AFL for Time based stop ?

["samgrayy" <samgrayy@xxxx>]

Hi all. 

Is there a way to implement a time-based stop in AFL 
I tried this .. but since there may be multiple buy signals during a 
trade I still see trades that last many more bars than 7 ..

Sell = BarsSince (Buy) > 7 ;

Thanks in advance,
