Datasets

Licensing

Introduction

You can license datasets in the Dataset Market to use in the cloud for live trading and research or to download locally. We have contracts with the data providers in the Dataset Market that define the costs of each license. All of the datasets can be used in QC Cloud. There are some free licenses, but we can't freely redistribute most of the datasets.

Free

We strive to make as many datasets available for free to use in the cloud and to download locally as possible. We also list proprietary datasets that are available for license using our cloud or download paid licensing. Most price data is free for use in the cloud.

Cloud

If you have a Cloud license for a dataset, you can access the dataset in the Algorithm Lab for research, backtests, and live trading. The cost of the license is added to your monthly bill, which you can pay with your organization's credit card or QuantConnect Credit balance. With one Cloud license for a dataset, all of the members in your organization can access the dataset in the cloud.

Add Cloud Access

You need an organization above the Free tier to purchase cloud access to datasets.

Follow these steps to add cloud access to datasets:

  1. Log in to the Algorithm Lab.
  2. Open the listing page of a dataset for which you want to gain cloud access.
  3. On the dataset listing page, click the Pricing tab.
  4. Under the Cloud Access section, click SUBSCRIBE.
  5. On the Pricing page, click Proceed to Checkout.

Remove Cloud Access

Follow these steps to remove cloud access to datasets:

  1. Open the organization homepage.
  2. Click Edit Plan.
  3. On the pricing page, click the Customize Plan > Build Your Own Pack > Data tab.
  4. In the Datasets Subscriptions section, next to the name of the dataset you want to remove, click Added.
  5. Click Proceed to Checkout.

Download

If you have a Download license, you can store datasets on your local machine. This download is for the licensed organization's internal LEAN use only and cannot be redistributed or converted in any format. If you study the data and produce some charts, you may share images of the charts online if the original data can't be to reconstructed from the image.

The cost of the license depends on the dataset and it's calculated on a per-file or per-day basis. You must pay for the Download license with your organization's QuantConnect Credit and you need the CLI set up to download datasets. Follow these steps to generate commands to download datasets:

  1. Open the listing page of the dataset that you want to download.
  2. Click the CLI tab.
  3. Fill in the Command Line Generator form.
  4. Select Windows or Unix.
  5. The CLI command to download the dataset displays.

To keep your local files up to date, you'll need to download the new files whenever new data becomes available.
