Hi Grant,
Are you in the Pacific NW?? If so, you might consider joining our
ABNW Yahoo! group ( http://finance.groups.yahoo.com/group/ABNW/?yguid=227868394 ) and
attend a meeting (we try to meet monthly, but like what the road to
you-know-where is paved with, that's only sometimes). Next meeting is this
Saturday, south of Seattle near Auburn. Lots of different levels of
experience so don't be bashful. Besides, it's fun to see what others are
doing with AB, the markets, computers, etc.
Peace and Justice --- Patrick

Patrick, you're awesome. Thank you so much, from one NW
trader to another. :-)

however it has yet to show up. Maybe I've been away so long that the
rules have changed, but no matter. I'll try again and just include
the code within the message. The following will plot the Average
Range as either points or percent of average Typical price (selectable
via the parameters menu (right click the chart, select Parameters in the
popup). Period for the average is also selectable in
Parameters. This uses a simple MA. MA variations for Exp, Hull,
etc. can easily be substituted, or added as parameter selectable
choices. > > One note on the code Brian provided: the
_expression_ H-L used in Midpoint returns the range for only the last bar
(day). As such, IMHO it is not useful for evaluating the
midpoint of each day in the average range period. And while I didn't
play with it much, I couldn't get it to function properly in an
indicator (my apologies Brian if I missed something). As such,
I find that either the MA of Close or Average [ (H+L+C)/3 ] array are
useful for an indicator such as I think you wanted. Below is the
code originally attached to the missing post, slightly modified to use AVG
rather than C for the % indicator. > > Enjoy. >
