As Mrtools explained, the OCN NMA SD is a Bollinger Band using Jim Sloman's "NMA" Moving Average. The NMA smooths prices (adaptively) by using Momentum Weighting to capture the market's "natural" rhythm.

Cynthia Kase's Kase Peak uses Volatility-Normalized Momentum and is designed for finding overbought and oversold trades.

Basically, in Mladen's version of the NMA, it follows price closely when the momentum is strong and when momentum is low, it'll smooth more slowly. It's like a self-adjusting Moving Average.

The Kase Peak looks for peaks (or momentum exhaustion) whenever momentum exceeds limits as explained in the PDF that Mrtools posted.

Was there something about the two indicators that made you think they were sort of the same?

PS: Here's a mock up chart. You could set the OCN NMA SD to a create a channel as seen below by reducing the SDup and SDdown to a lower Standard Deviation like 0.5.
