Settle Value

Function Settle Value within Bond with keys Bond Settle Value keysreturns the settlement value of the referenced bond at a given settlement date Tˢ as a function of the clean prices.
Several values may be also returned here in the form of a 1D-array
This is based on the actual bond's notional (not scaled to 100) N(Tˢ) that applies at Tˢ
Note, the future cash flows are not considered in this calculation. The settlement value V(Tˢ) is calculated by the formula:
V(Tˢ) = N(Tˢ)Pᵈ(Tˢ) / 100
where
Pᵈ(Tˢ) is the dirty price at Tˢ, as implied by the given clean price at Tˢ

If no clean price is supplied, the settlement date cannot be specified and is assumed to equal the bond's spot settlement date.
Then the dirty price - and thus the settlement value as well - is calculated by discounting all future cash flows.
The latter discounting requires the input of a discounting curve.

If the settlement date Tˢ is not explicitly given, it will be set to the bond's settlement date as implied by a trade transaction assumed to occur on the trade dateT₀ (typically today).
