Socrato,
There is a users manual in the group file section and a HELP icon in
your program. If you are not familiar with either of them let me
suggest that you take a bit of time to expose yourself to them.
That being said think of Ref(low,+1) as tomorrow's low. Data is
collected until the end of today. Nowhere is the value for tomorrow's
low collected...it is in the future. Yesterday's low is available
though and it is written as ref(low,-1).
>From what you have written it appears that you are looking for a
trailing stop. If that is so then let us know and we might be able to
get you something useable.
