use case

Build a custom watchlist and get alerted only on what you track

A watchlist is only useful if it tells you when something on it moves — otherwise it's just a list you have to remember to check. The gap between "I'm tracking this" and "I know the moment it changed" is where most things slip through.

x-signal closes that gap. You build a custom watchlist, attach triggers to it, and let real-time alerts do the checking. This page is about turning a passive list into an active early-warning system.

onlywhat's on your list — nothing you didn't ask for

From a list you check to a list that tells you

Manually checking a watchlist is unreliable by nature — you'll check too often when nothing's happening and not at all when something is. Attaching triggers flips the relationship: the list watches itself and reaches out only when one of your items crosses a line you set.

Because the triggers are yours, the alerts are relevant by construction. You're not subscribing to someone else's idea of important; you're defining it.

Tuning a watchlist that earns its alerts

The best watchlists are specific. Broad triggers fire constantly and train you to ignore them; tight, well-chosen conditions keep every alert worth opening. Start narrow, and widen only when you find you're missing things — the opposite of how most people set up notifications.

how it works

  1. 01

    build your watchlist

    Add the items, feeds, or signals you want to keep an eye on.

  2. 02

    attach triggers

    Set the conditions that make each item worth an alert.

  3. 03

    stay ahead

    Get pinged in real time the moment something on your list moves.

frequently asked

Can I have more than one watchlist?
You can track the set of things you care about and tune triggers per item, so different parts of your list can alert on different conditions.
What kinds of things can I watch?
The feeds and sources you connect — x-signal watches them against the triggers you define.
How do I avoid alert fatigue?
Keep triggers specific. Narrow conditions mean fewer, more meaningful alerts you'll actually trust.
