[amibroker] Help with simple AFL code

[michel_junior003]

Hi,

I want to identify stocks (Weekly) that have ADX(11) > 25

I used this code:

TimeFrameSet( inWeekly );
Filter = ADX(11) > 25;
AddColumn( Close, "Close " );
AddColumn( Open, "Open " );
AddColumn( High, "High " );
AddColumn( Low, "Low " );
AddColumn( Volume, "Volume " );
AddColumn( ADX(11), "ADX " );


Something is wrong because I see stocks that have ADX lower than 25. 
How can I correct this?
This code works well for Daily stocks, but doesn't work for Weekly stocks.  
Thanks in advance.
