Real-Time vs. Delayed Stock Alerts: Why the Lag Matters
Why some stock alerts arrive instantly and others are delayed by hours or days - and how to tell which one you're actually getting.
The plan was marketed as "real-time" so you'd never be the last to know. Then a filing shows up six hours after it was public, and the obvious question arrives: what did "real-time" actually mean on that pricing page? Being annoyed here is fair. That word was sold as a guarantee, and it isn't one.
Direct answer"Real-time" should mean the alert fires the moment the underlying event (a filing, a price cross) becomes public - not the moment a human curator gets around to writing it up. Many "real-time" claims quietly mean same-day, not same-minute.
- There's the lag built into the underlying data (Congress has 45 days by law; 13Fs are quarterly), and nothing can fix that. Then there's the lag an app itself adds on top, between "publicly filed" and "you get notified." That second lag is the part actually worth judging an app on.
- "Real-time" is used loosely across the industry, often on purpose. The honest version: real-time on the alert, given whatever legal lag already exists on the underlying disclosure. Anyone who skips that clarification is hoping you won't ask.
- Ask, or test, how long after a filing goes public an app actually sends its alert - minutes, or hours. That gap is where competing apps genuinely differ, and it's the one number most of them don't advertise.
Two Very Different Kinds of Lag
There's the lag built into the underlying data (Congress has 45 days by law; 13Fs are quarterly), and nothing can fix that. Then there's the lag an app itself adds on top, between "publicly filed" and "you get notified." That second lag is the part actually worth judging an app on.

What to Actually Check
Ask, or test, how long after a filing goes public an app actually sends its alert - minutes, or hours. That gap is where competing apps genuinely differ, and it's the one number most of them don't advertise.
How AlphaYou Handles This
Alerts fire as close to the moment of public filing as the source data allows, and we're explicit about which data types (like congress trades) carry a built-in legal lag versus which don't (like Form 4), so you know exactly what "real-time" means for each one.
FAQ
Is any stock alert truly instant?
Only relative to when the underlying data becomes public - some data types (like congress filings) have a legal reporting lag no app can bypass.
How do I know if an app's "real-time" claim is honest?
Check how long after public filing the alert actually arrives, not just the marketing label.
