Betfair

NautilusTrader offers adapters for integrating with the Betfair REST API and Exchange Streaming API.

Overview

The following adapter classes are available:

• BetfairInstrumentProvider which enables querying the Betfair market catalogue for betting markets, which are then converted into Nautilus "instruments".
• BetfairDataClient which connects to the Exchange Stream API and streams market data.
• BetfairExecutionClient which enables the retrieval of account information and execution and updates for orders (or bets).

Configuration

The most common use case is to configure a live TradingNode to include Betfair data and execution clients. To achieve this, add a BETFAIR section to your client configuration(s):

from nautilus_trader.config import TradingNodeConfig

config = TradingNodeConfig(
    ...,  # Omitted 
    data_clients={
        "BETFAIR": {
            "username": "YOUR_BETFAIR_USERNAME",
            "password": "YOUR_BETFAIR_PASSWORD",
            "app_key": "YOUR_BETFAIR_APP_KEY",
            "cert_dir": "YOUR_BETFAIR_CERT_DIR",
        },
    },
    exec_clients={
        "BETFAIR": {
            "username": "YOUR_BETFAIR_USERNAME",
            "password": "YOUR_BETFAIR_PASSWORD",
            "app_key": "YOUR_BETFAIR_APP_KEY",
            "cert_dir": "YOUR_BETFAIR_CERT_DIR",
            "base_currency": "AUD",
        },
    }
)

Then, create a TradingNode and add the client factories:

from nautilus_trader.adapters.betfair.factories import BetfairLiveDataClientFactory
from nautilus_trader.adapters.betfair.factories import BetfairLiveExecClientFactory
from nautilus_trader.live.node import TradingNode

# Instantiate the live trading node with a configuration
node = TradingNode(config=config)

# Register the client factories with the node
node.add_data_client_factory("BETFAIR", BetfairLiveDataClientFactory)
node.add_exec_client_factory("BETFAIR", BetfairLiveExecClientFactory)

# Finally build the node
node.build()

API credentials

There are two options for supplying your credentials to the Betfair clients. Either pass the corresponding api_key and api_secret values to the config dictionaries, or set the following environment variables:

• BETFAIR_API_KEY
• BETFAIR_API_SECRET
• BETFAIR_APP_KEY
• BETFAIR_CERT_DIR

When starting the trading node, you'll receive immediate confirmation of whether your credentials are valid and have trading permissions.
