How COST price alerts work
Pick a target price or a % move for COST. Computo watches the market — including pre-market and after-hours sessions — and notifies you the moment it triggers, then waits out a cooldown so you are never spammed. So you do not have to refresh the COST live price all day to catch a move; set it once and we email you.

COST price alerts — FAQ
- Is a COST price alert free?
- Yes, for your first 14 days. Creating a COST price alert on Computo starts with a free trial — no credit card required. After the trial, keep unlimited alerts, personal notes, and portfolios for $5/month or $50/year.
- How do the price alerts work?
- Computo watches COST during market hours and notifies you the moment your target price or % move is hit, then waits out a cooldown so you are never spammed.
- Do I need to install an app?
- No. Computo runs in your browser. Create a free account, set your alert, and we handle the monitoring — there is nothing to install.
- Can I set a target price or a percentage move for COST?
- Yes. Set an absolute price (for example, alert me when COST crosses USD 1,096.50) or a daily percentage move (for example, alert me if COST drops 1.5% in a day).
- What is the COST after-hours price?
- When COST is trading in the after-hours session, the live price at the top of this page is the after-hours price, with the regular-session close shown for reference. After-hours runs roughly 4:00–8:00 PM ET. Set a free alert and Computo emails you when COST hits your target — even outside regular hours.
- Does COST trade pre-market?
- Yes. COST trades in the pre-market session before the regular open. When pre-market is active, the live price above is the pre-market price for COST. Set a free price alert and we notify you the moment your target is hit, pre-market included.
