Hi John,
The code that I posted (way back in 2001!) used a much more primitive version of AFL (still state of the art for that time.. ;)). It works as it is published, but only as an exploration. There is no exits included in the code, which is why you will get only buy and short signals, and only when Exploring, not in Scan mode.
I cut and pasted the code to the AFL editor, clicked Explore, and it still works as it did originally...

Hope that helps,
Daniel
