The core components of the library include:

• instruments
• positions
• portfolios
• orders
• pricing

This library is currently very green and is expected to have significant changes.

Development

This project now uses the uv package manager for dependency management and running tasks.

• uv homepage and install instructions: https://docs.astral.sh/uv/

Once you have checked out the project, you can set up a local virtual environment and install dependencies as follows:

1. Create or reuse a virtual environment with Python 3.11 (recommended):

uv venv -p 3.11

2. Activate the virtual environment (example for bash/zsh):

source .venv/bin/activate

3. Install the project and all development dependencies (tests, docs, etc.):

uv sync --all-extras --all-groups

Notes:

• uv sync reads pyproject.toml and uv.lock and installs the project in editable mode along with dependencies.
• If you only want runtime dependencies, omit --all-groups.
• If you don't need optional extras, omit --all-extras.

To see where the Python interpreter lives for IDE configuration (e.g., PyCharm), after activating the venv you can run:

which python

PyCharm can be pointed at the .venv interpreter in the project root.
