hey Louis,
I said "relatively speaking" ;-) ... on the first equation... i never said the Black Model was simple

(besides, we're just talking futures contract pricing and Black is for options on futures--of course that's going to be more complex)

btw, that link you pointed to on Black ( agecon.uga.edu ) leaves out that one can approximate the cumulative normal density function (by using 5th order polynomials) ... tables be damned ;-)

[edit] on further inspection, i believe the formula's are a Wilcox variation of the Black model where the underlying is assumed to be normally distributed. (as per Natenberg's Option Volatility and Pricing)
