Yes I know but how should I decide which odd provider to chose . And how do they know the score and what odds to offer ?
I believe the odds provider have a person sitting in each match or have a live feed of the match(which has to be before the television as the television stream is delayed) .
You should also know that they charge a very high amount around 400-1000$ per month. So the chances of having a person in the game live, is very likely.
