Raman Support & Resistance Bands

The Raman Support & Resistance Bands tool was developed by Ed Raman and is used to assist with determining support and resistance levels.

This is a companion discussion topic for the original entry at https://www.optuma.com/kb/optuma/tools/levels/raman-support-resistance-bands

I’ve added these to a few charts and they look great. I googled how to calculate the bands and the only reference points to this article at the Optuma knowledge center. Is there a reference explaining the calculation?
