Analyze stock charts with GPT-4 Vision and send results via Telegram

n8n Workflow: AI-Powered Stock Chart Analysis Bot for Telegram

This is a powerful n8n automation workflow that integrates a Telegram bot with OpenAI's multimodal large language model (GPT-4 Vision) to provide users with real-time stock chart analysis.

Workflow Breakdown

Receive Image: The workflow is initiated by a Telegram Trigger. It activates whenever a user sends an image (e.g., a stock's candlestick chart) to a designated Telegram chat, automatically downloading the file. Image Pre-processing: To optimize the AI's performance and efficiency, the Edit Image node resizes the incoming image to a standard 512x512 pixel format. AI Vision Analysis: The processed image is then passed to a LangChain Chain, which utilizes the OpenAI GPT-4 Vision model. A sophisticated system prompt instructs the AI to act as a professional stock analyst. Intelligent Interpretation: The AI analyzes the image to identify the stock's name, price trend (uptrend, downtrend, or sideways), key support/resistance levels, and volume changes. It then generates a comprehensive analysis report combining technical indicators and market sentiment. Structured Output: To ensure reliability and consistency, the AI's output is parsed into a specific JSON format. This structure includes a searchword (for the industry/sector) and the main content (the analysis text). Send Response: Finally, the workflow extracts the content field from the JSON output and uses the Telegram node to send this professional analysis back to the user as a text message in the same chat.

Key Features
