Hi Wayne,
I was about to try to capture a chart with the trading range, but you seem to have mastered it !!!
Shorten your time frame to 1 year, daily ....
I see two ranges ...
The Inner - 4.2 to 4.7 which has been holding since last Sept. except for three pokes above and below to the wider range of 4.0 to 4.89.
I look at the wider range/band to be the collection of failed attempts to break out of the "inner band/range".
See what you think ....
Thanks, Lee
