Bundled dataNone. Data is downloaded on demand from whichever CCXT-supported exchange you configure, via the built-in `freqtrade download-data` command. That covers 100+ exchanges in principle, with Binance, BingX, Bitget, Bybit, Bybit EU, Gate.io, Gate.io EU, HTX, Hyperliquid, Kraken, OKX and OKX EEA (MyOKX) officially tested as of September 2026, plus Bitvavo and Kucoin confirmed by community testing. Bitmart no longer appears in the vendor's exchange documentation. No equities, forex or futures data of any kind; this is a crypto-only tool.No usable current data ships with the library. 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.
