[amibroker] Help please ... How to code correlation of index to share

["Andrew Smith" <andy_kovacs@xxxxxxxxxxx>]

Hi folks. 
 
Got stuck with AFL ...
 
Lets say I have several groups set up, and each 
group contains a bunch of shares, plus a corresponding index. For 
example:
 
Group    Shares    
                
    Indice
<FONT face=Arial 
size=2>1            30 
Dow shares            
^DJI
2        
    100 Nasdaq 
shares      ^NDX
3        
    100 FTSE shares        
^FTSE
4        
    30 german shares        
^GDAXI
 
How can I set up an indicator that will plot the 
correlation of the current share to the indice associated with that shares 
group? For example:
 
corr=(c,close from index in current share's 
group);
<FONT face=Arial 
size=2>plot(corr,"correlation",colorblack,styleline);
 
Any sneaky way to code this without using 20 
nested iif's? I have 20 groups....
 
 
Thanks,
 
Andy
