Quote from OldTrader:
A whopping $2.50 extra when you change an order??? An extra charge I might add which could have been avoided either with a market order, or a limit order with the limit set somewhat higher above the existing offer.
Ever had this one happen? Put your trade in at the offer....get filled on a quick 200 shares, and the price moves away immediately, and not just .01 away, to a point where you don't want to make the trade. IB charges $2 for the trade. I don't see how they make a dime on this trade personally. But in any case, there are any number of places with a minimum ticket charge...like the one you mention for $7 (or higher).
Not sure really what your point is here. Chances are if you compare IB with many of the other competitors, it's cheaper....ESPECIALLY if you know how they work their charges, and simply alter your trades to fit their system. But if it is not, then you should change.
Personally, I'm thrilled with the commission structure, along with all the other advantages that IB offers.
