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.

Creating a bar chart


In this example, we'll learn how to plot a histogram of a distribution generated by Math.NET. Histograms are useful to visualize statistical data and get a grip of their properties. We'll use a simple normal distribution with a zero mean and a standard deviation of one.

open System
open MathNet.Numerics
open MathNet.Numerics.Distributions
open MathNet.Numerics.Statistics
open FSharp.Charting

module FSharpCharting2 = fsi.AddPrinter(fun ch:FSharp.Charting.ChartTypes.GenericChart) -> ch.ShowChart(); "FSharpCharting")

Next we'll create the normal distribution that will be used in the histogram:

let dist = new Normal(0.0, 1.0)
let samples = dist.Samples() |> Seq.take 10000 |> Seq.toList
let histogram = new Histogram(samples, 35);

Unfortunately, Math.NET and FSharpCharting is not compatible out of the box. We need to convert the histogram from Math.NET to use it with the Chart.Column function:

let getValues =
    let bucketWidth = Math.Abs(histogram.LowerBound - histogram...
