Decimal odds
Decimal odds express the total return per unit staked, including the stake — 2.50 returns 2.5 times the stake.
Decimal odds are the European standard and the cleanest for computation: multiply stake by the price for the total return. They convert directly to implied probability (1 ÷ price), which is why data products favour them.
A normalised feed presents odds consistently so a product is not juggling fractional, decimal and American formats from different books.
