Key TAGs | Excel Index | API Index



Generates a new simulation path given a IRStepMonteCarlo() object.

Returns a three column array.

The first column is the stochastic fixing rates the second column are the stochastic discount factors and finally the last column contain the accrual factors.

Each row is the path that the process has taken over time.

An accrual factor is a stochastic factor that you would multiply your payoff by.

You then discount your payoff by the discount factor at the forward date (last date within the 'MandatoryDates' parameter stored within the IRStepMonteCarlo() function or the last date within the range returned by the IRMCDiscounts() function.

).



Note: Within Excel, the function is named - CT.PRO.IR.MCNextStep

Example Inputs

The first column represents the name of the parameters. The second column specifies whether the parameters are optional or not. Finally the last column provides some sample input data.
Function call input string-keys are always in the format : "NAME.EXTTAG.TICKER" The "EXTTAG.TICKER" part is determined from the output of other, capetools, object creation functions.

Example function usage


The C# example below contains all the sub-function calls leading up to this function call. As a result, the example can contain a lot of code.

The VB.NET, J#, C++.NET, Java, Excel VBA, Visual Basic 6 (via COM) and C++ examples below contain function code stubs for the calls leading up to this function call. However, the function call for this function is displayed.
You can easily reproduce the stub functions code from the C# example.


If you are accessing this functrion via the MiniXL libraries, this function is present within the CT.QL.Simulation20 MiniXL Excel Addin.

Within our Excel Example Addin Generator, we have used the following QuantTools sub-functions in order to prepare the arguments needed to call the IRMCNextStep() function. If you are executing this function via the MiniXL libraries, the module addin name, (in brackets, to the right of the sub-functions listed below), indicates the MiniXL library in which the sub-function is held. You will need to load this library into your Excel session (along with any other libraries that the sub-function call within the addin requires (ie - CT.QT.Utils20 addin in almost all cases) in order for the example to compute successfully.

These are the financial QuantTools sub-function calls that are used within the examples :





The objects generated by these sub-functions are inter-connected in the following way :
