Chi, I'm always finding this site highly educational and almost always if I take enough time to under some rocks, the answers are readily available. That being said, I'm fumbling here regarding the peak to trough. Any help, as always, is appreciated. Also, many thanks for the reconfirmation that you've posted regarding Wave 5. Many thanks and best wishes for a joyous holiday season. p.
