It's a shame I wasn't using the september contract as I might have ended up the day 3.75 points since on the last trade at 1:30 it went up 2 points on this one but not the june contract. Oh well. I'm switching over to the newer one for tomorrow.
What you are saying does not make sense. On a *relative* basis there isn't going to be a significant difference in movement between the two contracts otherwise arbs would come in and scoop up the free money.
I understand that there isn't really a difference but there was a .25 difference on that time frame between the two respective contracts. The September contract had a high that was .25 higher than the June one.
