Yahoo Finance automation for stock changes

Hi all,

I am trying to add automations to notify me on certain stock changes based on the yahoo finance sensor.

I have two questions related to this:

  1. How can I display certain attributes of such a sensor at the GUI. sensor.amzn will only show me the current stock value. I would also like to display changes

  2. How can I access certain attributes in an automation? E.g. for having a notification after change is larger than 1 percent.
