[EquisMetaStock Group] Re: Jose - having trouble with Williams Osc

["Jose Silva" <josesilva22@xxxxxxxxx>]

I've plotted the indicator below on a Euro/USD 1-min chart, but can't 
see any problems.

pds:=Input("Normalizing lookback pds
 (1= historical Hi/Lo)",1,2600,150);

{ Plot 1: Price section }
PriceX:=C;

{ Plot 2: Indicator/Oscillator section }
IndX:=WillA();

{ Choose x pds or historical Price High/Low }
Hi:=If(pds>1,HHV(PriceX,pds),Highest(PriceX));
Lo:=If(pds>1,LLV(PriceX,pds),Lowest(PriceX));

{ Price normalized to 0~100% }
PriceNorm:=(PriceX-Lo)/Max(Hi-Lo,.000001)*100;

{ Choose x pds or historical Indicator High/Low}
Hi:=If(pds>1,HHV(IndX,pds),Highest(IndX));
Lo:=If(pds>1,LLV(IndX,pds),Lowest(IndX));

{ Indicator normalized to 0~100% }
IndicatorNorm:=(IndX-Lo)/Max(Hi-Lo,.000001)*100;

{ Plot in own window }
{PriceNorm;IndicatorNorm}
(IndicatorNorm-PriceNorm)/25
