Kraken

Kraken cryptocurrency exchange integration adapter.

This subpackage provides an instrument provider, data client, execution client, configurations, and constants for connecting to and interacting with Kraken’s API.

For convenience, the most commonly used symbols are re-exported at the subpackage’s top level, so downstream code can simply import from nautilus_trader.adapters.kraken.

degrade(self) → void

Degrade the component.

While executing on_degrade() any exception will be logged and reraised, then the component will remain in a DEGRADING state.

Warning

Do not override.

If the component is not in a valid state from which to execute this method, then the component state will not change, and an error will be logged.

WARNING: This may lead to unintended liquidation of wallet assets if strategies are not designed to handle spot positions appropriately.

  • spot_positions_quote_currency (str, default "USDT") – The quote currency to use when generating spot position reports. Only instruments with this quote currency will have positions reported.

  • spot_account_type (AccountType, default AccountType.CASH) – The account type for spot trading. Set to AccountType.MARGIN to enable: - TradeBalance-based margin reporting (used margin, free margin, equity). - OpenPositions-based position reconciliation. - Per-order leverage via SubmitOrder.params = {"leverage": N}. Has no effect when product_types includes KrakenProductType.FUTURES.

  • default_leverage (int, optional) – Default leverage multiplier for spot margin orders when not specified per-order. For example, 3 sends "3:1" to Kraken. None means cash (no leverage sent). Per-order override: pass {"leverage": N} in SubmitOrder.params.

  • margin_balance_asset (str, optional) – Summary-display asset for TradeBalance margin metrics (e.g. "ZUSD", "ZGBP", "ZEUR", "USDT"). Controls the denomination of equity, free margin, used margin, and other summary figures returned by Kraken’s TradeBalance endpoint. None lets Kraken default to ZUSD. Display-only: Kraken converts internally; per-position figures from OpenPositions remain in the traded pair’s quote currency. Only effective when spot_account_type=AccountType.MARGIN.

Examples

Spot margin account with 3x default leverage:

from nautilus_trader.model.enums import AccountType
from nautilus_trader.adapters.kraken.config import KrakenExecClientConfig

config = KrakenExecClientConfig(
    api_key="...",
    api_secret="...",
    spot_account_type=AccountType.MARGIN,
    default_leverage=3,
)

Override leverage on a single order:

order = strategy.order_factory.limit(
    instrument_id=BTC_USD,
    order_side=OrderSide.BUY,
    quantity=Quantity.from_str("0.01"),
    price=Price.from_str("50000.00"),
    params={"leverage": 5},  # overrides default_leverage for this order
