Betfair Tennis trading - Scalping the serve on a Tennis match

if querrey would have lost this game the odds would have gone from 3.02 to 4.34. with 500 pounds in play this would have been a terrible loss (compared to the possible winnings). plus i really don't see how querrey has an 83.3% chance to win this game. where does this value even come from?

@ilDomski - It would be great if trading were one way traffic but every good trading strategy has to accept there is a balance to be had between profits and losses, so money management is always key. Most people consider direction to the be the most critical factor when trading but it often isn't. Even if the trade would have failed you had several options as to what to do next. But that's down to each individual. The chance of winning a game is calculated from the underlying market.

OPS.. Comment removed.. but I think your answer is exhaustive!

@tausentosh - With great difficulty. We use a very complicated algorithm to do it and iterate it to home in on the values. It's similar to the method used by odds compilers.
