Build me a full stack stock trading app inspired by Zerodha.

I want it to feel like a clean modern trading platform where a user can sign up, log in, view a dashboard, check their portfolio, see stock prices, add stocks to a watchlist, and place buy and sell orders. Make the experience simple and polished, with a finance app look and clear navigation.

Use the MERN stack and set it up so the frontend and backend work together smoothly. I’d like the main screens and basic user flows in place, plus sample data if real market data is not available yet. Make sure the app is responsive and usable on desktop and mobile.

If you need to look up current docs online for any setup details, go ahead.
