Ken,
Two things: 
1. The possibility of variable period in Aroon expressions offers 
unlimited coding ease, the coder fantasy is the only limit.
2. AFL is ...a bit better from the heroic period when Tomasz wrote 
his AFL Library code, any investment in Amibroker evolution is more 
than sucessful.
I have never used this indicator, I hope you will give us some 
brilliant ideas after your homework.
