Devigger - Sports Betting Statistical Arbitrage Tool

A Python application that analyzes betting odds from FanDuel and Pinnacle to find profitable betting opportunities using statistical arbitrage techniques.

To use, run python main.py [bankroll size]

Features

  • Scrapes real-time odds from FanDuel and Pinnacle sportsbooks by reverse-engineering their APIs

    • Because of rate limiting, certain sports have sleep time, so GUI should open in around one minute
