Funny enough, the automation&#x2F;optimization&#x2F;scripting&#x2F;algorithm aspects of DFS are a big part of what makes it interesting to me. I have domain knowledge about sports, so DFS is a better testbed for me to learn and explore these areas than, say, automated stock trading.<p>It&#x27;s a great place to practice linear algebra, machine learning, forecasting and projection models, web scrapping, data cleaning&#x2F;normalization, and API wrangling. And all without needing a brokerage account, minimum account balance, or transaction fees!
