Opening a Long Position

1. Navigate to the Trading page
2. Select BTC/USDT pair

3. Choose:

   • Contract type: Perpetual
   • Margin: USDT-Margined

4. Configure:

   • Margin mode (Cross/Isolated)
   • Leverage (up to 125x for BTC)
   • Order type (Limit recommended)

Key Considerations:

• Cross margin uses entire account balance; Isolated limits risk to position margin
• Higher leverage amplifies both potential profits and liquidation risks

Understanding Contract Fees

• Taker Fee: 0.05% (removes liquidity)

Fee calculation example:

Fee = Contract Value × Fee Rate
Contract Value = Quantity × Contract Multiplier × Entry Price
