[amibroker] Coding Sector Rankings

[jamesfarrow2003]

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
