Market, economic, and alternative data feeds for quant work. Export CSVs from the free tier and upload them to ground financial analysis notebooks.
Nasdaq Data Link (formerly Quandl) aggregates market, economic, and some alternative data feeds from many providers, with a free tier covering historical prices and macro indicators well enough for most notebooks. A financial analysis notebook can pull a clean CSV here instead of scraping exchange data by hand. Premium datasets sit behind a paywall, so check whether the series you need sits in the free tier first.
