AlphaYouReal-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.
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) — nothing can fix that. Then there's the lag an app itself adds on top, between "publicly filed" and "you get notified" — that's the part worth judging an app on.
- "Real-time" is used loosely across the industry. The honest version: real-time on the alert, given whatever legal lag already exists on the underlying disclosure.
- 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.
Two Very Different Kinds of Lag
There's the lag built into the underlying data (Congress has 45 days by law; 13Fs are quarterly) — nothing can fix that. Then there's the lag an app itself adds on top, between "publicly filed" and "you get notified" — that's the part worth judging an app on.
Why This Distinction Gets Blurred in Marketing

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.
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).
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.
