Does it support customers from outside the US? (Robinhood doesn't..)
Ameritrade. I’ve only lived in the US so I’m not sure... I doubt they would geographically lock the app though
Depends where you are. QuestTrade is good for Canada. Most US brokerages aren't allowed to hold accounts for Canadian residents. So Fidelity and TD in Canada are basically completely seperate from their US counterparts.
Interactive Brokers will accept foreign customers
