I'm a HUGE believer in the Polynomial Regression Channel. If it's coded correctly, it's highly predictive for support and resistance. I use 2 of them on my charts. One is longer term (150 - 200 bars for daytrading), and one is short-term (50 bars). I only use upper and lower lines. I use one at full range for the multiple time frames of swing trading.
The only one I've ever seen coded perfectly and correctly is the one made by Robert Payne at www.funwiththinkscript.com - made for Thinkorswim.
Thank you very much for this. I will test it shortly.
