How can I track real-time stock value on a basic plan?

This may sound stupid but im on a basic plan and I want to try and find a way how to evaluate how much stock I have left and its value at any given time in the month.

However, it only allows me to see this at the end of the month with the month-end snapshot.

Is there a simple solution im missing or do I have to purchase an app?

All answers much appreciated.

Thankyou Lance
