Actually I've been researching them this morning after I read your post from 2 months ago. I trade deep in the money options so i usually only purchase 1-3 contracts. At $0.70/ct and no base fee, Interactive Broker looks like a viable broker for me. Need to research and think hard on whether I want to re-learn a new platform though
Even with the potential inactivity fees, it still looks viable. Paying $7.50 quarterly for my IRA is no bueno but still will likely save my money after accounting for reduced commissions over time
