Is a excel plugin. With end of day data feed.
It is the poorman's and I mean poorman's Optionvue.
But if you are not trading a huge portfolio that requires real-time analysis it works really well.

Thank you for bringing up Optionstar.
Optionstar does provide realtime spread
risk graph analysis and many complicated
strategies such as calendars and butterlies.
Best of all, as you colorfully pointed out.. it is much
more affordable than OptionVue bringing
you free delayed datafeeds from 4 different sources
and one realtime streaming with an ib account.

Well, since you "<i>strongly recommend Peter Hoadley's Options Strategy Analysis Tool (OSET)</i>", I think it would be helpful to explain how you use it so we can better understand why you feel so strongly.
Some examples would be helpful.
