How to read football betting odds before a match

Odds are a price, not a prediction certificate

Football betting odds express a market price at a moment in time. They react to injuries, lineups, schedule congestion, public money, bookmaker risk and new information.

Implied probability

For decimal odds, a simple implied probability estimate is 1 divided by the decimal price. A 2.00 price is roughly 50% before margin. A 1.50 price is roughly 66.7%. Bookmaker margin means the full market usually adds up to more than 100%.

Line movement

When odds shorten, the market is pricing the outcome as more likely or more exposed for the bookmaker. When odds drift, the market price is moving the other way. Hermes should never claim why a line moved unless a source explains the driver.

How FootballGames10 should present odds

Use a timestamp, name the source or aggregator, compare the market with team news and expert views, and avoid phrases such as lock, banker, risk-free or guaranteed.
