Struct ZeroLag 

pub struct ZeroLag { /* private fields */ }

ZeroLag Indicator

Based on John Ehlers’ “Zero Lag (well, almost)” The indicator acknowledgement that the EMA filter has an error term: Error = Price - EMA[1]. It introduces this error term into the equation in addition to the value of the new data sample, and applies a gain term to minimize the lag.
