Can you make on your own your own arbitrage betting in betfair?

Question by Bob G: Can you make oneself your own arbitrage betting in betfair?

Anyway, thanks for the answer John. Best answer:

You can lay whatever bet you want, regardless of whether a person takes your bet is an additional matter. It requires two bets to set up an arbitrage so there's a chance that you will be left with an incomplete arbitrage.
