Mike, thanks for the input. I had tried that previously; tried again. It is
not working. Here is the new code:
// Test the MA crossover exploration... // long trades entry and exit
rules:MovAvg = BuySellBuySellFilter=Buy OR Sell; = = = = EMA( Close,
15);Cross( Close, MovAvg );Cross( MovAvg, Close );ExRem(Buy, Sell);ExRem(Sell,
Buy);AddColumn( Close, "Close");//AddColumn( MovAvg, "MovAvg"
);_TRACE("sell..."+ LastValue(Sell) + " buy..."+
LastValue(Buy));_TRACE("Close..."+ LastValue(C));_TRACE("MovAvg..."+
LastValue(MovAvg));
Here is the output from the trace log. Here, I just hit "Explore" several times
rather than run it on an interval:

(The consistent value for the Close is what the market is actually doing right
at the moment. That is an accurate dynamic value....)
In any case, I need to get it to print the array value and verify that the
arrays are working properly. This is really just a troubleshooting exercise
for a bigger project. Ultimately, I have array manipulations that I need to
run, for my trading system calculations, on a list of stocks using an
exploration from the Automatic Analysis window. In particular, I'm trying to
implement the "AutoTrade using an Exploration" code posted by Peter Kuskopf to
the KB, for my own trading system. I have been struggling with that, because
the buy/sell signals are not being generated. It appears that the root cause
of that problem is this issue of the user-defined arrays not being populated
when running the exploration under the AA window.
Ultimately, I want to monitor (RT) a large list of stocks for trade
setup/execute conditions, and autogenerate orders to my IB account. The code
posted by Kuskopf (meant to run as an exploration) seemed like the most
straigtforward way to do that. If anyone else has any suggestions for
a better way to do that, I would like to hear them.... I definately do not want
to have a zillion charts open to do it. The main reason I migrated from
Tradestation.
Thoughts, anyone?
Thanks. GB.

exploration...
Try passing a scaler to the _TRACE instead of an array. Since you are
interested in the most recent value, just use the LastValue function in the
trace:
_TRACE("sell. .." + LastValue(Sell) + " buy..." + LastValue(Buy) );
_TRACE("Close. .." + LastValue(C) );
_TRACE("MovAvg. .." + LastValue(MovAvg) );
