mini NQ and its bigger brother

I've noticed that during regular trading hours that there can be a large difference between the price of the nasdaq100 futures and the e-mini version. Can anyone explain to me why that is? Am I hallucinating?

 

and include time and sales, or time of day when you think this happens ?

there should be very llittle difference ...

see time and sales for the contracts at the CME website

"I've noticed that during regular trading hours that there can be a large difference between the price of the nasdaq100 futures and the e-mini version. "

 

Looks like just an issue with the 10 minute flash quotes on the CME web site:

NSDQ100 MAR03 1027.50 +100
E-NASDAQ MAR03 1002.00 -2450

Bad prices from the CME , q charts shows 1001.50 on the same delay for ND03h

 

You were looking at Globex data for ND and see the closing price of Globex ETH session (8:30 am CT). ND trading is done open outcry only since that time. No side-by-side trading for ND.
