I haven't experienced the problems that tymjr has. While IB has had delay problems on the quotes both yesterday and today, the executions have still been perfect. As I mentioned, I use RealTick for the charting and timing of my trades on ES. I place both limit and stop orders and they executed at the proper times and prices, without any slippage, even though the IB quotes were off.
Of course, if I'd have had all the problems tymjr mentioned, I wouldn't be too happy with IB either, but my experience has been very positive.
