# Asset importer

We included a simple set of scripts that showcase how you can automatically import bulk assets into the system.
The example implements a process to download the component assets of the Dow Jones Industrial Average. The components list was taken from [this wikipedia page](https://en.wikipedia.org/wiki/Dow_Jones_Industrial_Average) and put into `apps/asset-import/downloader/tickers.csv`.

## Downloader

The downloader (`apps/asset-import/downloader`) is a simple `python` script that downloads the end-of-day close data of all the financial components mentioned above.

To run it, create a virtual environemnt and install `yfinance` and `pandas` packages, then run the script.
