These settings allow you to select the options and underlying prices that are used for the options displays. You can also choose to use most recent settlement prices.
Use Most Recent Settlement Prices
When you click this button, the system disables the other choices and yesterday's settlement price is used. If the market has already closed for the day, then today's settlement price is used.
Yesterday
Select this button to use yesterday’s closing price.
No Filtering
Click this button to use the most current Bid, Ask, Last Trade, or Yesterday's Close as the operative option price.
Option price and Underlying price
Select the price type for both the Option and the Underlying price: Bid, Ask, Bid/Ask average, Last Trade, and Yesterday’s Close.
If more than one price is selected, the system uses the most current of the selected prices.
For example, if only Last Trade and Yesterday's Close are selected, the last trade appears as long as that trade took place in the current day's session. Likewise, if Bid or Ask is selected along with Last Trade, the most recent Bid or Ask appears as long as it is more recent than the last trade. If not, the last trade appears.
