Two prices can be compared only after their event, outcome, unit, period, and settlement context have been reviewed.
Event identity
Check participants, competition, kickoff time, and orientation. A home/away swap changes the outcome mapping. A matching team name alone is insufficient to establish fixture identity.
Period and settlement
Football regulation 1X2 normally describes home, draw, and away at the end of regulation plus stoppage time. Read each operator's terms for extra time, interruption, postponement, voids, and abandoned events. Similar market titles do not establish identical payouts in every scenario.
Price units and fees
Keep decimal odds distinct from prediction-market token probabilities and bid/ask quotes. Include the applicable fee model, liquidity, and executable size before interpreting any gap. A team's NO contract can include both a draw and an opposing win.
Freshness
An unchanged price can be freshly confirmed. A recent delivery time does not prove a recent source observation. Read original timestamps, confirmation age, and explicit unavailable or suspended states.
Use the arbitrage calculator only after reviewing your inputs. See margin removal, API data semantics, and historical coverage.
