For a stock information system like that, a client$-$server architecture with a robust back$-$end server would be key. The server could handle the heavy lifting: storing data, running simulations, and processing complex algorithms. The client side would be more about presenting that data in a user$-$friendly way, allowing dealers to customize their views and inputs for the simulations. This setup would let you balance the load, with the server ensuring reliability and speed for the data$-$heavy tasks, and the client ensuring a smooth and personalized user experience. How does that direction sound to you?
