What is Malay Odds?

Malay odds are a betting format used widely across Asian books, quoted as a number between -1 and +1. The sign is not decoration: it tells you which side of even money the price sits on, and it is the source of nearly all confusion about the format. A positive Malay price is read per unit staked. At 0.60, a one-unit stake returns 0.60 profit if it wins, which is a shorter price than even money — a favourite. A negative Malay price inverts the direction: at -0.60 you risk 0.60 to win one unit, which is a longer price than even money — an outsider. The magnitude never exceeds 1, because at exactly 1.00 the two readings meet and the price is even money. Converting to decimal makes it concrete. A positive Malay price plus one is the decimal price, so 0.60 is decimal 1.60. A negative Malay price is one divided by its magnitude, plus one, so -0.60 is 1 divided by 0.60 plus 1, or decimal 2.67. Implied probability then follows as it always does, from one divided by the decimal price. The reason to learn the format rather than always switching the display is that the switch is not always available and the arithmetic is not always identical. Rounding differs between formats and a converted price can sit a fraction away from the one the book actually settled at. Where a comparison matters, convert both sides to the same format yourself rather than trusting two interfaces to agree.
