What do all these numbers mean? Each box on the Betfair screen shows the odds (top) and the amount available (bottom) at that moment in time. Prices aren't locked in place, nor is the amount of money available, because bets are being offered and matched all the time.
Betfair Horse Racing Multiples enable you to place accumulator type bets on Horse Racing markets. You can combine up to eight legs into a single accumulator. You can also place Each Way bet where you are placing a separate win and place Multiple on your selections.
