Interactive Brokers Announces the New Industry Standard in Deep Discount Commissions for Professionals

In keeping with our mission of providing low cost trade execution and clearing services to professional traders and investors worldwide, IB is pleased to announce the following new US commissions schedule to take effect Tuesday, November 1, 2005.

Stocks*:	$0.005/Share (all-in)
Options*:	$0.75/Contract (all-in)
Futures:	$0.25 to $1.20/Contract (plus exchange costs)
Forex**:	1 to 2 PIP wide EUR/USD spreads

As you already know, lower commissions does not mean no-frills technology. Over the coming months IB will continue to enhance the industry leading direct access trading platform with the following:

• The addition of new markets and countries to enhance your ability to trade stocks, options, futures, forex, ETFs, and bonds worldwide from a single account
• Additional forex dealers to keep our fx spreads the tightest in the industry
• More real-time risk management tools so you can assess your portfolio risk at any second of the day
• Modifications to our smart router to take advantage of rule changes in the market place so you are assured of always getting best price execution on your trades
• More charting and market scanner functionality

We do not believe that there is another broker providing this much functionality at ANY price in the industry, and we will continue to upgrade our platform to ensure that we remain the trail blazer for professional traders and investors worldwide.

*$1.00 minimum on all orders, no extra ticket charge
**Whereas other brokers inflate their forex spreads with more than their fair share for commissions, IB quotes the best bid/offer from multiple large banks and charges a separate 0.2 PIP commission on EUR/USD.
