I use MotiveWave to see if this indicators is useful for whipsaws. I also confirm if I can use it within TA-Lib. I also introduce how the Hurst Component can be useful to see if a calculated time series is trending or mean reverting. Personally, this stuff matters!
If this turns out to be useful, all charts generated will be part of my Analytics service
