Creation

Syntax

IRTreePricerObj = finpricer(PricerType,'Model',model_type,'DiscountCurve',ratecurve_obj,'TreeDates',tree_dates)

Description

IRTreePricerObj = finpricer(PricerType,'Model',model_type,'DiscountCurve',ratecurve_obj,'TreeDates',tree_dates) creates a IRTree pricer object by specifying PricerType and the required name-value pair arguments for Model, DiscountCurve, and TreeDates to set properties using name-value pair arguments. For example, IRTreePricerObj = finpricer("IRTree",'Model',HullWhite,'DiscountCurve',ratecure_obj,'TreeDates',['jan-30-2018';'jan-30-2019']) creates an IRTree pricer object.

Input Arguments

PricerType — Pricer type

string with value "IRTree" | character vector with value 'IRTree'

Pricer type, specified as a string with the value of "IRTree" or a character vector with the value of 'IRTree'.

Data Types: char | string

Name-Value Arguments

Specify required pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: IRTreePricerObj = finpricer("IRTree",'Model',HullWhite,'DiscountCurve',ratecure_obj,'TreeDates',['jan-30-2018';'jan-30-2019'])

Model — Model type

HullWhite object | BlackKarasinski object | BlackDermanToy object

Model type, specified as the comma-separated pair consisting of 'Model' and the name of a previously created HullWhite, BlackKarasinski, or BlackDermanToy model object. Create the model object using finmodel.

Note

When you use a HullWhite model, the IRTree pricer uses the HW2000 algorithm [1].

Data Types: object

DiscountCurve — ratecurve object for creating IRTree and discounting cash flows

ratecurve object

This property is read-only.

ratecurve object for creating IRTree and discounting cash flows, specified as the comma-separated pair consisting of 'DiscountCurve' and the name of a ratecurve object.

Data Types: object

TreeDates — Dates marking the cash flow dates of the tree

vector

Dates marking the cash flow dates of the tree, specified as the comma-separated pair consisting of 'TreeDates' and an NLEVELS-by-1 vector of dates. Cash flows with these dates will fall on tree nodes. The TreeDates argument determines the number of levels, or depth, of the tree. List dates in increasing order.

Data Types: double | cell | datetime

Properties

Tree — HW or BK trinomial tree

struct for HW or BK tree

HW or BK trinomial tree, returned as a struct with the following properties:

• tObs contains the time factor of each level of the tree.

• dObs contains the date of each level of the tree.

• Probs contains a cell array of 3-by-N numeric arrays with the up, mid, down probabilities of each node of the tree except for the last level. The cells in the cell array are ordered from root node. The arrays are 3-by-N with the first row corresponding to an up move, the mid row to a mid-move, and so on. Each column of the array represents a node starting from the top node of a given level.

• CFlowT is a cell array with as many elements as levels of the tree. Each cell array element contains the time factors (tObs) corresponding to its level of the tree and those levels ahead of it.

• Probs contains the probability arrays. Each element of the cell array contains the up, middle, and down transition probabilities for each node of the level.

• Connect contains a cell array with connectivity information for each node of the tree. The arrangement is similar to Probs, with the exception that it has only one row in each cell. The number represents the node in the next level to which the middle branch connects to. The top branch connects to the value above (minus one) and the lower branch connects to the value below (plus one).

• FwdTree contains the forward spot rate from one node to the next. The forward spot rate is defined as the inverse of the discount factor.

• RateTree contains the interest rate from one node to the next.

Data Types: struct

TreeDates — Tree dates

datetime

Tree dates, returned as a scalar datetime or datetime array.

Data Types: datetime

Model — Model type

HullWhite object | BlackKarasinski object | BlackDermanToy object

Model type, returned as an object.

Data Types: object

DiscountCurve — ratecurve object for creating IRTree and discounting cash flows

ratecurve object

This property is read-only.

ratecurve object for creating the IRTree object and discounting cash flows, returned as a ratecurve object.

