Looking for a stock market simulation that's as close to the real thing as possible 
Many online brokers have a "virtual" or "paper" trading feature to them.  You can make trades in near-real time with a fake account balance and it will treat it as though you were making the trade at that time.  No need to manage the math yourself - plus, you can even do more complicated trades (One-Cancels-Other/One-Triggers-Other).
