Lean CLI

QuantConnect Lean CLI

The Lean CLI is a cross-platform CLI aimed at making it easier to develop with the LEAN engine locally and in the cloud.

Visit the documentation website for comprehensive and up-to-date documentation.

Highlights

Installation

The CLI can be installed and updated by running pip install --upgrade lean.

Note that many commands in the CLI require Docker to run. See Get Docker for instructions on how to install Docker for your operating system.

Note: Some Linux users may need to install tkinter using the following commands:

For Python 3

sudo apt-get install python3-tk

For Python 2.7

sudo apt-get install python-tk

After installing the CLI, open a terminal in an empty directory and run lean init. This command downloads the latest configuration file and sample data from the QuantConnect/Lean repository. We recommend running all Lean CLI commands in the same directory lean init was ran in.

Usage

The Lean CLI supports multiple workflows. The examples below serve as a starting point, you're free to mix local and cloud features in any way you'd like.

A cloud-focused workflow (local development, cloud execution) with the CLI may look like this:

Open a terminal in the directory you ran lean init in.
Run lean cloud pull to pull remotely changed files.
Start programming locally and run backtests in the cloud with lean cloud backtest "Project Name" --open --push whenever there is something to backtest. The --open flag means that the backtest results will be opened in the browser when done, while the --push flag means that local changes are pushed to the cloud before running the backtest.
Whenever you want to create a new project, run lean create-project "Project Name" and lean cloud push --project "Project Name" to create a new project containing some basic code and to push it to the cloud.
When you're finished for the moment, run lean cloud push to push all locally changed files to the cloud.

A locally-focused workflow (local development, local execution) with the CLI may look like this:

Open a terminal in the directory you ran lean init in.
Run lean create-project "Project Name" to create a new project with some basic code to get you started.
Work on your strategy in ./Project Name.
Run lean research "Project Name" to start a Jupyter Lab session to perform research in.
Run lean backtest "Project Name" to run a backtest whenever there's something to test. This runs your strategy in a Docker container containing the same packages as the ones used on QuantConnect.com, but with your own data.

Commands

Note: the readme only contains the --help text of all commands. Visit the documentation website for more comprehensive documentation.

`lean backtest`

Backtest a project locally using Docker.

Usage: lean backtest [OPTIONS] PROJECT

  Backtest a project locally using Docker.

  If PROJECT is a directory, the algorithm in the main.py or Main.cs file inside it will be executed.
  If PROJECT is a file, the algorithm in the specified file will be executed.

  Go to the following url to learn how to debug backtests locally using the Lean CLI:
  https://www.lean.io/docs/v2/lean-cli/backtesting/debugging

  By default the official LEAN engine image is used. You can override this using the --image option. Alternatively you
  can set the default engine image for all commands using `lean config set engine-image <img>`.

Options:
  --output DIRECTORY              Directory to store results in (defaults to PROJECT/backtests/TIMESTAMP)
  -d, --detach                    Run the backtest in a detached Docker container and return immediately

See code: lean/commands/backtest.py

`lean build`

Build Docker images of your own version of LEAN.

Usage: lean build [OPTIONS] [ROOT]

  Build Docker images of your own version of LEAN.

  ROOT must point to a directory containing the LEAN repository:
  https://github.com/QuantConnect/Lean

  When ROOT is not given, the current directory is used as root directory.

  This command performs the following actions:
  1. The lean-cli/foundation:latest image is built from Lean/DockerfileLeanFoundation(ARM).
  2. LEAN is compiled in a Docker container using the lean-cli/foundation:latest image.
  3. The lean-cli/engine:latest image is built from Lean/Dockerfile using lean-cli/foundation:latest as base image.
  4. The lean-cli/research:latest image is built from Lean/DockerfileJupyter using lean-cli/engine:latest as base image.
  5. The default engine image is set to lean-cli/engine:latest.
  6. The default research image is set to lean-cli/research:latest.

  When the foundation Dockerfile is the same as the official foundation Dockerfile, quantconnect/lean:foundation is used
  instead of building a custom foundation image.

Options:
  --tag TEXT  The tag to apply to custom images (defaults to latest)
  --verbose   Enable debug logging
  --help      Show this message and exit.

See code: lean/commands/build.py

`lean cloud backtest`

Backtest a project in the cloud.

Usage: lean cloud backtest [OPTIONS] PROJECT

  Backtest a project in the cloud.

  PROJECT must be the name or id of the project to run a backtest for.

  If the project that has to be backtested has been pulled to the local drive with `lean cloud pull` it is possible to
  use the --push option to push local modifications to the cloud before running the backtest.

Options:
  --name TEXT  The name of the backtest (a random one is generated if not specified)
  --push       Push local modifications to the cloud before running the backtest
  --open       Automatically open the results in the browser when the backtest is finished
  --verbose    Enable debug logging
  --help       Show this message and exit.

See code: lean/commands/cloud/backtest.py

`lean cloud live`

Interact with the QuantConnect cloud live deployments.

Usage: lean cloud live [OPTIONS] COMMAND [ARGS]...

  Interact with the QuantConnect cloud live deployments.

Options:
  --help  Show this message and exit.

Start live trading for a project in the cloud.

Usage: lean cloud live deploy [OPTIONS] PROJECT

  Start live trading for a project in the cloud.

  PROJECT must be the name or the id of the project to start live trading for.

  By default an interactive wizard is shown letting you configure the deployment. If --brokerage is given the command
  runs in non-interactive mode. In this mode the CLI does not prompt for input or confirmation. In non-interactive mode
  the options specific to the given brokerage are required, as well as --node, --auto-restart, --notify-order-events and
  --notify-insights.
