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|
