Alerts notify you when a market hits a condition you define — a price target, a score shift, breaking news, or a volume spike. You choose the market, the trigger, and how you want to be notified.

​
Creating an alert

1

Open the alert creation form

You can create an alert from two places:
  • Alerts tab → tap Create Alert at the top.
  • Market detail page → tap the Create Alert button in the actions row. The market is pre-filled.
2

Select a market

If you didn’t come from a market detail page, search for and select the market you want to monitor.
3

Choose a trigger type

Pick what condition should fire the alert:
  • Price threshold — When the price goes above or below a value you set.
  • Score shift — When the AI confidence score changes by a specified amount.
  • News catalyst — When a high-impact news article is matched to the market.
  • Volume spike — When trading volume surges above its recent baseline.
See alert types for details on configuring each trigger.
4

Select delivery channels

Choose how you want to be notified:
  • Push notification — Sent to your phone or browser (requires notification permissions).
  • Email — Sent to your account email.
  • In-app — Appears in the Alerts tab with an unread badge.
You can enable multiple channels for the same alert.
5

Save the alert

Tap Create. The alert starts monitoring immediately.

​
Managing alerts

​
Viewing alerts

The Alerts tab shows two things:
  1. Alert events — Notifications from alerts that have fired. New events show an unread dot.
  2. Alert rules — Your configured alert rules and their status.

​
Editing an alert

Tap an alert rule to open it. You can change the trigger conditions, delivery channels, or pause it.

​
Pausing and resuming

You can pause an alert rule without deleting it. Paused alerts stop evaluating until you resume them.

​
Deleting an alert

Swipe left on an alert rule (mobile) or use the delete option to remove it permanently.

Alerts are also rate-limited to 20 notifications per day per account to prevent notification fatigue.

​
How alerts are evaluated

Previa evaluates your alert rules periodically. When a rule’s conditions are met:
  1. A notification is created and delivered via your selected channels.
  2. The alert event appears in your Alerts tab.
  3. If you set a max trigger count, it’s decremented.
  4. If the alert has an expiration date and it’s passed, the alert is set to expired.
