F# for Quantitative Finance

By: Johan Astborg

Overview of this book

F# is a functional programming language that allows you to write simple code for complex problems. Currently, it is most commonly used in the financial sector. Quantitative finance makes heavy use of mathematics to model various parts of finance in the real world. If you are interested in using F# for your day-to-day work or research in quantitative finance, this book is a must-have.This book will cover everything you need to know about using functional programming for quantitative finance. Using a functional programming language will enable you to concentrate more on the problem itself rather than implementation details. Tutorials and snippets are summarized into an automated trading system throughout the book.This book will introduce you to F#, using Visual Studio, and provide examples with functional programming and finance combined. The book also covers topics such as downloading, visualizing and calculating statistics from data. F# is a first class programming language for the financial domain.

Using FSharp.Charting

FsChart is a commonly used F# chart library implemented as a functional wrapper over the Microsoft Chart Control. This control can save you some work because there is no need for boilerplate code as in the preceding examples for Microsoft Chart Control. FsChart is also designed to work with F# and integrate better with F# Interactive.

The library can be installed using the Package Manager Console by typing:

Install-Package FSharp.Charting

Creating a candlestick chart from stock prices

Let's look at the code for displaying a candlestick chart of the same stock as used before (Oracle) with data from Yahoo! Finance. This time there is less boilerplate code needed to set up the charting. The main part of the program consists of downloading, parsing, and converting the data:

open System
open System.Net
open FSharp.Charting
open Microsoft.FSharp.Control.WebExtensions
open System.Windows.Forms.DataVisualization.Charting

To use FSharpCharting, first we need to set up the chart as...
