[Perhaps your misunderstanding is the last day of your data.
As you see from gif, for that last day prices are equal.
Why?
Because, whithout data for tomorrow, the program gives for
ref(close,1) the available today?s price.
(In my opinion, it should indicate an {empty} value, because
ref(close,+1) exists for all previous days except the last one)
I do not know how it is designed, I know how it works.]
Anyway, the simple line for today?s close is
c1=c;
I hope this is more clear now.
Please note here that ref(close,+5), which is the close +5 days later
than examined day, has NOT ANY meaning for the last 4 days, no
matter if it is on your gaph and no matter if it gives you results in any
calculation. It SHOULD be handled with care.
