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.
