Ehlers Decycler Oscillator

The Ehlers Decycler Oscillator is a trading indicator developed by John F. Ehlers.

The goal of this oscillator is to eliminate very low-frequency components from the Ehlers Simple Decycler by using the half-period Ehlers Highpass filter and transforming the output into the oscillator.


The oscillator is calculated by taking the ratio of the high-pass output data to price then multiplied by a coefficient, which is equal to 1 by default.
You might want to adjust the coefficient if you plot several instances of the oscillator on the same pane.

The interpretation of the Ehlers Decycler Oscillator is that crossovers of oscillators with different coefficients can help identifying important trend reversals.

Example of usage:
decycle= decyclerOsc(100, 1.2); // 100 as period and 1.2 as coefficient
plot(decycle, "Ehlers Decycler Oscillator", colorRed);
