Why does Client Portal (Web) say "You are currently logged in without Trading/Market Data permissions"?

This message appears when the same username already has an active trading or market data session open on another platform. A username can only have one active trading and real-time market data session at a time. For example, if the client is already logged in to a trading platform or MEXEM Mobile and then opens Client Portal, Client Portal may allow account management access only, without trading or real-time market data permissions. The client can still use Client Portal to manage the account, but trading and real-time market data will remain active on the other platform. To enable trading and market data access in Client Portal, the client can select “Log in with Trading/Market Data”. This will transfer trading access to Client Portal and disconnect the trading session on the other platform.
