 WHAT'S THIS?  
This is a REAL mathematically approach of an  ORDINARY LEAST SQUARES LINE FITTING SLOPE  as TradingView currently don't have a native one embedded, neither as a pine function.  Other "Sope" indicators from this linear regression model I found on public library are currently based on "momentum" rather tan slope.
Any modifications or additions are quite welcome!
Cheers!
