Hi HHP,
It's an old problem in MS - it calculates all expressions BEFORE checking where IF
condition will take off to. By the way, it results in a huge inefficiency of
explorations, and all other studies in MS. Equis knows about it for a long time,
but prefers to ignore the issue. As for the division error, what I do in similar
situations is like this (taking your formula)
X:= If(H=L, 0, (2*C-H-L) / ( Abs(H-L)+0.000001);
It's up to you how many zeros put into 0.000001 :-) . For prices I'm happy with 5 after
the period.
Cheers, Vitaly
