[amibroker] Re: Intraday Intensity Indicator

[johan sundström <johanskatt@xxxxxxxx>]

John Bollingers book is not a good example of how to present things in a clear and concise manner, especiallyon how indicators are calculated and what he means by 'normalizing' them.Intraday Intensity is referred to in at least four versions:
 
open form (cumulative sum):
II1=Cum( Nz( (2*C-H-L)/(H-L) )*V ); 
 
closed form (n-period moving sum):II2=Sum( Nz( (2*C-H-L)/(H-L) )*V ,n);
 
normalized by total volume - II% :II3=II2/Sum(V,n);
 
normalized with bollinger-bands - %b(II) :top=BBandTop(II1,40,2);bot=BBandBot(II1,40,2);II4=(II1-bot)/(top-bot);
 
 
At least this is my understanding of it after some pondering.Which version to use? I have no idea - a matter of taste i suppose.
Attached is a gif of II% and %b(II) applied to the same stock.
