Hi Clark,
your platform looks amazing!
Could you tell a bit about the technical implementation details? Mostly I'd love to know (1) what framework you're using for the modular window-based layout and (2) are you using some sort of library for the rendering of the charts and technical indicators or have you written everything from scratch? And (3) did you work on the project alone and how many hours went into it? Looks like a lot... I study computer science that's why I'm interested

Mark
Thank you for the compliments!
1) I took advantage of the jQuery UI draggable and resizable plugins, but I worked through all of the details like window overlap and data communication.
2) The chart is all mine

It's raw HTML 5 canvas, so I'm pushing every pixel. I compute all the technical indicators.
3) The first prototype of the windowing system was running in June 2011. RTBTC had been a significant side project for over two years at the time of launch.
