Closing prices

39 closed sessions on record, 12 August to 6 October UTC — 56 calendar days. 18 days in that window were not a trading session and are not drawn — the tape keeps polling a closed market and returns the last close, which is a reading and not a day's trading. Nothing here is backfilled — the record begins when this site began watching.

Each bar is that session’s high and low; the line joins the closes. The right-hand labels are the window’s own high, its low and the last close, so a line that fills the box may be a fraction of a per cent — where two of them land on the same line, the last close is the one shown.

The tape

818 readings over the last 68 hours. Readings, not ticks — this is what the site observed, and every dot is one observation. The gaps are real: where the poll did not return, there is no dot and the line is this site joining what it saw.
