Hi Everyone,
It’s important to note that under normal market conditions, most brokers have monitoring systems in place that will automatically close your trade once your account falls below the minimum margin requirement. This is to reduce the chances that your account balance goes negative.
That said, you do risk incurring losses greater than your account balance, especially during periods of extreme market volatility. You might find this earlier discussion helpful to understand how this could happen: Can I lose more than my deposit?
