Sirry have never used it but looking at the code i have in my scripts folder
/* to use filters you should uncomment lines below
AA.ApplyTo = 2;
AA.Filter(0,"watchlist") = 3 ;
you needto remove the block comment from the lines
/* to use filters you should uncomment lines below */
AA.ApplyTo = 2;
// AA.Filter(0,"watchlist") = 3 ;
now set your filters for bars/dates and watchlist in AA
Have you set the correct path to your group of AFL scan files in this line
AFLFolder = "C:\\Program Files\\AmiBroker\\AFL";
Do the AFL files within this folder have actual buy/sell conditions?
