Dave,
I'm running MS 6.52, and I don't see a double() function.
There is a PREC() function that deals with precision,
but it looks like it truncates decimal points rather than
expand (but I'll experiment a bit).
But, I think I found the real problem for the disagreement...
I was translating V1[6] from Easylanguage (which means
the value of V1 6 bars ago) to Ref(PREV,-6), but
it should be Ref(PREV,-5) since PREV references the
previous bar. When Corey supplied his solution, I tried
it out and got much closer agreement.
Thanks to all you folks (Dave, Corey, Brooke, any I missed?)
for all the help.
