Correct. The OLDEST bar of data is bar = 0; The NEWEST bar of data is
bar = BarCount - 1; You new code would be correct except I = barcount -
6 would be the 5th bar before the end (because first bar = 0).
Your error might have been trying to reference array[i-1] thinking you
had the most recent 5 bars.

Terry,
you mean that if i<5, it set for the first 5 bars. In other word, if
I want to set the latest 5 bars, I should use
for ( i=barcount-5; i< barcount; i++ ) { ... }; ?
I did have error when i use i<5, but anyway, I may be for other
reason.
thanks,
