The TT Uncovered configuration window provides the user with configuration options in creating a synthetic quote.
Auto Disabled
When Auto (6) is unchecked, four additional fields appear:
A. Delta Range – The number of steps above and below the Delta, each as large as the Delta Step Size, used when creating the set of covered spreads.
B. Delta Step Size – The step size of the delta used when creating the set of covered spreads. Example: if Delta is 3, Delta Step Size is 2, and Delta Range is 2, the app will attempt to create covered spreads for all specified reference prices with the following deltas: -1, 1, 3, 5, 7.
C. Reference Price Range – The number of steps above and below the Reference Price, each as large as the Reference Price Step Size (in ticks of the underlying future), used when creating the set of covered spreads.
D. Reference Price Step Size – The step size of the reference price ticks used when creating the set of covered spreads. Example: if Reference Price is 0’12 (and the instrument ticks in increments of 0’01), Reference Price Step Size is 3, and Reference Price Range is 2, the app will attempt to create covered spreads for all specified deltas with the following reference prices: 0’06, 0’09, 0’12, 0’15, 0’18.
The graphic below shows two further examples of how the reference price range and step size parameters interact, and the total number of covered spreads generated in each case.
