Bars are counted from 0 to Count.To access 10th bar within collection use the following syntax: bar = bars[10]; Often bars are stored in BarCollection in reverse order: bars[0] - most recent bar, bar[1] - previous bar,... BarCollection can be read-only.
If you will try to change elements of read-only collection NotSupportedException exception will be generated.
