Interactive Brokers — where it wins, where it loses
Interactive Brokers wins on regulatory reach, entry cost. It loses on published spread. Its cost per ten lots is not confirmed, so it is left out of the cost ordering rather than estimated.
Column by column
The split
Two lists, no averaging. A broker that takes a column outright appears on the left of it; one that gets beaten on a column appears on the right. Nothing is scored into a single number, because a single number hides which side you actually care about.
Wins on
- regulatory reach
- entry cost
Loses on
- published spread
Cost per 10 lots is the EUR/USD spread cost of ten round-turn standard lots at the figure above, commission excluded. Where a broker publishes a "from" spread rather than an average, the comparison inherits that limitation — see the unconfirmed list further down.

These fields are not confirmed. They are shown as gaps, not filled in, and they do not feed any column of the matrix:
- spreadEurusd — IBKR charges commission on raw interbank quotes, so no comparable single spread figure is published
- Negative balance protection applies to UK/EU retail entities under regulatory rules; not verified for all entities
