This Elixir library provides a wrapper around the Python yfinance so that you can fetch stock price data from Yahoo! Finance®.

Setup

In order to run the underlying Python yfinance library, this library makes use of Pythonx so that you can run Python code inside your Elixir application. By default Yfinance will attempt to start the Python runtime as part of application init, but if you attempt to start two instances of Python Yfinance will assume that you have started it via configuration.

If you do start Pythonx via your application configuration, simply make sure you add the dependencies that this wrapper needs. Below is the default un_init that this library uses for refernce:

[project]
name = "yfinance_ex"
version = "0.6.0"
requires-python = "==3.14.*"
dependencies = [
  "yfinance>=1.2.0",
  "polars>=1.39.0",
  "pyarrow>=23.0.0"
]
