AFL Help request

["pacific5_au" <pacific5_au@xxxx>]

Hi folks,

I am trying to add a simple filter to a system to stop entry into a 
position where the moving average is dropping or going sideways, but 
other criteria have been met.

I am trying to say todays EMA is greater than the EMA of 15 days ago.

This part is not working :

AND (EMA( Close, 21 ) > EMA( Close, 21 ),-15);



Any help will be appreciated.
