How noisy the alerts are, counted.
Every alert is a claim about a fact: a price crossed a level, a name entered the board, a grade moved. This page counts those claims by kind and by month in New York time: how many fired, how many were followed within 10 trading sessions by their opposite, and how many were withdrawn because a feed corrected the number underneath. Alerts that turned around are counted here, not left out.
This page is public, so it shows aggregate counts and nothing else: no symbol, no member, no row for anyone. A count is printed only when it is at least 5 and the alerts behind it came from at least 3 different members; otherwise the cell reads “not shown — too few alerts or members”, and that includes zero. So no single member’s activity can be worked out from a cell. No totals are printed, because a total minus the printed cells would give a hidden one back.
An alert counts as followed by its opposite when the same member’s alert of the same kind, on the same name and with the same numbers, fired the other way within 10 trading sessions after it (weekends and market holidays are not sessions). An opposite can only fire for a member who set it up, so this count is a floor. “Window open” counts alerts whose 10 sessions have not all closed; their reversed count can still grow. A deleted account takes its alerts with it, so a past month can fall.
By month and kind
Withdrawn: No withdrawal is recorded yet. When a feed corrects a number after an alert has fired, nothing in the alert tables marks that alert withdrawn: a price alert keeps its fired time and price, and an event keeps its sentence. Until a withdrawal is written at the moment it happens, this column is left empty rather than filled with a count nobody recorded.
What counts as the opposite
These kinds have no opposite, so the reversal column reads “no opposite” for them: volume multiple, a call resolved, earnings ahead, ex-dividend date ahead, split ahead, screen baseline set. A resolved call, a date ahead and a baseline are statements about something that happened once; nothing turns them around.
