Payout is not probability
A binary options payout is the published return for a successful contract, not its probability of winning. A 90% payout does not mean the contract has a 90% chance of success.
Break-even math matters, and so does where the payout was observed. Broker homepages, platform screenshots, help pages, and comparison sites may describe different payout contexts, so the guide separates ordinary payout from selected-contract ceilings.
Ordinary payout shown for common contracts.
Highest published payout, often limited to selected contracts or strike settings.
The win rate needed to break even before costs, friction, and rule mistakes.
