PaulThanks, that clears that up. What is slightly odd is that those equations are most definitely not in my edition of "Paul Wilmott Introduces Quantitative Finance". Instead I've just got two second order approximations, with a corresponding p.mike
Only thing being, they're not in the errata, are they? Or was that post an erratum addendum to the errata? Thanks again, I can carry on digging through the book and writing some binomial code for myself. mike
Also, in the code on page 95, I assume that the lineS(j) = u * S(j-1)should actually be j+1, since j-1 in a loop from n down to zero won't work very well.
On p.627 of "Derivatives" is not the sign wrong on the middle term of A,B and C in (eq46.2) ? i.e. should not it be [ignoring sub/super scripts and greek letter] A= v1 * a - 1/2 * v2 * b B= -2* v1*a - c* dt C= v1 *a + 1/2 * v2 * bThat would make it consistent with case with dividends under section 46.11.1 which is consistent with http://people.maths.ox.ac.uk/~reisinge/ ... dNotes.pdfand "Option Pricing:Mathematical Models and Computation"

HiI am using the VBA code in page 948 ·67.3 americal call,implicit and it doesn't work at all.I suspect that anything is wrong because dS and ds appear in the same code.Anyone knows if there is a erratum of Part Seven numerical methods of Chapter 67?Thanks
