A clearer view of the market.
Read the price
Decimal odds of 2.00 imply a 50% probability. A stake of 100 at that price returns 200 if the selection wins, including the original stake.
One event. Many different markets.
Period, line, settlement rules and team orientation must all agree before prices can be compared. Native markets stay separate until that identity is verified.
Read the margin
Add up the implied probabilities of every outcome of one event. At a single sportsbook the total is above 100%, and the excess is its margin. If the best prices from different sportsbooks add up to less than 100%, the gap is an arbitrage. The implied probability calculator shows the margin, and arbitrage betting explained covers what the arithmetic leaves out.
Know when a price was seen
Imported snapshots retain their original observation time. They are useful for research, but they are not a promise that a price is available to trade now.
