Yahoo 30m/1h can print through Saturday; those opens added index steps
while 1m display is one slot, kinking the line at 17:00. Short holes
and settlement compression are unchanged.
Alerts get a number, assigned server-side and shown in both the push and the
Events list, so a notification on a phone can be matched to a row on a screen
when several fire together. It could not come from the browser: that counter
restarts on reload and differs between tabs. It is persisted next to the
cooldown state, because numbering restarting after a deploy would collide with a
phone's existing notification history — which changed that file from a list to
an object, with the loader still reading the old shape.
Pushes now carry a timestamp in the configured zone rather than the server's.
ALERT_TIMEZONE defaults to America/Chicago; containers run UTC, and a push
reading 02:14 to someone seeing 21:14 costs a translation every time. The
browser already formats its own times locally and is unchanged.
Confluence zones are one line each, ordered by price rather than by proximity,
so the list reads top to bottom the way the chart does and all of them fit on
screen — sixteen zones in 394px, about 25px each, where each previously took a
four-line block. Ordering is a display concern only: the server still returns
them nearest-first, which is what the alert path wants.

- Duplicate and delete from the line context menu.
- Copies shift ten bars right.
- Default names are up and down; copies become up 2, down 2, etc.
- Exact local data receipt time including seconds.
- Deployment timestamp removed.
- Test cleanup no longer deletes drawings created from your browser.
- JWT password session flow.
Alerts were evaluated inside the WebSocket handler, with a separate AlertEngine
per connection. Three consequences, all of which defeated the point of phone
push:
- No browser connected meant no alert at all. The notification only existed if
a tab was open to receive it, which is precisely when you least need it.
- Two tabs meant two notifications, since each connection evaluated
independently.
- Cooldowns lived and died with the connection, so reloading the page cleared
them and a zone that had just alerted alerted again at once.
The third also meant the calibration in the README described a system nobody was
running: it models a single engine, which is what this now is.
Evaluation moves into Runtime, once per closed 1m bar, over every level. Layer
preferences are deliberately not consulted — they are a display choice made in
one browser, and a push notification should not depend on which checkboxes that
browser has ticked. Sockets now only relay what the runtime produced.
ntfy dispatch is a detached task with its own error handling. It previously ran
inline in the socket loop and called raise_for_status(), where the only except
clause caught disconnects — so a transient ntfy outage dropped the client's
connection.
Delivery verified end to end against ntfy.sh: title, priority and the multi-line
body all arrive as intended. NTFY_TOPIC still has to be set for anything to send.

The confluence engine had nothing to work with. Daily moving averages were the
only level source, and they sat 163 to 697 points from price, so every cluster
had exactly one member and no alert could ever fire.
Two new sources, chosen for having a real following — the engine is a bet that
many participants watch the same price, which is what makes a level hold:
- Prior day high/low/close, from the last *closed* daily bar so mid-session the
levels do not silently switch to today's own developing range. Full daily
weight rather than the 0.75 average discount: a traded high is structure, not
a derived average.
- Session VWAP, anchored to the 18:00 ET open like the daily bars. Institutional
execution is benchmarked against it, and zero-volume overnight minutes are
skipped rather than dividing by zero.
Both are stamped 1d, so they get their own colours to stay distinguishable from
the daily averages. Prior-day levels draw as price lines, which span the chart
and label the axis instead of relying on bar-index interpolation.
VWAP re-prices every minute while a daily average carries hundreds of points and
changes once a session, so broadcasting the whole level set on the VWAP cadence
would have pushed the entire history every minute. Levels now go out as a delta
that clients merge by id.
Adding the levels then exposed two defects that had been invisible while nothing
could cluster:
- Cluster identity was sha1(side + round(center / tolerance)), and tolerance
derives from ATR, so it changed every bar. The same zone was continually
issued a new id, never matched the cooldown table, and the cooldown did
nothing. Identity is now the set of converging levels.
- Alert suppression keyed on that identity, so a level drifting in or out of a
group read as a new zone. It now suppresses by proximity: two zones within an
ATR are the same zone, and the strongest is the one reported.
Over six replayed sessions at threshold 28 that is 247 alerts, then 54, then 40;
raising the cooldown to 4h — which only affects repeats of the same area, never
a genuinely new zone — gives 17 total with a worst session of 9.
calibrate_alerts.py now sweeps threshold and cooldown together in one pass,
since the threshold turns out to be quantised and nearly useless as a control.
