Any ex-spread compilers on the boards?
I would like to understand how the spread firms calculate their spread indices for the gg's.
Say it is a 50:30:20:10 index. How do they calculate the figures accurately? Do they use both the win and the place odds to compile these?
I notice that Spreadfair's prices seem to be linked to Betfair movements and a bot controls the price updates for them. Would this be a fair assumption?
I've seen the calculation for simple index markets somewhere, but can't remember how to do it. I think it is based on the total points available for the index, relative to the odds.
But I could be talking tosh.
