Ehlers Center of Gravity Oscillator [LazyBear]

As part of my "Ehler's Indicators week", here's one more.

CG Oscillator, by John Ehlers, provides a smoothed, essentially zero lag oscillator for identifying market turning points. The "CG" in the name of the oscillator refers to "Center Of Gravity" of the prices over the window of observation.

Entry/Exit are based on the osc/signal crossovers. Enabling the "Color bars" options helps in easily identifying crossovers.
