Tiger Brokers liquidates positions without email notification, only sending push notifications secretly through the app. Unless you're constantly monitoring the app, you won't see them. This isn't the first time; I requested email alerts months ago, and you said you'd report it to your superiors, but nothing happened. Is setting up email alerts really that difficult? Furthermore, the risk warnings are very inexplicable. I clearly have cash in my account; I haven't even used margin. Is it really necessary to resort to liquidation?
