Tomasz,
Below defined s is a string :
s=WriteIf(StochD()<30,"o/s",WriteIf(StochD()>=30 AND StochD()
<70,"congestive","o/b"));
with 3 "values"[to call somehow the result of s].
In AA, AFAIK, we can not see these "values", the exploration
s=WriteIf(StochD()<30,"o/s",WriteIf(StochD()>=30 AND StochD()
<70,"congestive","o/b"));
Filter=1;
AddTextColumn(s,"");
for all quotations will give "o/b" or "congestive" or "o/s" according
to the last s value.
In commentary window, the same s will give the proper value per day.
I want to read in the same commentary a result like
^NDX today is o/b
Yesterday was congestive .
I have one solution that works fine
Name()+" today is "+WriteIf(StochD()<30,"O/S. ",WriteIf(StochD()>=30
AND StochD()<70,"congestive. ","O/B. "));
"Yesterday was "+WriteIf(Ref(StochD(),-1)<30,"O/S. ",WriteIf(Ref
(StochD(),-1)>=30 AND Ref(StochD(),-1)<70,"congestive. ","O/B. "));
and I thought if it is possible to have a simpler "Ref(s,-1)" for the
previous "value" of a string s.
