Hi Steve, 

Thanks for your post..

But I need to do this during an "Explore" Thus I think I have to do 
this in a function. My long term averages are 30 days and would not 
work (I don't think). 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
BobL
