IBKR's APIs are free for use by clients with fully open and funded IBKR Pro accounts. There are no fees associated with use of our APIs, but in certain circumstances commissions can be assessed differently for API-originated orders compared to orders submitted via IBKR's own platforms. Additionally, FIX integration entails a monthly commission minimum.
Please Note
- Directed API orders cannot use the Tiered fee structure. SmartRouted API orders can use either the Tiered or Fixed structure.
