What’s the difference between unrealized and realized PnL? Don’t worry, your class rep is here to explain:
With 10x leverage, a 5% price increase means a return of about 50% on a long position; conversely, a 5% price drop means a return of about −50%.
In cross-margin mode, unrealized profits are also included in your margin balance, helping other positions weather volatility. When the price pulls back, that support shrinks too.
It took me a lot of tuition fees to learn this: read the rules first.
