So far, optionsxpress has worked fine, altough they charge a bit high commissions: $1.50 per option contract. Interactive Brokers charge $0.70 per contract (less than half), altough its said they have a dismal customer service. They also charge inactivity fees, and there are some months when I dont place a single trade as Im a "seasonal" trader. Which gives better/faster fills on options? IB or OX?
