Pretty fun, but not very realistic in the sense that the trade is taken exactly after 10 or 20 days. You don't allow setting stop losses, etc.

Chartarcade.com is a really good stock simulator. It's been around for a while, also uses real stock data, and allows you to buy and sell while incrementing on a per-day or per-week basis. It's actually a really good tool for learning how to buy and sell stocks on a swing basis.

Thanks for the link - that's a very polished tool. My advanced mode lets you step through day-by-day in a similar manner.
