocks for Golden or Death Cross signals and alerts Discord if a trend change occurs.
What it does
Get instant Discord alerts when your stocks hit Golden or Death Cross signals every weekday at 5 PM. This workflow monitors your tickers using Alpha Vantage data to spot trend changes before you do.
Step by step
- Configure a cron trigger to run daily at market close for consistent data ingestion.
- Set up an HTTP Request node with the Alpha Vantage API key in the headers or query parameters.
- Create a PostgreSQL table schema with columns for date, ticker, open, high, low, close, and volume.
- Configure the Discord webhook URL in the final HTTP Request node to send messages to the target channel.
Where the LLM does the work
- Generate the JavaScript or Python code within the Code node to correctly calculate the 50-day and 200-day Simple Moving Averages.
- Write the conditional logic that compares current SMA values against previous day values to detect crossover events.
- Draft the JSON payload structure for the Discord webhook to ensure alerts are formatted with clear buy/sell indicators.
Watch out for
PostgreSQL date types can cause timezone mismatches if not explicitly set to UTC during data insertion and retrieval.
The Code node will fail silently on missing historical data for new tickers, so add a check to ensure sufficient rows exist before calculating SMAs.
Discord webhooks require proper JSON formatting or the alert message will be rejected by the API endpoint.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Stock Market Technical Analysis Alerts: Every weekday at 5 PM, it checks your stocks for Golden or Death Cross signals and alerts Discord if a trend change occurs. ## Specification - What it does: Get instant Discord alerts when your stocks hit Golden or Death Cross signals every weekday at 5 PM. This workflow monitors your tickers using Alpha Vantage data to spot trend changes before you do. - Trigger: On a schedule (Scheduled · daily 5 PM weekdays) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Alpha Vantage API: Fetch stock price data - PostgreSQL: Store historical price history - Discord: Send alert notifications ## Known pitfalls, handle each one explicitly in your implementation 1. PostgreSQL date types can cause timezone mismatches if not explicitly set to UTC during data insertion and retrieval. 2. The Code node will fail silently on missing historical data for new tickers, so add a check to ensure sufficient rows exist before calculating SMAs. 3. Discord webhooks require proper JSON formatting or the alert message will be rejected by the API endpoint. ## Reference implementation https://n8n.io/workflows/6692 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Market Data API than Alpha Vantage API?
Yes. Alpha Vantage API is only the example market data api in this recipe. The same flow works with BuiltWith API, CoinGecko API, FRED and GoldAPI. Swap the market data api connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
