A month-to-date calendar showing which OTC name led share volume on each individual trading day.
A daily board tells you who led one session. It cannot tell you whether that was the fourth time this month or the first. The calendar puts the month on one grid so rotation becomes visible: how many different names have taken the top spot, which ones keep coming back, and whether the month has been one name's month or twenty names'.
An opening sentence, then the repeats line, the highest-volume day and the lowest-volume day. The opening sentence changes each week and says only what the month's own figures support.
One unique leader across many sessions describes a month one name owned. Fifteen unique leaders across seventeen sessions describes a month where the top spot changed hands almost daily. Those are genuinely different markets and the sentence says which one it was.
The same OTC Markets session data behind the daily volume board, one month of it.
The repeats line is the most useful thing on the asset. A ticker that has led share volume on six separate days this month has held attention across the month, not just spiked once. That is a different fact from any single day's board and it is not visible anywhere else on the calendar.
