Trading Simulator

I am looking for a developer to create a mobile trading simulator that will focus on the stock market. The simulator needs to be advanced and offer a high level of complexity to provide users with a realistic trading experience. The ideal candidate will have experience in developing mobile applications. Additionally, they will have knowledge of financial markets and trading to ensure the simulator accurately reflects real-world trading scenarios. The application should be user-friendly, offer real-time trading data, and the ability to track performance.
