Install the app's required packages:
$ pip install -r requirements.txt
(Recommended) To keep the package installation local/within a virtual environment, run these before the pip command:
$ python -m venv venv
$ source venv/bin/activate
Options data for your preferred ticker can be downloaded here to manually update files in the data directory (which the calc module uses).
For automatic updates, the app's scheduler fetches compatible CSV data from an API. If you have one, provide its URL in a .env file:
API_URL=YOURAPIURLAlternatively, you can disable this function by commenting out these lines in my_app.py:
# sched.add_job(sensor)
# sched.add_job(sensor, CronTrigger.from_crontab("0,30 13-20 * * 0-4", timezone=UTC))
Upon completion, run the Dash app (available at https://localhost:8050):
$ python my_app.py
