Thanks Terry..
But I need to do this during an "Explore"
My long term averages are 30 days and would not work (I don't think)
I think it has to be done in a function. I have another qualifier
that I only want to test 10 days back.
I did eliminate close[0].
Do you know know why close[1] and close[2] don't give we what I
expect?
Thanks
