<FONT face=Arial color=#0000ff
size=2>If i remember correctly I found the following code on Guppie's
site; it validates and colors the Zig to show when Zig is valid (doesn't look
ahead). For details goto the Guppie site - perhaps some kind soul can post the
URL - I don't have it handy. Actually, if you do a search on the Zig you'll find
a European individual who made quite a study of it and has several detailed
report posted on his web site - I thin it was the person who developed the
Validation routine - there are also numerous discussions around... I'm working
with limited Internet access and can't be more
specific.

Peak & Zig ZagExcuse me... Enter key on Subject
Line gets me too often.It is clear that Zig Zag *can* give unrealistic
test results becauseit looks into the future. This is documented. But
there is almost thecaveat *can* included in the caution.But are
there any known conditions where test results can be relied upon.For
example if a calculated trendline up to the current bar is morethan a few
bars old, and is linear for those past bars, and correlates(for lack of a
better word) with current bar close price, does thisnot perhaps mean
that an assumption can be safely made that futureprices have not yet
influenced the current trend?Regards,PhsstSend
