Interactive Brokers

NautilusTrader offers an adapter for integrating with the Interactive Brokers Gateway via ib_insync .

Note : If you are planning on using the built-in docker TWS Gateway when using the Interactive Brokers adapter, you must manually install docker (due to current build issues). Run a manual pip install docker inside your environment to ensure the Gateway can be run.

Overview

The following integration classes are available:

• InteractiveBrokersInstrumentProvider which allows querying Interactive Brokers for instruments.

• InteractiveBrokersDataClient which connects to the Gateway and streams market data.

• InteractiveBrokersExecutionClient which allows the retrieval of account information and execution of orders.

Instruments

Interactive Brokers allows searching for instruments via the qualifyContracts API, which, if given enough information can usually resolve a filter into an actual contract(s). A node can request instruments to be loaded by passing configuration to the InstrumentProviderConfig when initialising a TradingNodeConfig (note that while filters is a dict, it must be converted to a tuple when passed to InstrumentProviderConfig ),

At a minimum, you must specify the secType (security type) and symbol (equities etc) or pair (FX). See examples queries below for common use cases

Example config:

config_node = TradingNodeConfig(
    data_clients={
        "IB": InteractiveBrokersDataClientConfig(
            instrument_provider=InstrumentProviderConfig(
                load_all=True,
                filters=tuple({"secType": "CASH", "symbol": "EUR", "currecy": "USD"}.items())
            )
        )
)

Configuration

The most common use case is to configure a live TradingNode to include Interactive Brokers data and execution clients. To achieve this, add a IB section to your client configuration(s) and set the name of the environment variables containing your TWS (Traders Workstation) credentials:

config = TradingNodeConfig(
    ...,  # Omitted 
    data_clients={
        "IB": {
            "username": "TWS_USERNAME",
            "password": "TWS_PASSWORD",
        },
    },
    exec_clients={
        "IB": {
            "username": "TWS_USERNAME",
            "password": "TWS_PASSWORD",
        },
    }
)

Then, create a TradingNode and add the client factories:

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

# Register the client factories with the node
node.add_data_client_factory("IB", InteractiveBrokersLiveDataClientFactory)
node.add_exec_client_factory("IB", InteractiveBrokersLiveExecClientFactory)

# Finally build the node
node.build()

API credentials

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

• TWS_USERNAME

• TWS_PASSWORD

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