[amibroker] Beginner: Variable Value of "BarCount" in indicator calculation

["mmike8090" <mmike8090@xxxxxxxx>]

Hi,

I had the intention to count all days that are trending according to 
Aroon-Indicator Definitions and write down the result to the 
interpretation area.

I made  the following script and to my surprise I get variable values 
of BarCount and all depending calculations. 
For example if I mark the Chart in the Year 2007 Barcount shows the 
Ammount of 217000, in the Year 1962 Barcount is 159000. Furthermore 
the same results (159000 and 217000) occur in in different stocks 
with different length of hostory.

I am can´t find the error/reason for that way of calculation.
I hope that somebody can help me. Thanks a lot!

MMike

PS: Heres the script

// AROON_COUNTER.AFL 

//
// INITIALIZATION OF PARAMETERS AND VARIABLES
//
P = ParamField( "Price field" );
Period = Param("Period", 14, 1, 200, 1 );
TrendDays=0;
AllDays=0;

//
// AROON INDICATORS
//

LLVBarsSince = LLVBars(L, Period) + 1;
HHVBarsSince = HHVBars(H, Period) + 1;

Aroon_Down = 100 * (Period - LLVBarsSince) / (Period - 1);
Aroon_Up   = 100 * (Period - HHVBarsSince) / (Period - 1);
Aroon_Osc  = Aroon_Up - Aroon_Down;

//
// COUNT TRENDING DAYS
//

for( i = 0; i < BarCount; i++ ) // Loop through all bars
    { 
      AllDays++; // Count all days
      if	(Aroon_Down[i]>=70  AND Aroon_Up[i] <=30 OR
    		 Aroon_Down[i]<=30 AND Aroon_Up[i] >=70)
      	{
    		TrendDays++; // Count Aroon trenddays
    	}
    } 

result = IIf	(((Aroon_Down>=70  AND Aroon_Up<=30) OR 
		 (Aroon_Down<=30 AND Aroon_Up>=70)), colorLime, 
colorBlack);
	
Plot( Close, "Price", result, styleCandle );

printf("Aroon Down \n");  
WriteVal( Aroon_Down ); 
printf("Aroon Up \n");  
WriteVal( Aroon_Up ); 
printf("Aroon Osc. \n");  
WriteVal( Aroon_Osc ); 
printf("All Days \n");  
WriteVal( AllDays ); 
printf("Trend Days \n");  
WriteVal( TrendDays ); 
printf("Aroon Trend Days \n");  
WriteVal( TrendDays/AllDays ); 
printf("BarCount \n");  
WriteVal( BarCount ); 
printf("BarCount-1 \n");  
WriteVal( BarCount-1 );
