Johan,
I certainly agree with you but I tried to avoid the very first bar.
The reason was the Martins definition for pivothigh/pivotlow.
If you see, for example the
pivotlow = Ref(L,-1)>L AND L<Ref(L,1);
has two parts : The first Ref(L,-1)>L is well defined from the
second bar [because of the ref function, but, the second part L<Ref
(L,1) looks into the future and it is well defined from the very
first bar. So, what would be the meaning of an {EMPTY} AND TRUE
relation ?
IMO, it should be {EMPTY}. AFL behaves like {EMPTY} AND TRUE =FALSE
which is out of my understanding.
Try the very first bar of
f=Cum(1);
pivotlow = Ref(f,-1)>f AND f<Ref(f,1);
Plot(Ref(f,-1)>f,"first part",2,1);
Plot((f<Ref(f,1)),"second part",4,2);
Plot(pivotlow,"AND",5,1);
GraphXSpace=5;
