Events and markets
An event is a question, such as where a rate will settle or who will win. Its markets are the tradable outcomes, each with a Yes and a No side.
An event’s page
The top of the page shows the event’s average spread and open interest, and Event Ended once it’s over.
The chart depends on the kind of event:
| Event | Chart |
|---|---|
| One market | The market’s probability, with a Yes/No toggle |
| A ladder of thresholds, such as “above X” | Probability by strike, with an Over/Under toggle |
| Ranges, such as “between X and Y” | The distribution across ranges, with an Exactly/Not toggle |
| A spread between two outcomes | Probability by spread |
| A numeric outcome | Expected payout, with an Expected Payout/Inverse Payout toggle |
| Several outcomes | Each outcome’s probability, as a bar or pie chart |
