I myself always wondered how IB could afford to provide streaming real time quotes and the insanely low commissions that they do to its retail customers without charging anything extra. For those with IRA's I can understand the concern about the new fee. But for anyone who is a regular trader, I don't see the reason to get worked up. If you're not making enough profits monthly to dwarf a $10 charge, then you might be in the wrong business. Also, while IB's $79 cost for Level II is absurd, it's a feature mainly geared toward active traders, who should probably be subscribing to an external data feed/charting package anyway and not using IB's level II. I think the knee jerk reaction to get upset over the $10/mo. is simply because we IB customers have had it so good for so long. However whatever shortcomings IB may be perceived as having ($10/mo., no interest etc) are more than balanced out by their commissions, and I'm sure that if you calculate the savings in commissions over just about any other retail broker, you'll find that it more than makes up for these things.
