Sources: * [rengel8](https://github.com/rengel8) * J.F.Ehlers 'Cycle Analytics for Traders', 2014 * [Pandas TA Issue #350](https://github.com/twopirllc/pandas-ta/issues/350) * [Proreal Code](https://www.prorealcode.com/prorealtime-indicators/even-better-sinewave/) Parameters: close (Series): ```close``` Series length (int): Max cycle/trend period. Values between ```40-48``` work as expected with minimum value: ```39```. Default: ```40``` bars (int): Period of low pass filtering. Default: ```10``` offset (int): Post shift. Default: ```0``` Other Parameters: fillna (value): Replaces ```na```'s with ```value```. Returns: (Series): 1 column Note: The _default_ is more cycle oriented and seems to be less whipsaw-prune. The older version might offer earlier signals at medium and stronger reversals. Compared to TradingView, returns very close results but appears to be one bar earlier.
