OK, I can see the logic of making, in essence, a
new static variable for each bar of interest. But aren't these static
variables completely lost at the end of the day? I'd like to be able to
mark the bar permanently with the information, so that I can backtest it over
time. Also, using static variables and/or selectedvalue() are problematic
for me because they are not conducive to plotting the trades over
time. And AA simply can't deal with them. What I want to do is to
write the information into an array....
It seems to me that there might well be an internal
function that allows this....all that's really necessary is to create a dynamic
table with datetime() and whatever other values one wants to save. It's
just like the data plugin writing to the data table as bars come
in.
I'm looking forward to Mike's solution
too.

Yes,
that is what I tried to explain... you place your cursor on the selected bar,
which identifies its X-datetime position by way of the
SelectedValue(DateTime()). You save the trade information something
like staticvarsettext("Trade"+DateTimeNum,
OrderType+Numtostr(TradePrice,1.2). You set the OrderType and TradePrice using
param(). Then in your plotText() loop you compare this variable name to the
DateTim in the loop, if it matches you PlotText(...
staticvargettext("Trade"+DateTimeNum),...). Most of the time the staticvar you
are reading return empty, and you don't plot anything.
hope
this helps...perhaps i miss something

That's not quite what I need.
Say my guru tells me to buy at 11:12 tomorrow
AM. I'd like to mark that bar with a buy, and remember that it is a
buy. So i'd like to be able, on the fly, to mark a bar with a signal
and perhaps a price, and to save it for later use.
Thanks

If you haven't done so, have a look at the PlotText(), this
allows you to place text anywhere on the chart. It gives an example of how
to display the words "Buy" and "Sell" and price next to the bar. Also look
at the VarSetText() and VarGetText().
To add text to the selected or lastbar you would use the
SelectedValue( barIndex()) or LastValue(BarIndex()) as the name for
your StaticVar in which you store the info you want to show. When looping
you read the barindex() for each bar, set BI = barIndex() and in your loop
use BI[i] to look for a non-empty static variable.
At the start the system can read a simple text file and transfer
them to StaticVar. At the closing of the system you can use a
ParamTrigger to load and save the parameters to a simple text
file.
Hope this sketchy info helps...

I would like to add something to my trading
that I have not yet found to be available. Basically, I'd like to be able to write my own
information onto a bar in real time (for instance a manually-entered
trade entry or exit), and to do this from the chart
window (parameters menu). This information should remain
available in a hard disk file when AB closes.
I'm
thinking I need to create a dynamic array table of some sort that also
gets written to disk and which contains both the date/time code and the
new information. I know that there is the OSAKA plugin which
seems to do something like this, and perhaps that is my best
option? Alternatively, I could write to a foreign ticker, but
I'm not sure that's possible from the chart menu.
Any advice appreciated....
thanks
