1. What Is Margin in Futures Trading?
In cryptocurrency futures markets, margin refers to the percentage of a futures contract's value that traders deposit to open a position. It acts as collateral to cover potential losses.
Key Concepts:
- Initial Margin: Minimum deposit required to open a position.
- Maintenance Margin: Minimum balance needed to keep a position open.
2. Margin Calculation Methods
OKX offers two margin modes:
A. Cross Margin Mode
- Shared across all open positions.
- Reduces liquidation risk by pooling resources.
Formula (Crypto Contracts): Initial Margin = Contract Size × |Contract Count| × Multiplier / (Reference Price × Leverage)
Formula (USDT Contracts): Initial Margin = Contract Size × |Contract Count| × Multiplier × Reference Price / Leverage
B. Isolated Margin Mode
- Dedicated per position for precise risk control.
Formula (Crypto Contracts): Initial Margin = Contract Size × |Contract Count| × Multiplier / (Average Open Price × Leverage)
Formula (USDT Contracts): Initial Margin = Contract Size × |Contract Count| × Multiplier × Average Open Price / Leverage
3. Margin vs. Leverage: The Relationship
Leverage amplifies both gains and risks by allowing traders to control larger positions with less capital.
Example (BTC/USDT):

- 10× Leverage: Requires 10% initial margin.
- 20× Leverage: Requires 5% initial margin.
4. Margin Requirements Breakdown
| Requirement Type | Description |
|---|---|
| Initial Margin Rate | 1 / Leverage (e.g., 10% for 10× leverage) |
| Maintenance Margin | Minimum balance to avoid liquidation. |
| Margin Level Calculation | (Equity / (Maintenance Margin + Liquidation Fees)) × 100% |
5. Managing Margin Calls
- Cross Margin: Auto-balances using pooled funds.
- Isolated Margin: Requires manual top-ups for specific positions.
Pro Tip: Increase isolated margins to reduce liquidation risks.
6. Adjusting Leverage Dynamically
- Increase Leverage: Lowers margin requirements (if within allowed limits).
- Decrease Leverage: Raises margin requirements (requires sufficient funds).
7. Order Loss in Futures Trading
System calculates unrealized losses if order prices deviate from reference prices.
Formulas:
- USDT Contracts:
Loss = |Contract Size × Contract Count × Multiplier × Min[0, (Reference Price − Order Price)]| - Crypto Contracts:
Loss = |Contract Size × Contract Count × Multiplier × Min[0, (1/Order Price − 1/Reference Price)]|
