This chart in words

The chart plots daily Reddit mentions of ALT over the 30 days to 21 August 2026: 8 in total, busiest on 17 August with 3, and 3 on the last day counted. The line is the daily close over the same window: $2.84 on 23 July, $3.13 on 19 August. Of those days, 20 were trading sessions and the other 10 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 we hold no close at all, which is a gap in our own record rather than a closure we can prove.
