HighCharts with Angular - Part 2 - Stock Portfolio with Dashboard

In continuation of previous post, now I try to implement the final chapter of the book, https://www.apress.com/gp/book/9781484257432.

The app is live: https://stock-portfolio.zoltanhalasz.net/
Zip repo of client side:

The back-end, which uses an In-Memory database, and Asp.Net Core Web Api, is based on Chapter 7, will use a Yahoo Finance Wrapper, and provide data to the Angular app, as shown in the Web API controller (see book starting with, pages 259).

The Asp.Net Core back-end is live under:

https://stockapi.zoltanhalasz.net/api/getstock

Zip Repo of server side:

I changed the back-end and front-end a little bit, correcting Typos, Formatting (indentation) and changing a little bit the main Stock class of the project.
