Two Pole Super Smoother
Overview
The Super Smoothers are improvements over higher-order Butterworth filters. Only after reading about regularization did I realize that the Butterworth filter consists of finite impulse response (FIR) and infinite impulse response (IIR) components, and that the FIR component could be removed, leaving a nearly maximumly flat amplitude response in the filter passband. Not only are the desirable characteristics of the Butterworth filter retained, but several bars of lag are removed due to the removal of the FIR component. The result is the Super
Smoothers described.
For example, plot the Super Smoother and the two-pole Super Smoother using the same Period for each. You will almost immediately see a trading system jump at you from the crossings of the two lines.
To add the tool to your chart, select the tool from the Ehlers tool group, and left-click on the chart to add the tool. Optuma will then draw the tool on top of the chart.
