Hi, becareful.
I'm not too familiar with Betting Exchanges, so could you be kind enough to answer my questions?

From reading your postings I am under the impression that if someone backs a horse at a certain price and then lays it at 6% below the "backing" price, then you are guaranteed a 1% profit after Betfair takes their 5%? If so, should this be a guideline for those of us with no Betting Exchange knowledge?

One can currently back New Zealand to win the Cricket World Cup on Betfair at $13 while on Twoflys they are at $8.10. I assume N.Z could be backed to win on Betfair and then laid on Twoflys (even at $12)for a guaranteed profit?

Thanks.
Michael
