Betfair Market Efficiency

    I've thrown a few quid on the Goose for this week's Celtic Manor Golf (quality player - not a very strong field). Did it with high st bookie as they were 10/1 and it was only the same with Betfair (and then there is commission).

    Just now I was checking on BF and you can lay him at 9.5 while he is still a general 10/1 to back with the bookies.

    I would expect these arbs to be hoovered up almost instantaneously so why aren't they?
    (My modest means and the 5% commission wouldn't make it worthwhile for me but I would guess there are bigger punters with lower commssions and larger bankrolls).

    Thing here is to put both prices in decimals.

    Current best bookie price on him is 11.0

    Current lay price is 10.5 over on Betfair.

    If you stuck a grand on him at the bookie and layed him at 10.5 you would get exactly a grand back with a standard 5% rate (assuming he loses).

    But if you had a rate of say 3% it would equal a guaranteed profit of €19.10 on a €1000 bet.
