I was just having a look around the net trying to find a dummies explanation of Geometric Brownian Motion. I came upon this site which I thought was kinda neat. If you’re like me and understand things better if they are in spreadsheet form with XL formulas then this is quite helpful. Also has some sample code for retrieving stock data history from googlefinance or other data providers via webservices.
Thank you so much, just what I needed. Will check it from home tonight.
