Yes i've read it, took about 30mins, in short don't bother it conatins nothing that i didn't already know from surfing the web for a while. It's not worth the cover price and is aimed at a complete novice/idiot.
i ordered it (Introduction to Financial Spread Betting) from Amazon a couple of days ago, will take a month to arrive (as out of stock) but will let you know what i think once i've read it.
