craig, I disagree that the $4 fee will pay for your implication that IB misses stops. You are assuming that fills will be worse. Slippage with the IB stops is minimal and I'm certain comparable to yours. IB's data feed is direct from GLOBEX and the CME. What bad ticks are you talking about? Besides, do you think that the Group has no experience in filtering out garbage? To make things clear: 1. Stop limit orders at IB are encouraged but stop market orders are offered - the client can chose the type of order they desire. 2. markets fluctuate up and down - native stops may trigger a fraction faster but there is no guarantee of a better fill. An argument can be made that native stops also tend to bunch up and push the market further up in the instant they are triggered. 3. In any event, the point will become moot as IB should be moving the stops native to Globex if some new software supplied by Globex works as promised.
