| Bundled data | Paid license bundles: US Stock Prices (EOD + 1-minute, 2007-present, survivorship-bias-free), IBKR shortable shares, borrow fees and special margin requirements (2018-present, global), Alpaca easy-to-borrow (2019-present).

The default Quandl/WIKI bundle (via NASDAQ Data Link) covers US equities only through March 2018, so you bring your own: either the csvdir bundle, which takes OHLCV CSVs with splits and dividends, or your own custom bundle ingest code. |
