## C++ Programming with Applications to Finance

The aim of this project is to create a program in C++ that can be used to price path-dependent options of an underlying asset driven by a trinomial model discrete in time. The project is aimed at testing your knowledge from Term 2 of the course and must implement an object-orientated methodology.

### General hints and tips路径相关期权定价代写

• This project description contains all the properties of pricing path-dependent options on a trinomial model that is needed to complete this project. Further knowledge might make the project more interesting, but is not required, and will not give any advantage when completing the project.
• Read the submission instructions at the end of this document before starting work on the project.
• Read through all the tasks before starting work on the project. Tasks do not have to be completed in the order that they are listed here.
• You are free to recycle any code produced by yourself during the module. You are also free to use any code provided in Moodle during the module, provided that such code is acknowledged.

This project contributes 50% of your final module mark. The deadline for submission is 11:59pm on Monday, 9th May 2022. Credit will be given for partial completion of each task. Across the whole program, marks will be attributed to the readability and efficiency of your code, which will be awarded based on keeping a consistent coding style, sensible parameter names and indentations. Comments are encouraged (but need not be excessive).

### Trinomial tree approximation路径相关期权定价代写

The linearity of this stochastic differential equation means that it is often more convenient to model x directly rather than the stock price S itself.

Explicit formulae have been derived for many types of options (including put and call options); however approximation methods are needed to price many other options. One such method is the trinomial model. Let’s consider a trinomial model of the stock price in which, over a small time interval of length ∆t > 0, the log-price x can go up by ∆x > 0, stay the same, or go down by ∆x, with probabilities qu, qm and qd respectively. This is illustrated as follows.

The features of the continuous-time process can now be captured by the parameters ∆x, ∆t, qu, qm and qd. Formula for the transition probabilities qu, qm and qd can be derived by matching the first two moments of the continuous-time process in (1) and the trinomial process over the time interval of length ∆t, in other words,

### Generating paths on a trinomial model

For a trinomial tree with N time steps, there are 3N paths to 2N + 1 different end-nodes. One can construct a bijection between these paths and a set of arrays of length N consisting of 0’s, 1’s and 2’s, where a 0 corresponds to the underlying asset going down in price, a 1 corresponds to the asset keeping the same price, and a 2 corresponds to the asset going up in price.

For example, if N = 3 then the array {1, 2, 0} would correspond to an asset remain the same in the first period, moving up in the second, and moving down in the final period (ultimately obtaining its initial starting price). Each path can be assigned a number x ∈ [0, 3N − 1], corresponding to the end-point of the underlying asset. To help you visualise this concept, a figure has been provided in 1. You are welcome to use an alternative convention for coding paths, as long as it is clear what you are attempting.

### Pricing options on a trinomial model

The payoff C of a generic path-dependent option might depend on price of the underlying asset at expiry S(T), strike price K, and a barrier B (see options below for further description of the barrier parameter). Path-dependent options for a trinomial model can be priced by calculating the expectation of all possible payoffs at expiry with respect to the risk-neutral probability, where discounting is done with respect to the risk-free return, which yields

### Task 1: Import data using a custom class (15%)路径相关期权定价代写

The attached file StockDataMar2022.csv contains fictional stock data (S0, R and σ) for three car companies: Bentley, Tesla and Ford. Your first task is to create from scratch a custom class called ReadCSVFile, which reads a .csv file, and outputs the content to double vector< vector<string> > format, whose rows and columns represent the rows and columns of the .csv file. You should create the header and code files for this class from scratch. The class should contain the following,

• Appropriate private and public member variables,
• Getter methods (if necessary) to retrieve the necessary data.

You should display the contents of your vector by using a separate template function DisplayDoubleVector to display the contents of any double vector.

The actual layout of ReadCSVFile.h is down to your discretion. You should write your class according to the object-orientated principles of encapsulation and abstraction. It is recommended that you use <fstream> and <sstream> to aid reading the .csv file.

