Re: [amibroker] buy sell arrows

["David Holzgrefe" <dtholz@xxxx>]

Well Tomasz the proplem has gone with d/l of ami 
3.45 from your site and the beta 3.49
 
and installed in a new location ...hmm maybe time 
for a cleanup 4 versions of ami on my hhd's  
 
Now back to the formula 

 
 volume > ma( volume, 260 );  
or  volume 
> sum( volume, 260 )/260;
 
How would I find stocks with a 20 % volume spike greater than the average 
?
 
Thanks David

Hello David and all,
 
You probably will  NOT get any signals 
from the formula volume > sum(v,260)/52 

because it gives "TRUE" result only if one day 
volume is 5 times bigger than 
one-year average (it is basically the same 
as : volume > 5 * ma( volume, 260 ) )
 
Such condition does not happen often (if 
any)
If you want to see if a one day volume is above 
one-year average of volume just
use:
 volume > ma( volume, 260 ); 

 
or
 
volume > sum( volume, 260 )/260;
 
(the second example shows the same usingsum() 
function as in your original formula)
