It’s the largest financial penalty ever ordered by FINRA, which oversees brokerages. Robinhood neither admitted nor denied the charges in the settlement announced Wednesday. In a blog post, Robinhood said it has improved support for its customers, including the ability to call in and talk with a service representative for some issues.
