Quote from schulzey:
Between not getting some orders even filled, and a tick difference on sells, buys, and breakevens I think it will make a substantial difference on my bottom line. I'm starting to realize that the demo doesn't really show what it's going to be like at all unless you're trading intermediate term where the spread makes less of an impact.
Quote from schulzey:
So just for the record, when you buy at bid or sell at ask, your orders never get filled unless it goes a tick above or below your asking price?
Quote from Laissez Faire:
I did not notice any difference between my fill prices on the simulator on Ninja and my real account with Interactive Brokers.
ES is generally very liquid, so I do not think you will get any major surprises when you go live. With less liquid markets, you may notice more of a difference.
