Quote from deviltrader:
I use IB now and I've considered opening an optionshouse account. The $9.95 flat commissions applies to each partial fill. If you ever place large limit orders between the bid/ask, you know that you're likely to get a partial fill. I've had a single order filled as 3-4 partials, so in that case I'd be charged $30-40. The other thing that bothers me is their website doesnt seem very complete. The FAQ leaves unanswered questions. I don't think you can call yourself a serious options brokerage if you don't describe how margin is computed.
Hello. The OptionHouse ticket charge is applied per leg, per day. This means that if your 3-4 partials were all filled in the same day, you would be only be charged once, i.e. $9.95
