This repository includes Pyhon and Julia modules and Jupyter notebooks for Monte Carlo simulation of mathematical finance models and instruments. It is intended for research and education purpose.

We provide a set of models that can be combined to form hybrid models for interest rates, FX and equities. Financial instruments are represented by individual payoff objects. The payoff objects are combined to form the contractual cash flows of the instrument.

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Recommended Python environment is Anaconda. This project is based on Python, Jupyter Notebook and Julia. Important Python packages are Numpy, Pandas and Plotly and QuantLib. Julia models are derived from Python implementations.

Clone the repository via:

git clone https://github.com/sschlenkrich/HybridMonteCarlo.git

Start Anaconda, open a terminal and navigate to the folder of the local repository.

cd [path-to]/HybridMonteCarlo/

Create a new Anaconda Python Environment with required packages.

conda create --name [envname] --file Requirements.txt

Activate the new environment via:

conda activate [envname]

Install Julia language from https://julialang.org/. Also install PyJulia; used to run Julia from within Python.

pip install julia

PyJulia may need to be configured in a new Anaconda environment.

python
>>>import julia
>>>julia.install()
>>>exit()

Install QuantLib library via pip (QuantLib is not available via conda).

pip install quantlib

Now start Jupyter Notebook with:

jupyter notebook

This step should open a browser window. Navigate to:

[path-to]/HybridMonteCarlo/doc/MonteCarloSimulation.ipynb

Finally, the notebook can be executed by selecting the menu item.

Kernel > Restart & Run all

Inspect the output and have fun.

There are currently no data files included in the project.

Models can be serialised and saved via pickle. We use this approach in the notebooks.

We use SemVer for versioning. For the versions available, see the tags on this repository.
