Sorry I misread your post, you put in quotes and I thought that was the error message you got while running Ninjatrader. Most of the complaint about IB is their tick data, they have a thing called aggregated tick which decrease bandwidth and increase speed during peak trading session. since this thread is about Pivots in IB, It is kind of irrelevent.

My understanding of IB data (I've never used it) is that it's a "snapshot" of data rather than real tick data. So the data you're getting isn't tick by tick, but something like millisecond by millisecond, so each update to a 1 tick chart may be several ticks rather than one single tick. It may not actually be milliseconds, but it's a very short amount of time instead of tick by tick. In a fast market, this could make a difference in how you view price action. With Ninja, I use Zenfire, and I'm happy with it. I've heard good things about Esignal, and not so good things about tradestation, though I think it depends on your style.
