Sorry I wasn’t particularly clear, there are a few matches on the matcher at certain times of the day/week.
However for Bookies that are not on the matcher or when there are no close matches available I always manually look through the bookie odds and compare to betfair.
I should have asked what markets have the best odds that are close together, are there any particular times/days of the week.
I find that when you have a short favourite in a football match the odds tend to be quite close to betfair for the favourite. Its usually the correct scores and match odds.
Are there any other markets that give better matches?
