re: eto charts for andrew Andrew, I've hooked up my Marketcast, matched it with some of Hoadleys excel functions.Hoadley's stuff probably would have saved you 6 months (but its often a road that must be travelled).I use the probability of a price occuring at expirey (or any time before expiry) quite a bit.If your interested http://www.hoadley.net/options/develtoolsaddin.htmPeter is the one that supplies most of the options free tools for the ASX web site, so its definately not cheap toys stuff (but the price is right as well).have to like playing with numbers to get the most out of it though.
