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.

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 initin. - Run
lean cloud pullto pull remotely changed files. - Start programming locally and run backtests in the cloud with
lean cloud backtest "Project Name" --open --pushwhenever there is something to backtest. The--openflag means that the backtest results will be opened in the browser when done, while the--pushflag 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"andlean 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 pushto 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 initin. - 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.
You can save some typing by shortening command names to any unambiguous prefix. For example, lean clo back runs lean cloud backtest. If a prefix could match more than one command, the CLI shows you the options instead of guessing. They're handy for quick typing, but write out full command names in your scripts. A new command could later share the same prefix and break a shortcut that used to work.
CLI Configurations
The following CLI configurations are available. Use the lean config list command to list them at any time.
| Key | Description |
|---|---|
user-id | The user id used when making authenticated requests to the QuantConnect API. |
api-token | The API token used when making authenticated requests to the QuantConnect API. |

By default an interactive wizard is shown letting you configure the brokerage and live data provider to use. If
--environment, --brokerage or --data-provider-live are given the command runs in non-interactive mode. In this mode
the CLI does not prompt for input.
If --environment is given it must be the name of a live environment in the Lean configuration.
If --brokerage and --data-provider-live are given, the options specific to the given brokerage/live data provider must
also be given. The Lean config is used as fallback when a brokerage/live data provider-specific option hasn't been
passed in. If a required option is not given and cannot be found in the Lean config the command aborts.
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 <image>`.

By default an interactive wizard is shown letting you configure the optimizer. If --optimizer-config or --strategy is
given the command runs in non-interactive mode. In this mode the CLI does not prompt for input.
The --optimizer-config option can be used to specify the configuration to run the optimizer with.
When using the option it should point to a file like this (the algorithm-* properties should be omitted):
https://github.com/QuantConnect/Lean/blob/master/Optimizer.Launcher/config.json
If --strategy is given the optimizer configuration is read from the given options. In this case --strategy, --target,
--target-direction and --parameter become required.
In non-interactive mode the --parameter option can be provided multiple times to configure multiple parameters:
- --parameter <name> <min value> <max value> <step size>
- --parameter my-first-parameter 1 10 0.5 --parameter my-second-parameter 20 30 5
In non-interactive mode the --constraint option can be provided multiple times to configure multiple constraints:
- --constraint "<statistic> <operator> <value>"
- --constraint "Sharpe Ratio >= 0.5" --constraint "Drawdown < 0.25"
If --estimate is given, the optimization will not be executed.
The runtime estimate for the optimization will be calculated and outputted.
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 <image>`.
Options:
--output DIRECTORY Directory to store results in (defaults to PROJECT/optimizations/TIMESTAMP)

Development
To work on the Lean CLI, clone the repository, enter an environment containing Python 3.7+ and run pip install -r requirements.txt. This command will install the required dependencies and installs the CLI in editable mode. This means you'll be able to edit the code and immediately see the results the next time you run lean.
If you need to add dependencies, first update setup.py (if it is a production dependency) or requirements.txt (if it is a development dependency) and then re-run pip install -r requirements.txt.
The automated tests can be ran by running pytest. The filesystem and HTTP requests are mocked when running tests to make sure they run in an isolated environment.
Can build the lean CLI by running python setup.py sdist bdist_wheel from the root of the project and to install it pip install --force-reinstall dist/lean-dev-py3-none-any.whl. To update the commands reference part of the readme run python scripts/readme.py from the root of the project, after installing the new version.
Maintainers can publish new releases by pushing a Git tag containing the new version to GitHub. This will trigger a GitHub Actions workflow which releases the current master branch to PyPI with the value of the tag as version. Make sure the version is not prefixed with "v".
