Arbitrum price alerts, set from how ARB actually moves
An Arbitrum price alert watches ARB and messages you when it hits a level or moves by a percentage you choose. Arbitrum moved 2.28% on a typical day over the last 365 days — roughly 1.9 times Bitcoin's typical day, so Bitcoin's thresholds are too tight for it. On one day in ten it moved more than 7.75%, and its worst single day in the window was 34.34%. On that record, an 8% 24-hour alert fired about 2.7 times a month — rare enough to still be worth opening. CoinPriceAlert checks the condition on its servers, so it arrives with the app closed, free for 3 alerts.

What threshold should Arbitrum use?
Arbitrum moved 2.28% on a typical day over the last 365 days — roughly 1.9 times Bitcoin's typical day, so Bitcoin's thresholds are too tight for it. On one day in ten it moved more than 7.75%, and its worst single day in the window was 34.34%.
That is the number the threshold should come from, because an alert that fires on an ordinary day is one you learn to dismiss — and then you dismiss the one that mattered. The table below is an audit rather than a forecast: for each threshold it counts the days in the last 365 whose move exceeded it, which is exactly what a 24-hour percentage alert measures.
| 24-hour threshold | Fires per month | Fires per year |
|---|---|---|
| 2% | 16.2 | 197 |
| 3% | 12.4 | 151 |
| 5% | 6 | 73 |
| 8% | 2.7 ← rare enough | 33 |
| 10% | 1.6 | 19 |
| 15% | 0.5 | 6 |
| 20% | 0.2 | 3 |
| 25% | 0.2 | 2 |
| 30% | 0.1 | 1 |
The highlighted row is the tightest threshold that still fired three times a month or fewer for Arbitrum: 8%, about 2.7 times a month.
Look at the gap between the two ends of that table. Arbitrum's worst day was about 15 times its typical one, which is a fat tail even by crypto standards: most days are quiet and then one is not. A percentage alert is the right instrument for a coin shaped like this, because it fires on the shape of the move rather than on a level you had to guess in advance — and the days you actually want to hear about are precisely the ones a price level set last month would have missed.

Three ARB alerts worth setting
- Arbitrum rises above $0.1815 — 8% above today's $0.1681. It fires once, then re-arms only when the price crosses back and crosses again.
- Arbitrum falls below $0.1547 — the same distance underneath. If you hold ARB, this is the one that matters at 3am.
- Arbitrum moves 8% in 24 hours — direction-agnostic, and still the right alert wherever the price ends up.
Picking a ARB price level
Arbitrum trades in cents, at $0.1681, which means the obvious levels are the ones with a clean decimal: $0.2000 is 19.0% away. Those levels attract attention for no better reason than that they look tidy, which is exactly why other people's orders cluster there and why they are worth an alert.
Arbitrum is 93% below its all-time high of $2.39. A drawdown that deep means the old high is history rather than a target, and it also means percentage moves off a low base look dramatic without much money changing hands. That is a good reason to size the threshold from the table above rather than from instinct.
Where ARB has been lately
Over the last seven days Arbitrum is 11.0% down — more than the 8% a rare-enough daily alert uses, so this has been an eventful week by its own standards. It is down 0.53% over the last day.
Because 8% fires around 2.7 times a month on Arbitrum, think about where it lands before you set it. Push is right for the ones you would act on; Telegram is better for the ones you want to read later without a buzz. Quiet hours hold anything overnight until morning, and they are worth switching on for a coin that moves this often. Whichever you choose, the condition is evaluated on our servers rather than on your phone — and because the usual reason an alert app goes quiet is a revoked permission or a retired push token rather than the alert itself, the app checks that whole chain and names the broken link. Arbitrum's live chart, range and extended technicals are on its coin page if you would rather watch than be told.
Frequently asked questions
How do I set a Arbitrum price alert?
Open CoinPriceAlert, search for Arbitrum, and tap the bell on its row. Choose a price level — $0.1815 and $0.1547 are 8% either side of today's $0.1681 — or a percentage move, then pick push, Telegram or email. No account is needed to start.
What percentage should an ARB alert use?
Start from this coin's own record rather than a rule of thumb. Arbitrum moved 2.28% on a typical day over the last 365 days, so an 8% 24-hour alert fired about 2.7 times a month. Anything tighter fires most days and trains you to swipe it away.
Why does Arbitrum need a percentage alert rather than a price?
Because its worst day was about 15 times its typical one. On a coin with a tail that long, the days worth hearing about are the ones no level chosen in advance would have caught, and a percentage alert fires on the size of the move instead.
What price should I set an alert at for Arbitrum?
Arbitrum trades at $0.1681, so the decimals matter more than the number. The app shows any level back to you as a percentage of the current price before saving, which catches a misplaced zero. $0.2000 is the nearest tidy level above here.
How often will a ARB alert fire?
At 8% it fired about 2.7 times a month over the last 365 days. The table on this page shows every other threshold, so you can pick the frequency you want rather than discovering it afterwards.
Is the Arbitrum alert free?
Yes. The free plan covers 3 active alerts across every market in the app, with price and 24-hour percentage alerts, the home screen widget and the daily digest, delivered by push, Telegram or email, with no card required.
Do ARB alerts work when the app is closed?
Yes. Every alert is evaluated on our servers against a live price feed, not on your phone, so it fires whether the app is open, closed or swiped away. The app shows you when the servers last checked, so you never have to take that on trust.
