This market awards 25 points to the winning team of a test match, 10 points to both teams for a draw and 0 points for a loss.
You can bet on either team to perform better or worse than their prediction. This market is updated as the match progresses.
For example at the start of a Test match between England and New Zealand, SportingIndex might price England at 16-17.5 on the Win Index. Put another way SportingIndex have them as strong favourites to win the match.
If you thought England could justify this favouritism you would bet high at 17.5 for your chosen stake, in this case, £10 a point. If England confirmed your view and went on to win the match they would have been awarded 25 points and New Zealand 0 points. Had you gone high at 17.5 you would have made 7.5 times your stake: (25 - 17.5) x your stake = 7.5 x £10 = £75. However had you gone low on England at 16 then you would have lost 9 times your stake: (16 - 25) x your stake = 9 x £10 = -£90.
New Zealand, on the other hand, might have been priced at 5-6.5 at the start of the same Test. If you had gone high at 6.5 it would be important to note that both a draw and a New Zealand win would be profitable for you.
