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
You should use Yahoo data as a seed and then modify it so the user can see results (however fake) faster (or make it a togglable option)
It looks really nice. Can you talk about the technologies you used to build it?
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.
very well done! love the UI! very responsive, has a very good native feel to it. well done!
Why is it only mobile?
I may add a web interface later, this was mostly a project I started to try to make a decent web app for mobile.
