A price is not a prediction. It is a claim about how likely an outcome is, with a fee built in, and everything else about betting is easier once that one sentence is doing its work. The habit to build is not picking winners but reading a price closely enough to know whether it is generous.
What the decimal actually says
Boards in Serbia quote decimals, and the one at Mozzart does too. The number is a multiplier on the stake, including the stake itself. A 200 RSD ticket at 2,50 pays 500 RSD — 300 RSD of profit plus the 200 RSD you staked. At 1,50 the same stake returns 300 RSD. That is the whole notation, which is why decimals compare most easily across markets.
One division turns it into a probability
Divide 1 by the price and you have the chance being quoted. A price of 2,00 is 50 per cent. A price of 4,00 is 25 per cent. A price of 1,25 is 80 per cent.
| Price | Implied chance | Reads as |
|---|---|---|
| 1,20 | 83% | Heavy favourite |
| 1,50 | 67% | Clear favourite |
| 2,00 | 50% | A coin toss |
| 3,50 | 29% | Live outsider |
| 8,00 | 13% | One in eight |
This is the whole technique. Convert the price, then ask whether you genuinely believe the outcome is more likely than that number. If the honest answer is no, it is not a bet, however strong the feeling about the match.
Where the margin hides
Add the implied chances across every outcome of a market and the total always comes to more than 100 per cent. A three-way football market priced 2,00 / 3,40 / 3,80 converts to 50 + 29,4 + 26,3, which is 105,7. The 5,7 above the hundred is the margin, which is why a bookmaker need not predict anything to make money.
Two consequences follow. A market with a small overround prices better throughout, and that usually means the main football lines rather than the exotic ones. And the margin is why breaking even means beating the price, not just being right more often than not.
Comparing two prices on one match
A side at 1,45 and the same side on a different line at 2,60 are not a cautious and a bold version of the same opinion. They are two bets with two requirements, and the second needs something to happen that the first does not. Convert both, estimate how often each requirement is actually met, and take the larger gap between your estimate and the implied chance. When neither gap is convincing, the match is not a bet, and accepting that is worth more than any single pick.
What a moving price tells you
Prices move for two reasons, and the two are not equally informative. News moves a price and carries information with it: a first-choice keeper ruled out on the morning of a match is a real change to a real probability. Money moves a price with none, and weight of public money on a popular team is the commonest case of all. The direction of travel says what the market thinks it has learned, not who wins.
Once a price is readable, the question is what to do with it: a single, a combination or a system, which is the ticket-types guide. Prices behave differently once a match is under way — see live betting — and the rest of the section sits on the betting hub.
