Basically I want to work in a pretend investment bank for a day.
Any ideas?

Here's how it works:
Before you can trade options, you have to apply for options trading.
Most applications are reviewed and approved within 5 business days.
After being approved, decide whether you want to write a covered call, or trade calls or puts.
Options Strategies
* Covered Calls
Sell a covered call to generate income on a stock position you already own. This strategy is designed for conservative investors who are neutral to moderately bullish on a stock currently owned and are willing to sell the stock at a pre-determined price in exchange for receiving a premium for selling the call option.
* Trading Calls & Puts
Buy calls and puts to speculate on the price of a stock. Investors can buy long call options when they feel the price of the underlying stock will increase, or buy long put options when they feel the price will decrease.
