Troubleshooting: Common Issues and How to Fix Them

Most AlertaChart issues fall into a handful of categories: stale data, missing notifications, lost drawings, or sign-in glitches.

Chart shows "Failed to load historical data"

1. Network: refresh once (Cmd-R / pull to refresh). 2. The symbol may have changed format. Try the spot version if you're on .p. 3. The data feed might be down. Check alertachart.com/status. 4. Slow connection: the chart auto-retries.

Watchlist row shows price but 0 volume

This usually only happens with equities. Price comes from the live WebSocket; volume comes from a periodic REST snapshot every 30 seconds. If the REST call failed, the row keeps showing the WS price but volume stays at 0 until the next refresh. Fix: pull to refresh on mobile, or click the row twice (away and back).

Alert didn't fire

Pro user, check: 1. Notification permission granted. 2. Device not on Do Not Disturb / Focus mode. 3. Alarm still in Active state. 4. Price actually crossed your level. AlertaChart fires on cross-through, not on close.

Free user: alarms only fire while AlertaChart is open. This is by design.

My drawings are gone

Drawings save to your device's localStorage by default. Not synced across devices unless you're a Pro user. - Same device, different browser? Drawings won't roam. - Cleared browser data? Drawings are gone. - New phone? Sign in with Pro; drawings sync down within seconds.

Can't sign in

1. Same auth provider (Google / Apple) you used to register. 2. On iOS: Sign in with Apple requires you to be signed into your Apple ID at the system level. 3. Browser cookies blocked? AlertaChart needs cookies for session. 4. Try Incognito / Private mode and sign in fresh.

Mobile app crashing

1. Update the app. 2. Force-close and reopen. 3. Restart the device. 4. Delete and reinstall. Your watchlist, drawings (Pro), and alerts restore on next sign-in.

Premium features greyed out after paying

1. Same account that bought the subscription. 2. Sign out and sign back in to refresh subscription state. 3. If still Free, contact support — we can manually re-verify with the App Store / Play Store on our side.
