Re: [amibroker] buy sell arrows

Thanks Tomasz I will have a look at those but as 
you can see form other posts the formula does delivery results (volume 
spikes)
but for some reason ami (well my version) is 
erratic is the display of the arrows sometime there the other times there not 
?
I'm going to try a re install of ami to see if that 
can fix it

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)
