I'm about to start trading ES in real time for the first time. I have a question or two, since I've been practicing on IB's demo system and I noticed a few things that can't imagine reflects the actual market. 1. What's the typical spread? Is it 0.5-0.7 normal, or should it be closer to 0.25? 2. IB seems to report more bid/ask changes than actual trades? Would there normally be more than 4 trades per minute, or less? 3. Sometime there would be spike in the bid/ask like 784/806... Do spikes like these happen often? If so, can we safely disregard them? God I sound like a newbie. But I guess I am in ES., so I figure I might as well ask for some advice, as there are lots of ES traders here. Thanks.
