As a RH user, the fact that this is possible really scares me that there will be intervention/repercussions and that Robinhood doesn't know what they're doing. Is it possible for the FTC (or whichever entity) to freeze these guys' operations? Should I liquidate and move all my shares elsewhere ASAP?
That said, the only thing RH really has going for it is their decent UI experience. Everything that else matters sucks: Customer support, terrible price fills, uptime, and apparently their ability to write software which protects the end user as we are finding out.
As an option trader on the side I moved to Tasty Works awhile back, the same team that made TD Ameritrade's Think or Swim software, and a company which runs a daily 8 hour show focused on learning for free.
