Get an email when something breaks

Checking once is easy — noticing when things drift is the hard part. Tell us what to watch in plain English. Every monitor is reviewed by a real person before it goes live, so it does exactly what you meant.

What should we watch? Where should the alert go?

Your first alert is free. No account, no spam — just the alert you asked for.

Things people watch

Overlap between my two ETFs drifts above 30% One stock quietly becomes 8% of my whole portfolio NVDA max pain moves 5%+ before Friday expiry SPY gamma exposure flips negative My tech weight runs 10 points hotter than the S&P

Anything on this site — fund overlap, sector drift, max pain and GEX — is watchable. If we can compute it once, we can watch it for you.

How it works

You write the condition in your own words. A real person reads it, sets up the check against the same official data that powers this site, and replies within 24 hours confirming exactly what we'll watch and how often. When your condition breaks, you get one email. That's it — no dashboard to babysit.
