Trading Agent Command Center
The Command Center is a private web app. One person, its owner, uses it to review the status, reports and proposals of his own options-trading agent.
It is not a public service. There is no sign-up, and nobody else can open it.
How sign-in works
The Command Center sits behind Google Cloud Identity-Aware Proxy. Opening it starts a Google sign-in, and only the owner's approved Google account is let through. The app then asks for its own password and authenticator code.
