Websockets

            # but using the WsClient's functions is more efficient

Note: Authenticated Spot websocket clients can also un/subscribe from/to public feeds.

📍 Futures Client Example Usage

Kraken provides a sandbox environment at https://demo-futures.kraken.com for paper trading. When using this API keys you have to set the sandbox parameter to True when instantiating the respecitve client.

A template Futures trading bot using both websocket and REST clients can be found in /examples/futures_trading_bot_template.py.

Futures REST API

The following example can be found in /examples/futures_examples.py.

from kraken.futures.client import Market, User, Trade, Funding

    print(user.get_open_positions())
    print(user.get_subaccounts())
    # ....

    # ____MARKET_________
    market = Market()
    print(market.get_ohlc(tick_type='trade', symbol='PI_XBTUSD', resolution='5m'))

    priv_market = Market(key=key, secret=secret)
    print(priv_market.get_fee_schedules_vol())
    print(priv_market.get_execution_events())

Futures Websocket Client

The following example can be found in /examples/futures_ws_examples.py.

            # >> apply your trading strategy here <<
            # you can also combine this with the Futures REST clients

    # _____Public_Websocket_Feeds___________________
    bot = Bot()
    # print(bot.get_available_public_subscription_feeds())

    products = ['PI_XBTUSD', 'PF_ETHUSD']
