Python software for stock market

I am seeking a professional Python Software Developer to build an application for the stock market. I do not have any specific requirements or preferences for the user interface, but I do have specific features that I am looking for. Specifically, I would like the software to have tools for stock analysis, historical data visualization, real-time stock updates, and order execution with system based stop loss and trailing. As far as the project timeline, I am flexible and not in a hurry.
