Expiry Calculation

Expiry Calculation: Terminology

The following terms are used by highoption™ to calculate expiry rates for:

Bid Price – The last known price prior quoted by Data Provider for selling an asset prior to the option expiry time.

Ask Price – The last known price prior quoted by Data Provider for buying an asset prior to the option expiry time.

Last Quoted Index Price – Last quoted price by Data Provider for an Index prior to the expiry time.

In the event that there is no pricing data received 60 seconds prior to the expiry time then the data will be taken as the first quotation received after the expiry time

 

Expiry Calculation: Expiry Level

Expiry levels are calculated by highoption™ as follows:

Type Expiry Level Formula
Indices The last quoted index price that appears in the Data Provider field at the expiry time
Currency The sum of the bid and ask price / 2
Stocks The sum of the bid and ask price / 2
Commodities The sum of the bid, ask prices / 2

Expiry Calculation: Historical Data
