Why was I signed out on another device?

Your account holds one active platform seat. When you sign in on a second device, it takes the seat and the older session is signed out. That's the normal way to move between your desktop and laptop, not an error.

Separately, our market-data agreements require us to detect accounts being used from multiple locations at once. An account flagged for simultaneous use can be locked for a minimum of 24 hours. If you're locked out, contact our Support Team.
