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:

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.
