I said to remove ALL subscripts [0] [1] [2] [n]
These refer to a SINGLE BAR of data.
You will simply have:
Filter = 1;
AddColumn(Close, "Close");
Then use my suggestion below, which is the same as Steve's:
> You can also Explore just the last 15 days in AA
> by setting last n days to 15, and set Filter = 1;
ARRAYS contain ALL BARS of DATA for the current Symbol
C[0] = the very first bar of data
C[1] = the second bar of data
C[n] = the nth bar of data
C[barCount - 1] = the very last bar of data.
This type of code is (generally) ONLY useful in looping.
EXPLORE NEEDS ARRAYS, the the code above.

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
