Hi Spyros! Back again!
Well your new formulation seems to work fine for most dates, but
fails for each day of December of each year up until 2001 (I didn't
really check why!).
Now ... I do have a suggestion that might do the trick:
build numbers that represent complete dates 'positionally' (that is,
transforms, say, Nov 25, 2001 into 20011125).
There it goes:
d:=Input("Day",1,31,1);
m:=Input("Month",1,12,1);
y:=Input("Year",1920,2030,2002);
mydate:= 10000*y + 100*m + d;
date:= 10000*Year() + 100*Month() + DayOfMonth();
count:=BarsSince(mydate<=date); {use '<' if first day is not to be
counted}
count:=count + Cum(If(count=0,1,0));
count
Looks nice, doesn't it? Better yet, seems to work! :-D
Would you care to verify it?
Thanks for your enlightening insights!!! Take it easy.
