Thank you for your reply. A couple of issues though.
I looked at the documentation and saw the alpha
transperancy parameter, but for some reason I was
still getting the same results. Maybe I am missing
something very fundamental. If alpha is not provided
then the default is for the candlestick box not to be
transperant, correct? Even changing the alpha value
wouldn't produced desired results, I can increase
transperancy, but not eliminate it. I wasn't seeing
that since I can still see the lines (wicks) go
through the boxes that's why I asked here. Also, this
may be another foolish oversight on my part, but how
come when I have candlestick2(axMiddle, opens, closes,
highs, lows, width=4, colorup='k', colordown='r')
instead of getting a bar colored black when it closes
above the open price I get the opposite --- red? It
seems colorup should be black, colordown -- red as in
colorup : the color of the lines where close >=
colordown : the color of the lines where close <
As far as the moving average calculation, I did see
the disclaimer and didn't mean to be a stickler, it
just seem a bit misleading to me as I was trying to do
the Exponential Moving Average calculation and compare
the results to the actual financial charts. They
didn't match and I thought I would point that out.

Yes, the alpha argument to the candlestick plot
transparency. alpha is the traditional name for the
level, so look for it in documentation strings, eg

You can add these marks fairly easily yourself by
adding an additional
plot command, and using the marker style TICKLEFT or
other words, you can plot any kind of line you want
more or less. The
candlestick method may not support it directly, but
it is easy to
overlay. We should probably add a marker style
TICKCENTERX for this
kind of marker, and better add TICKCENTERY for
symmetry. It's only a
few lines of code that need to be added to the

I'm not attempting to make a financially meaningful
plot, but to
illustrate plotting techniques. You are free to do
over open, close, average or random data. As I note

Some of the data in the plot, are real financial
data, some are
random traces that I used since the goal was to
techniques, not market analysis!
