title: Are there known techniques to generate realistic looking fake stock data?
body: <p>I recently wrote some Javascript code to generate random fake stock data as I wanted to show a chart that at first glanced looked like real stock data - but all I came up with was <a href="http://www.scottlogic.co.uk/wp-content/uploads/2011/11/mockStockData.js">pretty noddy</a>.  I was just wondering if there are some resources that explain how this might be done "properly" i.e. so you get realistic looking data that has the same patterns that you see in real stock data?</p>
