Frans,
If it is only the sum of a condition over a fixed period, linked to
your AA-settings, you could use Sum:
Startbar = lastvalue(valuewhen(Status("firstbarinrange")==1,Barindex
()));
Lastbar = lastvalue(valuewhen(Status("lastbarinrange")==1,Barindex
()));
Cond = C>0;
Lookback = Lastbar - Startbar;
Tot = sum (Cond, Lookback);
Tot is now an array, so if you need to know the exact value of it on
the final bar of your test, use:
FinalTot = Tot[LastBar];
