How to read the different odds formats
Every format describes the same outcome price, but expresses the potential profit, required stake or market probability differently.
Fractional
Shows net profit relative to the stake. 3/2 means three units of profit for every two staked.
Common in: the United Kingdom and Ireland, especially horse racing.
American
A positive number shows profit on a 100 stake; a negative number shows the stake required to win 100.
Common in: the United States and North American sportsbooks.
Hong Kong
Shows net profit per unit staked. 1.50 equals decimal odds of 2.50.
Common in: Hong Kong and Asian horse-racing and football markets.
Indonesian
Positive values work like Hong Kong odds; negative values show the stake needed to win one unit.
Common in: Indonesia and some Asian betting platforms.
Malay
Ranges from −1 to 1. Positive values show profit per unit staked; negative values show the stake needed to win one unit.
Common in: Malaysia, Singapore and some other Asian markets.

Common in: betting analysis, market comparison and value assessment.
