I have calculated it before to see if I would win or make some money from it, but is not not working. From my calculations, I will definitely lose money. I have gone through all the odds on betting sites before and all I see is loss if I tried it. I do not now how it can be done because with what I saw, arbitrage betting is not possible.

maybe read this
