 | _tdFATL (Fast Adaptive Trend Line) which practically shows the mathematical expectation of Close on any bar; _tdSATL (Slow Adaptive Trend Line) The meaning of the SATL indicator is to be mathematical expectation of FATL. The increasing line of SATL corresponds to the bull trend on the market and decreasing SATL corresponds to bear trend; _tdRFTL (Reference Fast Trend line) describes a response of the digital filter on the discrete sequence of market prices but with delay equal to Nyquist interval of the filter used in FATL; _tdRSTL (Reference Slow Trend line) describes a response of the digital filter on the discrete sequence of market prices but with delay equal to Nyquist interval of the filter used in SATL; _tdFTLM (Fast Trend Line Momentum) shows the momentum of FATL and is calculated by equation FTLM= FATL-RFTL; _tdSTLM (Slow Trend Line Momentum) shows the momentum of SATL and is calculated by equation STLM= SATL-RSTL. |
