Interactive Brokers caters to forex traders through its desktop, web, and mobile trading apps. There is an entire section on the Trader Workstation (TWS) desktop dedicated to FX Trading, where you can prepare and place orders for IBKR to execute. Likewise, the web and mobile app enable you to trade forex, and are much easier to use than the TWS desktop version. That being said, many of the advanced features available on TWS for forex trading are not available on the web and mobile apps.
