Please see the examples for more code samples and the documentation for more information about the library usage.
To see an example of an application using cryptofeed to aggregate and store cryptocurrency data to a database, please look at Cryptostore. Cryptofeed supports backend callbacks that will write directly to storage or other interfaces. Cryptofeed can be installed from PyPi. It's recommended that you install in a virtual environment of your choosing.
Cryptofeed has optional dependencies, depending on the backends used. You can install them individually, or all at once. To install Cryptofeed along with all its optional dependencies in one bundle:. If you wish to clone the repository and install from source, run this command from the root of the cloned repository. Cryptofeed supports some REST interfaces for retrieving historical data and placing orders.
See the rest package. There are a lot of planned features, new exchanges, etc planned!
If you'd like to discuss ongoing development please join the slack or open a thread in the discussions in GitHub. Cryptofeed wouldn't be possible without the help of many contributors! I owe them and all other contributors my thanks!

Cryptofeed is usually used with few backends one or two and installing the dependencies of all backends is not required. Thus, to minimize the number of dependencies, the backend dependencies are optional, but easy to install. See the file setup. Install all optional dependencies To install Cryptofeed along with all optional dependencies in one bundle:. Arctic backend To install Cryptofeed along with Arctic in one bundle:.
The tool Pipenv allows the installation of the Cryptofeed library and its dependencies without affecting your daily Python environment. Pipenv is based on pip and virtualenv. On an Operating System OS released more than 2 years ago, installing the latest versions of Pip and Pipenv is recommended to fix issues and to enable new features.

However, Python packages installed by the system should not be altered. Thus, we recommend installing Python packages in the user Python environment to limit conflicts with the operating system:. Note: Remember that you are in the sub-shell of the virtual environment. The default Pipfile is configured to install all optional dependencies.
Please, edit the Pipfile to comment the optional dependencies you do not need. See the dependencies listed above the line Optional dependencies. To uninstall a dependency, comment it insert " " in the beginning of the line and run the following command lines:. The [dev-packages] section of the Pipfile lists the Python packages used for the Cryptofeed development.

Pytest is listed in the [dev-packages] section with pytest-asyncio , a Pytest plugin allowing writing unit tests for asyncio functions. The [dev-packages] section of the Pipfile also lists Pylint with many plugins for relevant static code analysis. One more thing: The [dev-packages] section also lists the tool isort.
The following isort options apply the same formatting as black , but only to the import sections:. Feb 16, Dec 26, Nov 13, Sep 29, Aug 26, Aug 1, May 22, Mar 17, Forget Inaccurate Data.
