Ehlers Elegant Oscillator using Trend Strength calculation

This is Ehlers Elegant Oscillator using a trend strength calculation, not really sure how useful it is yet though, but maybe worth testing.

What is the Trend Strength algorithm?

Mladen's "Trend Strength" algorithm is used to determine certain changes within an oscillator's reading and plotted and colored behind the main indicator's line as a secondary filter to help distinguish and plot entry points.

In most cases, the "trend strength" is calculated using a smoothed RSI but can be coded to be based off the primary indicator's readings.
