Interactive Brokers is one of my favorite brokerage firms.
They consistently pay high rates on cash at rest in your account, share in the profits of loaning share for margin, and have a world-class API in place.
The downside, until now, has been that they charge commissions. Well, that’s why the news that IB LITE is coming is so exciting.
