Thanks for all the replies. I was really wondering why the IB demo is so inaccurate although they say it's the same thing, just delayed. In anycase, it does look like I have a whole lot of studying to day. Thanks again.
That is true under normal trading conditions, but lately in these choppy and very volatile markets these spreads are widening..I have seen 2-3 tick wide spreads frequently for the past several days...
