Hi, I've created an application at http://www.inspectd.com that shows a random 6-month historical chart, and asks you to make a buy/sell decision. It then immediately shows you the actual results over the next 30 days and tracks your "profit" (you start with $100,000 paper money). I think it's pretty damn cool myself because I haven't seen anything like it. I'm an experienced programmer and intermediate trader, and I'd love to get your opinions on my site. Eventually I want to offer web-based historical back-testing of custom-programmable strategies and day-by-day tutoring (it will show you a historical chart, and then walk forward day-by-day asking you to if you want to close your position.) I think it's *very* useful for learning. Please let me know if you think this is a valid idea, and if it's helpful to you as a trader. Your comments are much appreciated!
