Deep Dive: Interactive Brokers Platform Review

Interactive Brokers has been the professional trader's broker since 1978. The platform's breadth is unmatched: 150+ global exchanges, forex, futures, bonds, and options all in a single account. The Trader Workstation (TWS) is the most powerful desktop trading platform available to retail traders, with strategy builder, risk navigator, and options analytics tools that rival institutional systems. IBKR's margin rates are consistently 2-3x lower than competitors — on a $500K margin balance, this saves thousands per year. The IBKR Lite tier (commission-free, simplified interface) makes the broker accessible to casual investors who still want the underlying infrastructure quality.
