I'm not a professional stock picker, but I found the interface confusing. After I made an account and logged in I was not sure what I should be doing or where I should go.

I managed to click around and find google, but then accidentally clicked a trade button and now I have an open trade for 3 shares of google at 100.17! I have no idea how that happened or what it means.

Your site is also a bit slow, but I'm assuming that is because you are under provisioned and this is an alpha.

Good luck.
