Ehlers, complements the "reflex" indicator. Sources: * [rengel8](https://github.com/rengel8) (2021-08-11) based on the implementation from "ProRealCode" (2021-08-11) * [prorealcode](https://www.prorealcode.com/prorealtime-indicators/reflex-and-trendflex-indicators-john-f-ehlers/) * [traders](http://traders.com/Documentation/FEEDbk_docs/2020/02/TradersTips.html) Parameters: close (Series): ```close``` Series length (int): The period. Default: ```20``` smooth (int): Super Smoother period. Default: ```20```` alpha (float): Alpha weight. Default: ```0.04``` pi (float): Ehlers's truncated value: ```3.14159```. Default: ```3.14159``` sqrt2 (float): Ehlers's truncated value: ```1.414```. Default: ```1.414``` offset (int): Post shift. Default: ```0``` Other Parameters: fillna (value): ```pd.DataFrame.fillna(value)``` Returns: (Series): 1 column Note: John F. Ehlers introduced two indicators within the article "Reflex: A New Zero-Lag Indicator” in February 2020, TASC magazine. One of which is Reflex, a lag reduced cycle indicator. Both indicators (Reflex/Trendflex) are oscillators that complement each other with the focus for cycle and trend. rNg{Gz?gn! @g9v?)indexrfillnaT)inplace TRENDFLEX__trend) rrmaxr to_numpyr)rr r3shiftr4namecategory) r+r,r-rrrr.r/np_closer$s r( trendflexr?'sT62 &F 62 &F UC/!3 4E } % &E r7 #B % 'E f F~~H (FFE2u EFF7FO F%++ .F{f%6 fX& 5vhaxq8FKFO Mr*)NNNNNN)numbarnumpyrrrrrpandasr pandas_ta._typingr r r pandas_ta.utilsr rrr)r?r*r(rFs1155== D6"&*.+/ H HH H'H H!)H  H#+ H  Hr*
