Is it possible to improve the functions UDF

[bines]

Hello everyone ,

These functions built a few years ago, can improve them?
These functions calculate the option prices.
They call and put options , computers all options in range,
I work with Excel 2010.

Functions are red font.

Thank you ! G.xlsm

A little shorter, but not much in it. Uses x as the OptQnt index rather than using a separate counter that needs to be incremented.

Hi TMS ,

Thanks for your help !

If I give up on multifly , and enclose it in a cell on a sheet, is that it is better in terms of speed?

Better to use 2.71828182845904 instead of the function EXP ?

I'm not sure what that sentence means. multifly is the 5th parameter passed to each UDF and, in each case, it has a fixed value of 100.

Not sure what you mean about putting it in a cell.

No idea if it will improve performance. If it's a fixed value of 100, I don't see why it needs to be double but, if all the parameters are doubles it's probably better to be consistent so that there are no conversions.
