Overview

End-to-end automation from data ingestion to Slack-ready summaries.

The AI agent collects market data hourly for a predefined watchlist and determines Buy, Hold, or Sell signals using RSI and MACD. It fetches daily stock bars, calculates indicators with a Python-based node, and categorizes each ticker. It uses OpenAI to generate a concise, Slack-ready narrative and delivers it to the designated Slack recipient.

No real-time visibility into a watchlist during market hours.
Manual steps to check if the market is open and fetch data.
Inconsistent or ad-hoc indicator calculations.
Delayed or disjointed sharing of insights to Slack.
Fragmented data sources leading to missed signals.
After
Hourly, automated updates during market hours.
Consistent Buy/Hold/Sell labels per ticker.
OpenAI-generated Slack narratives that are consistent.
Slack messages delivered to the correct channel automatically.
Centralized, auditable insight flow for decision making.
Process

How it works

A simple 3-step system that non-tech users can follow.

Step 01

Step 1: Check market status and fetch data

The AI agent uses Alpaca’s clock API to verify market hours and pulls daily bars for the tickers in the watchlist.

Step 02

Step 2: Compute indicators and classify signals

A Python code node calculates RSI and MACD from the retrieved data and assigns Buy/Hold/Sell labels per ticker.

Step 03

Step 3: Summarize and notify

OpenAI generates a concise Slack-ready summary which is posted to the designated Slack user or channel.


Example

Example workflow

One realistic scenario.

At 7:30 AM PT on a Monday, the AI agent retrieves data for 8 tickers, computes RSI and MACD, labels Buy/Hold/Sell, generates a Slack-ready summary, and posts the update to the market-traders channel by 7:45 AM PT.

FAQ

FAQ

Common questions and clear answers.

The AI agent relies on Alpaca for market data, including clock status and daily bars, and uses OpenAI to craft narrative summaries. It maintains an internal watchlist to drive scope. If a data source is unavailable, the agent logs the failure and retries on the next cycle. Updates will indicate any data gaps and retry status.

Yes. You can provide a watchlist of tickers and adjust it as needed. The agent reads the list at startup and periodically refreshes it. If a ticker cannot be fetched, it is skipped with a note in the summary. You can also add or remove tickers to reflect changes in your strategy.

The agent checks market status via Alpaca before each update. If the market is closed, it skips data pulls and summaries for that cycle. It can be configured to send a brief “market closed” notification when appropriate. Otherwise, updates resume when hours reopen.

Updates run hourly during scheduled market hours. The system respects market holidays and skips updates on non-trading days. Each update covers the current tickers, their RSI/MACD, and a short narrative. You can adjust the cadence if needed.

Yes. The Slack destination is configurable per deployment. You specify the user or channel at setup, and the agent posts updates to that target. Permissions and channel restrictions can be enforced. The agent also respects any mention or formatting preferences.

If a data fetch fails, the agent logs the error and attempts a retry on the next cycle. Persistent failures are surfaced in the Slack summary and in an error log for investigation. The retry behavior prevents silent data gaps in updates. You retain visibility into issues and recovery progress.

This agent performs data collection, indicator calculation, and narrative summarization. It does not execute trades. It is a decision-support tool intended to inform human intervention. Always review automated signals and follow your firm’s risk management policies.
