We need virtual stock trading software, there shall be separate mobile apps for Android and iOS platform. Also we need a back-end to create users, once user is created.
Mobile app user can login and create watchlist by adding stocks(scrips). Watchlist shall show real time data via WebSocket API. User can buy/sell stocks virtually and can view order book, trade book, net profit/loss.
Both android and iOS apps should have same look and feel.
Also backend panel should all connected users, updated in real-time. Also panel should have all orders and trades of all users, updated in real-time.
We can use any platform, react native with back-end in Fireback etc, or flutter or Xamarin. Or even if any developer wants to develop two separate mobile apps we are open to it.
Developers having experience in developing real time communications should only bid. It is not inventory management system.
