Across this window the close ran between $1,143 on 14 September and $1,439 on 2 October. The line is the daily close over the same window: $1,219 on 8 September, $1,439 on 2 October. Of those days, 19 were trading sessions and the other 11 are hatched on the chart. On 8 of them no session took place, and the last close before it is carried forward rather than plotted; on 2 of them no session took place, and this window holds no earlier close to carry forward; on 1 of them we hold no close at all, which is a gap in our own record rather than a closure we can prove.
