Well, hi there partner,
There is some code for divergence in the AFL library.
I noticed it there the other day but I didn't open the files.
Depending on your idea of a peak/trough I have used simple code to
identify peaks and troughs in the past (don't get too excited, I'm
not a programmer just a hungry trader).
I have also measured the relationships between peak-peak and trough-
trough and backtested without any problems.
In a post a while back JohnR (I think) gave some code for
peaks.troughs that isn't forward looking (suitable for backtesters)
while I posted a lookforward one for use in charts as a visual aid
only.
My backtest suitable code is similar to Johns.
I kept away from zigzag etc but there is usually more than one way to
skin a cat.
Anyway, the forum eats that stuff for breakfast.
*I know nothink!*
.....but I am up to work on it with you as you use it while I am a
skeptic so that is a good combo.
Brian.
