I'm wondering if commissions were taking into account in their stats.
Cause, option strategies are not cheap comm wise.
I don't know about OA's comm structure, but e.g. Tastyworks is pretty cheap - $1/lot, $10 max/leg, no closing fees. Lots of other places do $0.60 per. If you're a veteran, TradeStation has their "Salutes" program which is commission-free (outside of exchange and assignment fees, of course.)
