The stock signal desk
Understand the signal.
Know its limits.
A green result, a late alert and a weekend restock each raise a different question. These guides connect those questions to dated inventory evidence, with clear boundaries around what the feed can tell us.

What these guides measure
The data comes from recorded pickup observations, not physical stock counts, shipment records or private Apple orders. Each live panel identifies its country, model or store scope, time window and limitations. Missing observations remain unknown.
