I have been trying to get some sort of reaaduot for what the Stocknum is.
The help files don’t actually give much clue as to what it is and how
to access it. I have tried exploration and in title of indicator, but I only
get 0.
Cheers,
Graham

Hello DT,
You first have to do a transformation; vertical to horizontal. You can do
this by creating a barchart for the equities, and then analyze it just like
you would any indicator. Especially with looping you can now do almost
anything. The transformation looks like this:
In this case the equity for first stock from the watch list is plotted in
the last bar. You need just two lines of code to do this:
Buy = Cross( Close, EMA( Close, range ) ); // First four lines a dummy
trading system
Sell = Cross( EMA( Close, range ), Close );
Short = Sell;Cover = Buy;
E=LastValue(Equity(1));
Pointer = BarCount - Status("StockNum");
AddToComposite(IIf(Pointer==BarIndex(),E,-1e10),"~EquityTest","C",1|2|4|8);
// use Backtester
Equities = Foreign("~EquityTest","C");
Plot(Equities,"Equities",1,2+4);Title = "Equities for 100 N100 Stocks";
GraphXSpace=10;
Filter=1;
You can plot any kind of data this way and it will be permanently on disk.
Nice for system calibration files (make those zero based).
I think you can take it from here :-)
Best regards,
Herman.

Herman,
Stewart asked at
http://groups.yahoo.com/group/amibroker/message/38506
something simple : how to select the top5 of an exploration. Any idea
for this request ?
[If I understood well, to run an exploration
Filter=1;
AddColumn(MACD(),"MACD");
for 100 stocks and see in the result list ONLY the top5 MACDs,
nothing else]
I do not see how can I do it.
[I hope to avoid MAX(Foreign("~AAPL-MACD","C"),MAX(Foreign("~ABGX-
MACD","C"),...]
Any idea appreciated.
