Expiry Calculation Terminology
The terms listed below are used at 24option when we describe our methodology of calculating expiry rates:
Bid Price – the bid price refers to the updated market price that is used for selling an asset before the option expiry time.
Ask Price – the ask price refers to the updated market price that is used for buying an asset before the option expiry time.
Last Trade – this term refers to the last price that was paid for the asset prior to the expiry time.
Last Quoted Index Price – this term refers to the last quote price for an index before the option’s expiry time
For any reason if there is a break in the information stream so that no pricing data is received for the 60 seconds before expiry time, the data used will be the very first price quote after the option expires.
