[EquisMetaStock Group] Re: Envelope of an Oscillator

["Jose Silva" <josesilva22@xxxxxxxxx>]

Normalization code adapted from formula found at
http://www.metastocktools.com :


===========================
Normalized Edson Oscillator
===========================
---8<---------------------------------------------

{ Normalizes indicator to -100% ~ +100% boundaries.
  From: http://www.metastocktools.com }

{ User inputs }
plot:=Input("plot:  [1]Indicator,  [2]Oscillator",1,2,2);
pds:=Input("Indicator periods",1,2600,21);

{ Indicator - Edson's oscillator example }
Ind:=fml("AAA");

{ Normalize indicator to historical highs/lows }
Oscillator:=(Ind-Lowest(Ind))
 /Max(Highest(Ind)-Lowest(Ind),.000001)*200-100;

{ Plot:
  Indicator on chart, oscillator in own window }
If(plot=1,Ind,Oscillator)
