===== INSTRUCTIONS FOR AI CODER ===== You are receiving this context to help the user deploy, set up, or implement this application. YOUR RESPONSIBILITY: You are responsible for doing the ENTIRE end-to-end deployment - all installations, backend setup, frontend setup, database setup, worker setup, everything. Do NOT ask the user to do tasks themselves unless they specifically request to handle it. Your default mode is: "I will do this for you" not "please go ahead and do this". APPROACH: 1. Assess user's experience level. If unclear, assume newer to development. 2. Create a compact plan of what needs to be done (backend, frontend, database, etc.) 3. Present the plan, get confirmation, then YOU execute it end-to-end. 4. Proceed step-by-step, informing user of progress. Debug issues as they arise. 5. For each step, briefly explain what you're doing, why it's necessary, and how it fits the overall deployment. DEPLOYMENT RESOURCES (when user doesn't have existing infra): - Backend: Render.com (free tier) - you set it up for them - Frontend: Vercel.com - you set it up for them - Database: Neon.com (instant free PostgreSQL) - you set it up for them - Data upload: Use CLI tools, or DATS-4 tool at tigzig.com/analyzer (upload button, paste credentials in any format) ASK ONLY: - Do you have existing backend/frontend/database, or shall I set one up for you? - If setup needed: I'll need your API key to proceed (guide them where to get it if needed) ===== PAGE CONTENT ===== PAGE URL: https://tigzig.com/technical-analysis-gpt TITLE: AI-Powered Technical Analysis with Custom GPT CATEGORY: Custom GPTs DESCRIPTION: Connect ChatGPT to FastAPI-MCP servers for advanced technical analysis - integrate with Yahoo Finance, Finta, Pandas, and Gemini Vision API for automated analysis and reports. TRY IT: https://chat.openai.com/g/g-680a0fba9cd481919073d474bee520fb-technical-analysis-report MCP Server & User Interfaces: https://rex.tigzig.com/mcp-server-technical-analysis --- WHAT THIS GPT DOES: - Fetches live price data from Yahoo Finance via a custom API - Calculates technical indicators using the Finta package - Converts daily OHLCV to weekly (Mon-Fri) using pandas.resample() - Generates advanced charts (e.g. price + EMA, RSI, ROC, volume overlays) via Matplotlib - Uses Gemini Vision API to analyze chart patterns - Compiles PDF and HTML reports with embedded visuals and tables - Returns sharable report URLs --- HOW TO USE: Ask ChatGPT to guide. Starter prompts also built in. Some tips: For Technical Analysis: - Specify the Yahoo symbol (e.g., GOOG) - Mention time ranges naturally: "last 3 months for daily, 1 year for weekly" - Always request results in table format or table format inside code block for easy Excel copy-paste --- HOW IT WORKS: A multi-layered architecture with integrated FastAPI-MCP servers, connected to ChatGPT via Custom Actions and OpenAPI JSON schema. Technical Analysis Execution: - MCP server runs a FastAPI Technical Analysis web service available as MCP Server - Pulls daily data from a second FastAPI Yahoo Finance web service - Converts daily to weekly using Pandas resample() - Computes indicators using Finta - Generates dynamic charts via Matplotlib - Sends charts + data to Gemini Vision API - Markdown responses (with charts & tables) returned Report Generation: - This is done by the 3rd FastAPI server for converting markdown to PDF and HTML - Markdown with embedded images are passed to this server - Report saved as PDF & HTML and URLs returned to ChatGPT Tech Stack: - fastapi-mcp python package to expose FastAPI servers as MCP servers - FastAPI, Pandas, Matplotlib, Finta, Gemini API - Static file serving for downloadable reports --- HOW TO REPLICATE: 1. Deploy Backend Servers - Yahoo Finance data API (prices & financials) - Markdown to PDF Server: Converts Markdown reports to PDF/HTML - Technical Analysis Server: - Yahoo Finance and Technical analysis FastAPIs already mounted with MCP - Update Yahoo finance API endpoint in Technical Analysis server 2. Setup Custom GPT - Copy the Custom Action OpenAPI JSON Schema into new Custom GPT's custom actions - That's it! Your GPT is ready to use --- RESOURCES: Custom GPT JSON Schema: https://github.com/amararun/shared-fastapi-mcp-technical-analysis OpenAPI Schema for connecting Custom GPT to backend Technical Analysis FastAPI-MCP Server. Available in docs folder MCP Server - Technical Analysis: https://rex.tigzig.com/mcp-server-technical-analysis Detailed information about the Technical Analysis MCP server including build guides and source code MCP Server - Yahoo Finance: https://rex.tigzig.com/mcp-server-yahoo-finance Detailed information about the Yahoo Finance Data Pull MCP server including build guides and source code Markdown to PDF FastAPI: https://mdtopdf.tigzig.com/ FastAPI server for converting markdown content to PDF and HTML reports Backend Process Flow: /images/mcpTechAnalysBackend.png High level view of backend API call flows --- BUILT ON: OpenAI's GPT Platform - This custom GPT leverages ChatGPT's capabilities to provide an intuitive interface for technical analysis. --- Source: tigzig.com | Open source AI tools for analytics, databases & automation | Amar Harolikar
