Example
If Bob deposited 100$, select BTC/USD and set x10 leverage → the position size is 1000$.
Bob thought BTC will pump in the near future and decided to open a Long position at $100,000.
If BTC price reaches $110,000 (+10%), the position value increases from $1000 to $1100 → his profit will be $100$ (100% of your initial margin)
If BTC price drops to $95,000 (- 5%), the position value decreases from $1000 to $950 → his loss will be $50 (-50% of your initial margin)
Bob thought BTC price will drop in the near future and decided to open a Short position at $100,000.
If BTC price drops to $95,000 (-10%), the position value increases from $1000 to $1100 → his profit will be $100$ (100% of your initial margin)
If BTC price rises to $105000 (+ 5%), the position value decreases from $1000 to $950 → his loss will be $50 (-50% of your initial margin)
