FTSE100 on IGIndex - rollover question?

Hi all,

I trade FTSE100 daily on IGIndex and therefore am subject to autoroll every day at market close. Usually my positions are closed and then reopened at a cost of 0.5 points. So a short position would close at 4100 and reopen at 4099.5.

Today however I was closed at 4164 and reopened at 4149.5. IGs explanation for this is due to the market value falling after dividends have been paid, but this seems a little extreme.

Does this sound correct to you guys?

Cheers

dont see why not. Just a market gap down ?

Yep that's perfectly valid. A future is priced based on interest rates and future divis. Once those divis have been paid the value of hte future drops.
