Whats happens to 09-07 at roll over ?

[kakakidan]

Hi,
The 09-07 DAX closed on Friday. I was trading live when it closed and was not able to get out in time.
I was short at 7763 and when 09-07 closed, it was at 7750. Since I did not close my trade, I called the provider and they closed it manually at 7766.
When I got my statement, it shows that it was closed at 7831. Now that is a big difference as compared to where 09-07 closed or where the trade was manually closed.
Any ideas?? I can talk to the provider only on Monday, so wanted to know if someone else came across something like this.
Take care.
Kaka

Kaka,

I would guess open positions at expiry would be rolled over.

Sep closed/expired at 7750. At 12:00 Dec was at 7834, at 12:01 it was 19 points higher at 7853 on heavy volume. Attributable to roll-overs or a news event? See attached .doc (scroll up the page) .
