Indicator Name: Adaptive Relative Vigor Index
(Cybernetic Analysis)
Function Name: Adaptive Relative Vigor Index
Format: ExtFml( "ADSI.RVI", Periods)
Input 1: Prices. (suggested input is Median
Price)
Input 2: Cybernetic Cycle Period, Homodyne
Cycle Period, or one of your choice. This indicator is much
like the adaptive indicators from ASI, and therefore, it can
take a period input that was not generated by an Ehlers method.
NOTE: this indicator takes the period input and then uses half
of period at each bar for its internal calculations, since this
is the recommended technique. Therefore, unlike ASI indicators,
the user need not take half of the period value before passing
it as input to the RVI function. This is done in order to stay
consistent with Ehlers' implementation in his book, Cybernetic
Analysis for Stock and Futures.
Formula 1.)
periods := ExtFml("ADSI.CyberCyclePeriod",
MP(), .18, .05, 1.1);
ExtFml("ADSI.RVI", periods);
