"I want a composite that shows signals only for days
when there are both buys and shorts ..."
Yuki,
Why "a composite" ? This would make things complicated.
The solution could be
1. Create first the composites
Buy=...;
Sell=...;
Short=...;
Cover=...;
AddToComposite(Buy,"~buy","v");
AddToComposite(Short,"~short","v");
2. Then, in IB
b=Foreign("~buy","v");
s=Foreign("~short","v");
Plot(b,"Buy signals",colorBlack,1);Plot(s,"Short
signals",colorWhite,1);
Plot((b*s!=0)*(b+s),"Sum of Buy+Short signals",colorRed,2);
the red bars will give you the sum.
3. Back in your AA,
b=Foreign("~buy","v");
s=Foreign("~short","v");
Filter=b*s!=0;//explore current stock, all quotations
AddColumn(b,"Buy signals",1.0);
AddColumn(s,"Short signals",1.0);
AddColumn(b+s,"Sum",1.0);
you may see the signals for the requested days.
