Possible to add a tracking total?

[Bjarndyrakongur]

I am so sorry that I'm asking such a basic coding question, but I know almost nothing about coding and am simply an end user.

This tracker has been an awesome addition to my desktop, but ideally I'd like to display a number that tracks the value of my portfolio. This would mean taking the value of each of the symbols I'm tracking, multiplying them by a set amount (i.e., the amount of that crypto that I own) and then adding the total values into a single number.

As all the moving data is available in the code, and adding the fixed data (i.e., how much I hold) should be a simple field I can populate, I'm sure that this is like junior grade coding (unless you're me, in which case it may as well be quantum physics). Is this something anyone could help with?
