Pre-market & after-hours stock alerts by email
Most market-moving earnings reports and breaking news happen between 4:00 AM and 8:00 PM ET — long before the opening bell or after the closing bell. Computo monitors extended sessions continuously so you never miss an entry.
TL;DR
Real-time alerts outside regular hours. Coverage from 4:00 AM to 8:00 PM Eastern Time. Built-in cooldowns prevent inbox flooding. No broker credentials required.

Why regular-hours alerts fail when it matters most
Earnings reports drop at 16:05 or 07:00 ET. By the time the 09:30 ET opening bell rings, the stock has already gapped 10% up or down. If your broker app only checks prices during regular market hours, you find out too late. Computo actively monitors prices across pre-market (04:00–09:30 ET) and after-hours (16:00–20:00 ET).
Full extended session coverage: 4:00 AM to 8:00 PM ET
Whether it is an early European session gap, an FDA announcement at 06:30 ET, or big tech earnings at 16:05 ET, Computo tracks real trades and sends a clean email alert the second your target level or percentage move is breached.
Smart cooldowns: Signal, not spam
Low liquidity in extended hours can cause rapid bids and asks around a price level. Computo applies an automatic cooldown (configurable, default 60 minutes) so you receive one clear signal, not 40 repetitive emails.
Read-only: Zero account access
Computo watches public consolidated market data. We never ask for your broker username, password, or API token. There is nothing to authorize, nothing to link, and nothing we can touch.
