Hello,
Recipe:
1. Replace all
Zig( array, value, % )
with just
Zig( array, value )
2. replace
ValueWhen( Nth, array1, array2 )
with
ValueWhen( array1, array2, Nth )
3. Replace
Ref(C1,-1)=0
with
Ref(C1,-1) == 0
Best regards,Tomasz Janeczkoamibroker.com

get stuck. You will find that AFL is not that different from the MS formula
