[amibroker] Re: consecutive down days | looping

["DIMITRIS TSOKAKIS" <TSOKAKIS@xxxxxxxxx>]

Ed,
You could avoid your [nice] loop,

 tt = IIf(C < Ref(C,-1),1,0); 
for (i=1; i<BarCount; i++) { 
   if (tt[ i ] == 1 AND tt[ i - 1 ] >= 1) { 
      tt[ i ] = tt[ i ] + tt[ i - 1 ]; 
   } 
} 

Plot(tt,"tt",colorWhite,styleHistogram | styleThick); 
f=C<Ref(C,-1);
z=f*Sum(f,1+BarsSince(f AND Ref(f,-1)==0));
Plot(z,"z",4,1);

if this loopless solution is not complicated.

to do this. I wonder if it would be possible to avoid the loopings 
and just use AFL array based coding to do this. Any ideas?
