How I Built A Technical Analyst AI Agent in n8n With No Code

The video demonstrates how to build a no-code AI technical analyst agent using n8n, integrated with Telegram for interaction and leveraging AI models for financial chart analysis.

Key Technological Concepts & Product Features:

• AI Agent Setup:
  • The AI agent listens for messages in Telegram, where users send stock tickers (e.g., Apple).
  • The agent forwards the ticker to a custom n8n workflow/tool called get chart.
• get chart Tool:
  • Takes the stock ticker as input.
  • Makes a POST request to the chart-image.com API to generate a stock chart with technical indicators (candlestick, MACD, volume, support/resistance).
  • Retrieves the chart URL in JSON format (important for proper image handling).
  • Downloads the chart image in binary format.
  • Sends the image to an OpenAI image analysis node (GPT-4V) to generate a brief technical analysis.
  • Returns this analysis to the AI agent.
• AI Model Usage:
  • Uses Anthropic Claude 3.5 for generating more detailed and well-formatted technical analysis based on the initial analysis from the image.
  • The analysis covers candlestick patterns, trends, MACD, volume, support/resistance, and provides key takeaways.
  • Emphasizes that the output is for informational purposes, not financial advice.
• Workflow Details:
  • Telegram messages trigger the workflow.
  • The workflow extracts the ticker, sends API requests, processes responses, and sends back results to Telegram.
  • API integration with chart-image.com involves handling authorization headers, content-type settings, and switching response formats between binary and JSON.
  • Demonstrates how to import curl commands into n8n HTTP request nodes for easier setup.
  • Provides tips for testing workflows by pinning data inputs rather than triggering through Telegram every time.
• User Resources & Community:
  • The complete workflow is available for free download by joining the creator’s free school community.
  • A paid community is offered for more hands-on learning with live calls and classroom resources.
  • AI consulting services are also available through the creator’s website.

Guides/Tutorials Provided:

• How to set up Telegram integration with n8n for AI agent communication.
• How to create and configure the get chart tool using HTTP requests to chart-image.com API.
• How to handle different response formats (JSON vs binary) and headers for API calls.
• How to use OpenAI’s image analysis node to generate technical analysis from stock charts.
• How to chain AI tools (OpenAI and Anthropic) for layered analysis.
• Tips for workflow testing and debugging within n8n.
• How to import curl commands into n8n HTTP nodes for quick API integration.

Main Speakers/Sources:

• The video is presented by a single creator (unnamed in subtitles) who builds and explains the AI agent and workflows step-by-step.
• The AI models used are Anthropic Claude 3.5 and OpenAI GPT-4V.
• The chart generation API is from chart-image.com.
• The platform used for automation is n8n.
• Telegram is used as the messaging interface for user interaction with the AI agent.

This video serves as both a tutorial and a product showcase for building an AI-powered technical stock analyst with no coding required, leveraging modern AI and API integrations within n8n workflows.
