Ryan, I've got the code running using the new quantmod, although it's outputting blank bitmaps.  As soon as I remove the underscores and run the old code it runs fine.  Am I missing something?

Thanks.  That explanation makes sense, although it's still annoying.  I used to have everything in a relatively easy piece of code which could bring back whichever market I wanted all in one go with little manual effort.

The name code works, ta.

    chartSeries(x,subset='2011-01::2012',TA="addVo();addMACD()", name = epic_char)


I've just updated my install to 3-13, but it's still keeping 3-9... am I being really dim?

Somewhat contrary to common sense, index components are usually
legally controlled by its respective owner/creator.  The result is
that it becomes illegal to make the list 'available'.

Obviously this varies, and I am not a lawyer, but that is the likely
reason behind the inability to download.  There are likely ways around
this of course...

With respect to chartSeries, I am working on getting chart_Series and
it's related add_ functionality 'complete', that is so one can
transition from chartSeries to the new version (which during the
transition will be called chart_Series, note the underscore)

Since you are only using addVo and addMACD here, you can do
chart_Series and add_Vo, add_MACD and will get much prettier graphics.
They will also be able to be embedded in standard layout() and
pars(mfcol= type layouts. i.e. the full graphic with panels etc
becomes one graphic object (like plot()).  Again, prettier and more
useful.

W.r.t the name of the chart, try name=
