Operational Intelligence Summary

IBKR delivers institutional-quality trading tools at retail costs, but requires professional-level commitment to learning and setup. The platform excels in margin rates, international access, and reliability during market stress, while failing completely at user experience and customer support. Success requires treating this as a professional tool investment, not a consumer app upgrade.
