Summary
Expiration Value
When a contract expires, an Expiration Value is obtained by reference to the Underlying Market according to the following rules:
- Sample the last 25 trade or midpoint prices in the Underlying Market
- Remove the highest 5 prices and the lowest 5 prices
- The Expiration Value is the arithmetic average the remaining 15 prices
In the specific case of contracts on Economic Events, the Expiration Value cannot be calculated as above; see Specs: Economic Events.
Settlement: Spreads
Spreads are cash-settled contracts with a variable payout that allow trading on the expected direction of the Underlying Market.
The Settlement Value is obtained by reference to the Expiration Value and the Floor/Ceiling Levels of the individual contract:
- Expiration Value ≤ Floor: Settlement Value = Floor
- Floor < Expiration Value < Ceiling: Settlement Value = Expiration Value
- Expiration Value ≥ Ceiling: Settlement Value = Ceiling
Spread contracts are comparable to traditional Call Option Spreads with strike prices equivalent to the Floor and Ceiling values.
Settlement: Binary Options
Binary Options are cash-settled contracts with an all-or-nothing payout that allow trading on the expected direction of the Underlying Market.
The Settlement Value is obtained by comparison of the Expiration Value and the strike price with reference to the condition specified in the contract.
- Expiration Value condition is achieved: Settlement Value = 100
- Expiration Value condition is not achieved: Settlement Value = 0
