Tradestation isn't the only one with prob's today.......IB was down for 2-3 minute stretches twice today, confirmed on both DSL & Cable, Hawaii and Texas. There would be a bottleneck on the floor if you were there too, I'm sure, especially during those annoncements.
Think about it, it takes a few seconds to work through orders that are all placed 2-5 seconds apart...then keep comin' for several mins. No sweat, that's the market!
