Can I lose more money than my deposit?
With Trading 212 your loss is limited to the amount in your account. At many brokers this is not the case.
Why are my positions closed?
Your positions may be closed by the platform automatically in order to prevent you from losing more money than you have in your account.
How can I limit my loss?
You can do so by putting a Stop Loss Order on every position. This will keep your risk at an acceptable level to you.
