Ehlers Corona Indicators

These are the Corona Indicators originally created by John Ehlers.

They are meant to identify cycles in the market and help you determine whether or not the market is currently suitable for trading cycles. They develop the corona at times when the signal is weak or unstable.

For those who are interested, all of them are based on cycle extraction using a DFT variant.

In general, Fourier analysis is not suitable for use on financial timeseries since it is based on the assumption of Stationarity. In the DSP world that restriction is commonly relaxed to include WSS signals (wide sense stationary). Ehlers seeks to approximate a WSS signal by detrending the data with a high pass filter before the DFT step, whether or not that is a suitable approximation is questionable as it ultimately depends on the specific data being processed.

What is certain is that they look very cool, so try them for yourself and see if you find them useful
