## 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

- 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

- 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
