How to read BetIQ price comparisons

Compare the same wager

A meaningful comparison requires the same event, market, selection, line or point, period, and applicable grading rules. Different point spreads or overtime rules are different wagers.

For a two-outcome market, both outcomes must be accounted for. A three-outcome market also needs the draw. Missing outcomes cannot be treated as impossible outcomes.

“Best” means the best price BetIQ observed among the displayed, reporting, eligible, comparable sportsbooks at the stated time. It does not mean every sportsbook in the market was checked. Review the coverage and exclusions alongside a comparison.

Stake, potential profit, and total return

Stake is the amount risked. Potential profit is the amount gained if the wager wins, excluding the returned stake. Total return includes both the returned stake and that profit.

• With decimal odds D and stake S: potential profit = S × (D − 1)
• Total return if the wager wins = S × D
• Conditional price difference = potential profit at the compared price − potential profit at the named reference price

A positive difference is additional potential profit only if this identical wager wins. It is not an expected earning or a prediction. A comparison needs an explicit stake, reference sportsbook and price, exact market identity, and snapshot time. An example stake is educational, not stake advice.

These formulas describe a standard cash wager at its stated odds. Fees, promotional credits, voids, pushes and special settlement terms can change the result. The sportsbook controls final price acceptance, limits, account eligibility, geolocation, and settlement.

Quote age and unavailable data

BetIQ reads stored observations supplied through The Odds API. Updates are periodic and constrained by the feed budget; a page load does not guarantee a newly fetched price. Use the displayed quote age and observation time, and verify the final price at the sportsbook.

A source that did not report is not the same as a source with an unfavorable price. Stale, incomplete, unsupported, or unavailable data is not evidence that no other price exists. An unavailable feed is also different from a search with no matching games.

Observed prices can change between collection and use. Comparing timestamps from different observations does not establish that both prices were simultaneously available.

Market-implied estimates and normalization

Decimal odds D imply 1 ÷ D. This is a conversion of a quoted price, not an independently measured chance of an outcome.

For a complete set of mutually exclusive outcomes from the same comparable market, proportional normalization divides each implied value by the sum of all implied values. The resulting normalized market-implied estimates sum to one.

This “no-vig” calculation is a mathematical convention. It does not reveal an outcome’s actual probability, eliminate uncertainty, or prove that a wager is profitable. Different normalization methods and different input books can produce different estimates.

Price history has limits

A line-movement chart shows recorded observations, not every price offered between them. A valid closing-price comparison needs an identical market and a verified pre-start reference; an in-game price cannot substitute for that reference.

Durable, frozen closing-price reporting is not yet complete. Do not assume that every event has a verified closing quote or that a missing comparison means zero change. A historical price difference does not predict future results.
