[amibroker] Coding Sector Rankings

["jamesfarrow2003" <jamesfarrow2003@xxxxxxxxx>]

Hello,

I am a fairly new AmiBroker user, and I am trying to code up a 
Sector Ranking tool. (Using FOR loops, which is inefficient)  My 
intent is to run this every so often and then insert the results 
into a trading system to help adjust positionscore and buy/sell 
indicators.  

Below is the code I am using.  However, when I try to run this 
forother than the current day, each day comes up with the same 
scores.  I believe it is probably due to the third FOR loop (which I 
founhd int he AmiBroker users guide), but I am unsure why.  Also, is 
there a way to use indicators like MACD on Foreign(ie not current) 
stocks?

Thanks in advance for any help you can provide,

James

      	x = Foreign( sym, "close");
		y1 = MA(x,3);   
       y2 = MA(x,10);
    
	if (x[BarCount-1] != 0) // Verify current symbol has data 
associated with it
	{

			for( m = BarCount-7; m < BarCount; m++ ) 
			{ 
				// Insert ranking rules here as 
if/else rules.
		  		if( x[ m ] > y1[ m ] )
               SecSum[m] = SecSum[m]+1;

      		NumSec = NumSec+1;
     	}

	SectorRelStrength = SecSum[m-1]/NumSec[m-1];
  
  AddTextColumn( CategoryGetName( categorySector, i), "Sector 
name" );  
  AddColumn( SectorRelStrength, "SectorRelStrength", 1.4 );
