Quote from Option Trader:
The broker I mentioned has amazing execution speed, price improvement, and top quality customer service e.g. e-mail response time and flexibility for the customer needs.
No such $15 OptionsXpress fees. The option rates for my group's volume get as low as $.50. They offer price improvement as well.
Among browser based brokers, I think OptionsXpress is the best; but this company is a Direct Access broker, who are in a league by themselves. E.g., at least with this company I found it safe, quicker, and more reliable to leg into spreads, then to place the orders as spreads with OptionsXpress, as you have 4 order boxes in front of you, and within seconds you can do one order after the other (after first watching if the bid/ask flow changes). I traded over 50k option contracts in a month on their platform placing spreads, and never a problem legging in.
If you need sophistication and research amenities, although they are good, IB is better; otherwise the above is a neater system.