Data Types: object

Use BlackDermanToy Tree Pricer and Black-Derman-Toy Model to Price FixedBondOption Instrument

This example shows the workflow to price a FixedBondOption instrument when you use a BlackDermanToy model and an IRTree pricing method.

Create FixedBond Instrument Object

Use fininstrument to create a FixedBond instrument object as the underlying bond.

BondInst = fininstrument("FixedBond",Maturity=datetime(2029,9,15),CouponRate=.024,Principal=100,Basis=1,Period=1,Name="fixed_bond")

BondInst = 
  FixedBond with properties:

                  CouponRate: 0.0240
                      Period: 1
                       Basis: 1
                EndMonthRule: 1
                   Principal: 100
    DaycountAdjustedCashFlow: 0
       BusinessDayConvention: "actual"
                    Holidays: NaT
                   IssueDate: NaT
             FirstCouponDate: NaT
              LastCouponDate: NaT
                   StartDate: NaT
                    Maturity: 15-Sep-2029
                        Name: "fixed_bond"

Create FixedBondOption Instrument Object

Use fininstrument to create a FixedBondOption instrument object.

FixedBOption = fininstrument("FixedBondOption",ExerciseDate=datetime(2025,9,15),Strike=800,Bond=BondInst,OptionType="put",ExerciseStyle="american",Name="fixed_bond_option")

FixedBOption = 
  FixedBondOption with properties:

       OptionType: "put"
    ExerciseStyle: "american"
     ExerciseDate: 15-Sep-2025
           Strike: 800
             Bond: [1x1 fininstrument.FixedBond]
             Name: "fixed_bond_option"

Create ratecurve Object

Create a ratecurve object using ratecurve.

Settle = datetime(2019,9,15);
Type = 'zero';
ZeroTimes = [calyears(1:10)]';
ZeroRates = [0.0055 0.0061 0.0073 0.0094 0.0119 0.0168 0.0222 0.0293 0.0307 0.0310]';
ZeroDates = Settle + ZeroTimes;
 
myRC = ratecurve('zero',Settle,ZeroDates,ZeroRates,Basis=5)

myRC = 
  ratecurve with properties:

                 Type: "zero"
          Compounding: -1
                Basis: 5
                Dates: [10x1 datetime]
                Rates: [10x1 double]
               Settle: 15-Sep-2019
         InterpMethod: "linear"
    ShortExtrapMethod: "next"
     LongExtrapMethod: "previous"

Create BlackDermanToy Model Object

Use finmodel to create a BlackDermanToy model object.

BlackDermanToyModel = finmodel("BlackDermanToy",Sigma=0.14)

BlackDermanToyModel = 
  BlackDermanToy with properties:

    Sigma: 0.1400

Create IRTree Pricer Object

Use finpricer to create an IRTree pricer object and use the ratecurve object for the 'DiscountCurve' name-value pair argument.

BKTreePricer = finpricer("IRTree",Model=BlackDermanToyModel,DiscountCurve=myRC,TreeDates=ZeroDates)

BKTreePricer = 
  BDTTree with properties:

             Tree: [1x1 struct]
        TreeDates: [10x1 datetime]
            Model: [1x1 finmodel.BlackDermanToy]
    DiscountCurve: [1x1 ratecurve]

BKTreePricer.Tree

ans = struct with fields:
        tObs: [0 1 2 3 4 5 6 7 8 9]
        dObs: [15-Sep-2019    15-Sep-2020    15-Sep-2021    15-Sep-2022    15-Sep-2023    15-Sep-2024    15-Sep-2025    15-Sep-2026    15-Sep-2027    15-Sep-2028]
     FwdTree: {1x10 cell}
    RateTree: {1x10 cell}

Price FixedBondOption Instrument

Use price to compute the price and sensitivities for the FixedBondOption instrument.

[Price, outPR] = price(BKTreePricer,FixedBOption,"all")

Price = 705.2729

outPR = 
  priceresult with properties:

       Results: [1x4 table]
    PricerData: [1x1 struct]

outPR.Results

ans=1×4 table
    Price     Delta      Gamma        Vega
