What if you need to access both the outer `this` and the inner `this`. I.e. you still want to get the context changed within the callback, but you also need to access the outer context.
The prices should update as they change in the real markets - it uses Yahoo Finance API for this. It's also already open source: https://github.com/mashlol/trade
Sure. The front-end is just plain old html/js/css. The back-end is Node.js, there's only two endpoints, one is searching for stocks, the other is for serving the index file. I also use the yahoo finance API to get stock prices.
