Interactive Brokers
Global multi-asset brokerage with programmatic access through TWS API, the Client Portal REST API, and the ib_insync ecosystem.
What it is good at
Breadth. Equities, options, futures, FX and bonds across dozens of venues from one account and one API — the practical default for multi-asset systematic work.
Scored against the five published criteria, identically for every entry, by the editors of this site. Scores are never sold and are not affected by any commercial relationship. Read the method.
What to watch
The API surface is old and its conventions show it. Budget real time for connection handling and order state management.
This section is not optional and is not negotiable. Every entry in the register carries one, whatever the commercial relationship.
Access it
No commercial relationship. Interactive Brokers is listed on editorial merit and has no input into this description or its scores.
