What is Indonesian Odds?

Indonesian odds are a betting format used across Asian books, quoted as a number whose magnitude is at least 1, positive or negative. The simplest way to hold it is that Indonesian odds are American odds divided by a hundred: American +250 is Indonesian 2.50, and American -150 is Indonesian -1.50. A positive price is profit per unit staked. At 2.50, one unit staked returns 2.50 profit if it wins — a price longer than even money, so an outsider. A negative price is what you must risk to win one unit. At -1.50 you stake 1.50 to win 1.00 — a price shorter than even money, so a favourite. The thing worth committing to memory is that this is the exact reverse of the Malay convention. In Malay odds a negative number is the outsider; in Indonesian odds a negative number is the favourite. Two Asian formats, both signed, both quoted to two decimal places, and the sign means the opposite thing in each. A price of -1.50 read as Malay and read as Indonesian describes two completely different bets, and nothing on screen will warn you. Conversion is straightforward once the direction is right. A positive Indonesian price plus one gives the decimal price, so 2.50 is decimal 3.50. A negative Indonesian price is one divided by its magnitude, plus one, so -1.50 is decimal 1.67. Check which format a book is displaying before comparing anything — it is usually a setting, and it is usually not the first thing a new account defaults to.
