  2. 2Review the equivalent probability and sportsbook odds.
  3. 3Compare prices only after considering fees and market rules.

Formula and assumptions

Probability = cents / 100. Decimal odds = 1 / probability. American odds are then calculated from that probability.

The conversion treats contract price as probability and does not include exchange fees, spread, liquidity, or settlement differences.
