   • Long: When you expect the asset price to **increase** \
   • Short: When you expect the asset price to **decrease**
4. Enter your starting amount (collateral)
5. Choose your leverage level
6. Set Take Profit/Stop Loss (optional)

Let's say you put in $500 (as collateral) and crank up the leverage to 5x - boom! You're now playing with $2,500 (minus a small bite for position costs).
