I use Sporttrade. Can you add them to this tool?
Sporttrade uses a version of implied probability. You can use Sporttrade odds and add a % to the end and it’ll use implied probability.
What vig-removal method are you using?
We use the Additive method of vig removal where both implied probabilities are summed together to create an overround. Then each individual probability is divided by the overround to remove the vig from each side. It is then converted back to the odds format you used.
What other methods of vig removal are there?
There is the Multiplicative Method, the Logarithmic Method, Shin Method, Proportional Method, and then Odds Ratio Method.
Which method of vig removal is best?
For two-way markets, like we have here, that are fairly close to the median, all methods are pretty similar. As you get into multiway markets and markets with very high or low odds, other methods have truer results. We plan to improve this tool in the future to allow users to choose the method of vig-removal they wish to use.
