About this skill

Cryptofeed - Real-time cryptocurrency market data feeds from 40+ exchanges. WebSocket streaming, normalized data, order books, trades, tickers. Python library for algorithmic trading and market data analysis.

How to use

  1. Zainstaluj bibliotekę Cryptofeed za pomocą pip install cryptofeed. Jeśli chcesz wszystkie opcjonalne backendy (Redis, MongoDB, Kafka), użyj pip install cryptofeed[all].
  2. Zaimportuj FeedHandler i wybrane giełdy (np. Coinbase, Bitfinex, Kraken) z modułu cryptofeed.exchanges, a także typy kanałów danych (TICKER, TRADES, L2_BOOK) z cryptofeed.defines.
  3. Zdefiniuj funkcje callback, które będą przetwarzać przychodzące dane — na przykład ticker_callback do obsługi notowań lub trade_callback do obsługi transakcji. Każda funkcja otrzyma znormalizowane dane z giełdy.
  4. Utwórz instancję FeedHandler i dodaj do niej źródła danych za pomocą add_feed(), podając giełdę, symbole (np. BTC-USD), kanały, które chcesz obserwować, oraz mapę callbacków.
  5. Uruchom pętlę odbierającą dane za pomocą fh.run() — biblioteka będzie utrzymywać połączenia WebSocket i dostarczać dane w czasie rzeczywistym do zdefiniowanych callbacków.
  6. Opcjonalnie możesz zbudować National Best Bid/Offer (NBBO) łącząc dane z wielu giełd, aby śledzić najlepsze ceny kupna i sprzedaży na rynku.
