Cost structure for passive investors
Interactive Brokers is a low cost operator in the brokerage industry. The firm is highly profitable despite its low commission structure due to its highly automated trading platform, active client base and low touch service.
Passive investors can take advantage of low trading cost and breadth of product offerings from IB, provided two caveats relevant for certain investors: 1.For accounts with equity below $100,000, IB charges a $10/month minimum activity fee. This fee is reduced by the amount of commission generated for the month. 2.IB charges a fee for real time market data subscriptions. This fee is passed-through from exchanges that actually sell the data product. Passive investors are not advised to subscribe to real time market data as it is unnecessary for the investment style.
