Income

Subtype of Job Request

The income I received by holding the referenced tradable between the given spot date (denoted as 0) and the given horizon date T specified in
Horizon Date

It is also part of the PnL Explain table
PnLExplain Table that is produced in association with the key PnL Explain when a tradable is priced with the Advanced Pricing model input.

By default, the spot date equals the globally set trade date ( i.e. valuation date) that usually equals today's date.
But if the
As Of entry to the function Price exists, the latter date is then regarded as the spot date.
It is represented by the time 0 in the documentation context of
Advanced Pricing

Precisely, I represents an amount regarded as received at T and defined as the sum of the present values as of T of the tradable's cash flows CFᵢ occurring between 0 (excluded) and T (included).
Formally:
I = Σ(CFᵢ(Pᵢ/P))
where:
CFᵢ are all realized cash flows occurring at times Tᵢ such as 0 < Tᵢ <= T, as implied by the market information available at T
Pᵢ are the respective funding discount factors, i.e. the discount factors seen at 0 with maturities Tᵢ, as implied by the curve associated with the issuer supplied in
Fund Crv Issuer
P is the funding discount factor seen at 0 with maturity T, as implied by the curve associated with the issuer supplied in
Fund Crv Issuer

This definition is very similar to that of
Carry
The only difference is that the cash flows CFᵢ in the case here are NOT implied by the information available at 0, but represent the ACTUAL (i.e. realized) cash flows in the referred time interval.
It turns out, the calculation of I requires the prior knowledge of all fixings that affect the cash flows occurring at or before T
These must be provided to the function
