lean live deploy

Introduction

Start live trading a project locally using Docker.

$ lean live deploy <project> [options]

Description

Starts local live trading in a Docker container using the quantconnect/lean Docker image. The logs of the algorithm are shown in real-time and the full results are stored in the <project> / live / <timestamp> directory. You can use the --output option to change the output directory.

The given <project> argument must be either a project directory or a file containing the algorithm to backtest. If it is a project directory, the CLI looks for a main.py or Main.cs file, assuming the first file it finds to contain the algorithm to run.

By default, an interactive wizard is shown letting you configure the brokerage and data feed to use. When --environment, --brokerage, or --data-feed is given, the command runs in non-interactive mode and does not prompt for input.

When the --environment option is given, the environment with the given name is used. The given environment must be one of the live environments stored in your Lean configuration file. This means the environment must have the live-mode property set to true.

When --brokerage or --data-feed is given, the live configuration is read from the command-line options. In case a required option has not been provided, the command falls back to the property with the same name in your Lean configuration file. The command aborts if this property also hasn't been set. The required options depend on the selected brokerage or data feed.

The following options are required for each brokerage in non-interactive mode:

If you omit some of the required brokerage or data feed options when running in non-interactive mode, the CLI uses the option values in your LEAN configuration file.

Example non-interactive usage:

$ lean live deploy "My Project" \
    --brokerage "Paper Trading" \
    --data-feed "Interactive Brokers" \
    --ib-user-name "trader777" \
    --ib-account "DU1234567" \
    --ib-password "hunter2" \
    --ib-enable-delayed-streaming-data yes

The Docker image that is used contains the same libraries as the ones available on QuantConnect. If the selected project is a C# project, it is compiled before starting live trading.

By default, the official LEAN engine image is used. You can override this using the --image <value> option. Alternatively, you can set the default engine image for all commands using lean config set engine-image <value>. The image is pulled before starting the local live trading if it doesn't exist locally yet or if you pass the --update flag.
