<SPAN

plot shapes at points on the chart or indicator where your code triggers a
"True" value.

would
trigger a buy at the crossover of the 50 day moving average. This would be
automatic. What you suggest is drawing an arrow like you would draw a trend
line.
<SPAN

<SPAN
class=135200318-21022003>placing the first 2 lines of code in the guru
commentary would plot the arrows on the price plot. Copying the buy and
plptshapes lines to the top of the builtin Price indicator window would also
plot the arrows on your price plot.

which off sets
the plot 1 atr below the low on the price chart. Not sure why perhaps some one
else can chip in here

quickly. I am a new user and I've been having some trouble getting

indicator with the code for plotshapes, I got a syntax error after the
"buy,". I entered a buy value above the line of code you gave me and
then got a syntax error on "plotshapes". HELP!! Assuming that I
eventually get this working, wouldn't it be easier to have arrows placed on
the drawing menu so that this could be clicked on the chart just like the
text box, rectangle/ellipse etc?ron> Ron,> yes you can
