AI Stock Chart Analyzer: GPT-4 Vision + Telegram Bot

This n8n workflow transforms Telegram into a powerful stock analysis bot. Users send a stock chart image to a designated chat, triggering the workflow to download and resize it to 512x512 pixels for optimal AI processing. GPT-4 Vision, via a LangChain Chain with a custom prompt, acts as a pro analyst to detect stock name, trends (up/down/sideways), key levels, volume shifts, and generates a detailed report blending technicals and sentiment.

The AI output is parsed into structured JSON with 'search_word' for sector and 'content' for analysis text, ensuring consistency. The workflow then sends the polished report back via Telegram, all in seconds. Benefits include effortless, real-time insights without manual charting tools, saving traders hours of analysis.

Ideal for day traders, investors, or finance pros monitoring markets. Use cases: Quick chart reviews during trading sessions, portfolio checks, or sharing analyses in groups. Scalable for high-volume chats, it leverages advanced multimodal AI for accurate, context-aware interpretations beyond basic OCR.
