What I've figured out on this so far:

- for panels other than the main panel, using the 'legend' parameter for 
addTA will overwrite the label in the upper left corner of the panel.
- in the main panel, using the 'legend' parameter will write the legend 
on top of the Last value display, but they will be superimposed and 
unreadable

There does not seem to be a chartSeries/quantmod equivalent of the 
legend() function used for plot() that could name each series and 
provide a color coded key.
