Do Alerts/ notifications work if you log into a different broker?

[Myles Crouch-Anderson]

For example,

1. on broker A: i set an alert on VIX

2. i log into broker B who DOESNT offer vix.

I notice that the alert is still registered, but will it work if i remain logged into broker B?

So basically, is the alert SET on 'broker A - Vix' REGARDLESS of what i do? Like if my PC is off will the notification still work?

Thanks
