Newbie asking a stupid question

This no doubt appears a stupid question to all you experts out there, but could someone explain to me why there is such a discrepancy between actual market indices and futures quotes with spreadbetting firms.
As an example, on Tradindex this morning, the CAC 40 daily future was quoted at being 4 or 5 points up, when the index is actually up around 30 points, yet the FTSE daily future accurately reflects the actual index (again at around 30 points up). I know futures are supposed to track the actual market so how come the figures can be so far out?
To confuse matters (for me anyway) further, although the CAC 40 figure says +5, the actual column quotes do accurately reflect the current market numbers - so why doesn't it say +30?
Doh

Try the "Search" facility and type in "spreadbetting." This subject has been done to death. Try the other tabs above such as "knowledge lab.etc" which will cover the subject. Good luck.

Thanks Neil; thought I'd read up on this but obviously not. Also thought, like many others in threads I have just read, that I was trying to guess the markets, not second guess the SB company.
And to cap it all, the Tradindex website is now down (for the second time in a week!).
Thanks again for the steer.

You are welcome. You may find the discussions swinging between biased spreads, dealing desks, and the merits of intra-day spreadbetting versus holding for several hours to several days plus. Good luck.
