Fantasy trading application

Hello,

I've just developed a fantasy online trading application, and am looking for some users to play around with it and test it out. It's been developed for an MSc project, and I could do with some feedback.

Once registered, £100,000 is deposited into your account. You can then buy and sell shares in companies listed on the LSE. It uses Intra-day data from Yahoo, and valid EOD data for stock charts.

I have developed it with little understanding in trading, so there are bound to be glaring errors in the way that things work. Any feedback would be apreciated.

You can register and play at: www.techamigo.net/fsm

thanks,
Mark.

The site appears to be working ok now - I registered but I don't trade shares - looks like a pretty good effort to me - best of luck Mark
