Thanks Anthony for posting this again for all to see.
I've
used it as an indicator for quite a while now. Also,
this indicator
module has a lot of features,
where each feature could be a snippet.
How to Shade
How to plot a trendline from code
How to detect a breakout based on these
trendlines
How to plot support and resistance
etc.
IMHO..Each one a key concept not readily evident
from
the on line documentation and should be in
ABWiki..
Best regards
JOE
