[amibroker] Re: Position Score

["tipequity" <l3456@xxxxxxxxxx>]

Thanks, for the reply. Please read my question more carefully. I 
understand what positonscore is suppose to do. Lets assume that I 
want to use the value of a variable var1 as a tiebreaker to enter 
into trades, so I set PositionScore = var1;. var1 takes on values 
from -100 to 100. If I understand it clearly, positionscore uses the 
absolute value of var1. Therefore, var1=-100 & var =100 have the same 
absolute value as tiebreakers. So my question is twofolds:

1. Is the above explation true?

2. if so, what is the merit of positionscore using absolute value? 
specially when I can use postionscore = abs(var1).
