Citadel securities is the market maker, Citadel is the hedge fund and doesn’t have access to data from the other side

Did they pinky promise not to access the data or are there some actual barriers in place?

It being illegal seems like a pretty big barrier to me.

That speaks volumes about your integrity. Good on you!

But it is not true.

I wouldn't be so sure about that. Also, even if people cross the barrier it doesn't mean it is not there or isn't big. But thanks for the compliment!
