You'll have less trouble making the formula work if you stop trying to look into the future. F1 requires data from two bars into the future and so it's not surprising that MS stops delivering a result two bars short. Changing the code to look only at the present and the past gives a signal that is more credible in the real world (though obviously two bars later).
f1:= Ref(C,-4)+Ref(C,-3)-Ref(C,0)-Ref(C,-1);
minmax := If(Cross(f1,0),1,If(Cross(0,f1),-1,0));
minmax;
If this is unacceptable then try formula below. It's still referencing two bars into the future but should at least fool the Explorer and your charts into plotting up to the last available bar (meaningless though the last two bars might be).
f1 := Ref(C,-2)+Ref(C,-1)-Ref(C,2)-Ref(C,1);
minmax := If(Cross(f1,0),1,If(Cross(0,f1),-1,0));
ExtFml("Forum.Sum",minmax,1);

Hi,
I am doing a derivative of the price to get max and min: a simple
formula is:
f1 := Ref(C,-2)+Ref(C,-1)-Ref(C,2)-Ref(C,1);
minmax := If(Cross(f1,0),1,If(Cross(0,f1),-1,0));
minmax;
The problem is that using a function like that, every indicator that
reference this formula stops 2 days before the last bar. I can see
adding the chart and look minmax; the major problem is that the
Explorer does not work too.
This is not the same in Tradestation or Amibroker. How can I get the
Explorer working till the last day?
Any help woulld be appreciated.
Ciao,
Stefano
