Re: [amibroker] buy sell arrows

["Tomasz Janeczko" <tj@xxxx>]

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 oneday 
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 using sum() 
function as in your original formula)
