Live Data and Sources

The market figures on this site are not hand-typed. A small Python job runs on our own server once a day, pulls the numbers straight from Yahoo Finance using the open-source yfinance library, recomputes the returns, and saves them. You can see the exact feed below, including when it last ran, and download the raw file yourself.
