That’s absolutely not true. I personally know the guys who run Citadels option trading desk and they are highly ethical people. I actually saw one of them get confirmed into the Catholic faith 8 years ago totally by accident when attending a mass.Don't do it. They don't actually execute your trades. If you have a big winner, they just remove the position from your account. Citadel financial is their funding arm, and they have bribed all the politicians who might regulate them. Robin hood screwed a friend of mine out of a $75k winning option position. There is a class action lawsuit ongoing.
