Cooldowns, quiet hours, and the daily limit
A cooldown, quiet hours, and the daily limit all reduce messages. They do not do the same job. A cooldown is a wait on one alert. Quiet hours are a clock for the account. The daily limit is a count of alerts sent today.
This page says what each control does. It does not say a move will continue, and it does not tell you to buy, sell, or hold.
A cooldown is a wait on one alert
The screen calls it "Wait before it can fire again." After the alert fires, we wait that long before it can fire again.
The choices are 15 minutes, 30 minutes, 1 hour, 4 hours, 12 hours, 24 hours, and 7 days. The usual wait is 1 hour for a price alert, a percent move, and a volume spike. An unusual move usually waits 4 hours. The wait belongs to that alert, and to each coin it watches. It is not a pause for the whole account.
Firing and becoming ready again are separate. A fire clears the armed state and starts the wait. The alert can arm again during the wait, once its own re-arm condition is true. It still does not fire until the wait is over, and it does not fire in the same check that arms it. Both have to allow the next fire.
A price that stays past your level fires once. It fires again only after the price moves back and then crosses the level again, and not before the wait ends. Percent moves, volume spikes, and unusual moves have their own re-arm rules. The wait sits on top of those rules.
Mute and snooze are separate. The alert still runs, Today still records the fires, and the messages do not go out.
Quiet hours pause sending on a clock
Quiet hours are off until you turn them on. The preset is nights, 10:00 PM to 7:00 AM, in your time zone. Start and end are every 30 minutes, and they have to differ. The same time is refused.
The window includes the start and stops at the end. When the start is later than the end, it crosses midnight. 10:00 PM to 7:00 AM is that shape: 22:00 included, 07:00 excluded. The default zone for a new account is US Eastern, until you change it. Changing the zone changes the clock for the whole account.
During quiet hours the alert is still recorded on Today. It is not sent then. The badge is "Held for quiet hours." Turning quiet hours on does not change your alerts or your receipts.
A price-above or price-below alert can send once when quiet hours end, if the price is still across your level. Only the newest fire for that alert and coin is sent. It is not sent if you muted it, snoozed it, edited the level, or have nowhere to send it. It is not sent if that fire is more than 24 hours older than the end. If the daily limit is already used when the clock ends, the limit applies instead.
Percent moves, volume spikes, and unusual moves do not pile up. They stay on Today. They are not sent when the window opens.
The window follows the wall clock. If your end time falls in the hour that spring forward skips, quiet hours end when the clock jumps. If the end time happens twice on the fall-back morning, quiet hours end the first time. If the clock then moves back into the window, it is quiet again until the end time comes around once more.
The daily limit counts alerts sent
The screen calls it the daily message limit. The field is messages per day. The default is 8. You can set a whole number from 1 to 30. Outside that range, the field asks you to choose 1 to 30.
The count is alerts sent, not destinations. One alert that goes to Telegram, phone alerts, and email counts as one. A test message does not count. The morning brief does not count. An alert with nowhere to send does not count, and it is not kept back for the limit.
The day is your local calendar day. It resets at local midnight. On a morning the clock changes, that day can be 23 hours or 25 hours. A price alert recorded during quiet hours counts on the day it is sent, not on the day it fired.
The first alert that would pass the limit sends one notice. Further alerts stay on Today and in your next brief. Later alerts that day send nothing else. They are still written on Today. Deleting an alert does not give those messages back. Alerts already sent still count.
Each control answers a different question
The cooldown asks when this alert may fire again. Quiet hours ask whether a message goes out at this clock time. The daily limit asks how many alerts this account has already sent today.
A fire can be recorded and still not sent. If it never fired, look at the wait. If Today shows it and no message went out, look at the clock and at today's count.
Terminal keeps the cooldown on the alert, quiet hours on the clock, and the daily limit on messages sent, and it still records a fire on Today when a message does not go out.
FAQ
Does the cooldown replace quiet hours?
No. The cooldown blocks a new fire until the wait ends. Quiet hours can pause delivery of a fire that already happened. A price alert recorded overnight can still send once at the end, if the price is still across your level and the other checks pass.
Does one alert to three places use three messages?
No. Telegram, phone alerts, and email for the same alert count as one. The daily limit counts alerts sent, not each destination.
Do quiet hours erase the alert?
No. Today still records it. Turning quiet hours on does not change your alerts or your receipts. Percent, volume, and unusual-move alerts are not sent later as a pile. A price alert can send once at the end, and only if it is still true.
