by Ray Steele

• Q1 This program is great and way too cheap. Is it ok for me to send extra money when I register?

• Q2 What are the formulas used in the functions?
• A2 There are, of course, several. Click here to view a formula sheet (sheet shows formulas without dividend adjustment).

• Q3 What about !Options on other platfoms?
• A3 Unlikely to happen. My expertise lies in Excel and Windows. Although the add-in "should work" on a Mac, I have not tested this and will make no claims concerning it.

• Q4 What are the differences between version 2.1 and 2.2?
• A4 The Friday3 function was added. The algorithm for the implied volatility was rewriten for improved speed. Error messages were redone to conform to Excel defaults.
