Quote from gurucandidate:
I see there are indeed electronically traded CL options at IB. Good news.
I refereed to complexity in pricing options for option writers and defensive strategies which the author totally missed.
I imagine IB and other brokers took their time to implement CL electronic options because they tried to figure out how to assign client exposure to option spreads.
Calendar spreads, calendar butterflies and rolls in CL options carry futures-calendar risks. This does not in any way refute Black Scholes. It's simply another risk to price. If you're long the Feb-Mar 50 call calendar you would hedge a portion of your futures risk in shorting the Feb-Mar futures spread.
