I have a really interesting question from Plamen.

 Do you think that the money we see in the last three odds 1 minute before kick-off / at the Betfair / can give us a guideline what are the expectations for the final result?

It’s a known fact that over the long term that Betfair closing odds (or Betfair SP BSP) are highly accurate. But this is something we discussed in the question about overbet runners. LINK

However, in Football there is a more dominant bookmaker. That’s Pinnacle.
Pinnacle claim that if you can beat their opening prices by 1.5 points you win in the long term.

My answer here may seem a bit lazy. But to be perceftly honest, if you can find reliable and well written information from someone who knows more than you about the subject in question. It would be wrong not to bring attention to that.

So first is this article may Pinnacle themselves Market Movement in Betting
The 2nd link is from Football_Data.co.uk Article I though it was very well-argued and very useful.

I hope this helps understand your question. My thanks for asking it.

Cheers
Steve
