And I am recommending you to keep your mouth shut on issues you have no clue about because you look stupid calling one of the top retail brokers Somali style.
The dude stated that he was with IBKR and his quotes were missing. And you've been banned for using racial and anti-semitic slurs.
And IBKR closed 200 lots of a SPX box during the ENE blowup when I had $300K open to buy. So no, don't tell me about their sophistication... or charging a $4500 req for a $4000 vertical.