### Task 2: Generate path, prices and probabilities for a trinomial model (20%)路径相关期权定价代写

In this task, you must create a subclass for TriModel (provided) called TriPath, which contains three member functions,

• void PathByNumber(int x, int *path)
• void PriceByPath(int *path, double *prices)
• double ProbabilityByPath(int *path)

The header file for TriPath has been included. You should implement the constructor, above member functions, and any other member functions you see fit.

### Task 3: Write a pricer for a trinomial model (20%)

The class PathDependentOptions (included) contains two member functions,

• The virtual abstract function virtual double Payoff(double *prices, int N),
• The pricer function double PriceByExpectation (TriPath Model)

In this task, you should implement the PriceByExpectation member function in a seperate .cpp file, using the expectation described in equation (2).

### Task 4: Implement payoffs for exotic options (20%)路径相关期权定价代写

Now we need to implement the fixed price Asian, lookback, knockout and classic Parisian options, according to their various payoffs. Each option should be created as a subclass in the header file of PathDependentOptions and implemented in the associated .cpp file. Each subclass should contain appropriate private member variables, constructor and any other methods you see fit to include.

### Task 5: Price options for Tesla & Ford (15%)

In this task, you program should neatly display the price of options for both Tesla and Ford over a time period T = 1 and N = 6 time steps, using the fictional data for S0, R and σ you imported in Task 1. The strike, barrier and period-limit variables K, B and M for the Tesla and Ford derivatives are as follows for all options:

KT = 130, KF = 160,

BT = 160, BF = 200,

MT = 2, MF = 2.

The output to the console should be neat and easy to read for the end-user.

### Task 6: Create end-user documentation (10%)路径相关期权定价代写

Finally, you should create end-user documentation for your ReadCSVFile class and DisplayDoubleVector function ONLY. No programmers log is necessary.

Hint

End-user documentation should allow a user to read about your class/function and understand its function, inputs and outputs, without needing to know any of the internal workings of that class/function. It is not a description of algorithms, nor a description about how you programmed the class/function. The documentation should be created in Latex and included in the top-most directory of your project file.

### Submission instructions路径相关期权定价代写

#### Format

Submit the code as a single compressed .zip file, including all Code::Blocks project (.cbp) files (if you used Code::Blocks), data files (.csv), source code and header (.cpp and .h) files and the executable (e.g. .exe) file produced by compiling and linking the project, all residing in a single parent directory. The .zip file should preserve the subdirectory structure of the parent directory (that is, the subdirectory structure must be automatically recreated when unzipping the file).

The documentation files must be submitted in .pdf format and uploaded to Moodle in the top directory of the .zip file. It is advisable to allow enough time (at least one hour) to upload your files to avoid possible

congestion in Moodle before the deadline. In the unlikely event of technical problems in Moodle please email your .zip files to matthew.sparkes@york.ac.uk before the deadline.

#### Code usage permissions and academic integrity

You may use and adapt any code submitted by yourself as part of this module, including your own solutions to the exercises. You may use and adapt all C++ code provided in Moodle as part of this module, including code from Capinski & Zastawniak (2012) and the solutions to exercises. Any code not written by yourself must be acknowledged and referenced both in your source files and developer documentation. 路径相关期权定价代写

This is an individual project. You may not collaborate with anybody else or use code that has not been provided in Moodle. You may not use code written by other students. Collusion and plagiarism detection software will be used to detect academic misconduct, and suspected offences will be investiaged.

#### If things go wrong

Late submissions will incur penalties according to the standard University rules for assessed work.

It may prove impossible to examine projects that cannot be unzipped and opened due to file corruption, or projects that cannot be compiled and run due to coding errors. In such cases a mark of 0 will be recorded. It is therefore essential that all project files and the directory structure are tested thoroughly on your machine before being submitted in Moodle.

It is advisable to run all such tests starting from the .zip files about to be submitted, and using a different computer to that on which the files have been created.

All files must be submitted inside the zipped project directory, and all the files in the project directory should be connected to the project. A common error is to place some files on a network drive rather than in the submitted directory. Please bear in mind that testing on a lab computer may not catch this error if the machine has access to the network drive. However, the markers would have no access to the file (since they have no access to your part of the network drive) and would be unable to compile the project.
