When applied to racing this quite simply means lay bettors bet against a horse winning a particular race.
In this context conventional Trading on a selection is described as back Trading.
Our Corporate Trading Exchange
For this process we use the biggest betting exchange as our corporate Trading exchange of choice, as it is the world leader in Trading transactions of this type. the exchange requires punters making lay bets to pay out their potential losses when making a bet.
The amount is then matched by another person on the Trading exchange, who is also required to pay out the potential loss, should the other persons selection wins, they get paid but if any other horses on the race wins we get paid.
