Volatility Voicemail: Listener questions and comments

Comment from Roger Barone: If they did so thru @IBKR their margin is $35,250,000. Anyone else ZERO! @IBKR SUCKS! @CBOE REFUSES to stop their MARGIN ABUSE! @SEC_News...Yes. They charge a MINIMUM OF $150 on ANY VIX SPREAD even if a long one like that. THEY TOTALLY SUCK! I told CBOE at Pinnacle but no action. Read this and this.
