David H,
Here's some AFL which works pretty well for the
Bow Tie.
Another set of conditions could be addedto
absolutely ensure the medium term average crosses above the longer term ma -
similar to cond1.
I'll add when I have a little more time and
repost.
Another condition that would be useful to check
would be
cond5 = close < ma(close,180);
This would ensure you're picking up stocks that
have long term potential.
I like the stocks this picks up. Add some rel
strength comparison criteria and it looks a goer.
