Depending on the betting market, there are a few meanings for the term fixed odds. Implying that an event may be fixed, in favor of one side or the other, is not one of them. No matter the wagering option, standard or exotic, odds become fixed when a bookmaker accepts a wager. For example, if +140 is the accepted price on a moneyline bet and the number dips to +125 prior to the match, players who wagered on the +140 price retain that line as fixed odds.
