What Is Mark Price in Futures Trading?
Mark price serves as a reference price used to calculate unrealized profits and losses and determine liquidation levels for open positions. It is designed to provide a more stable price metric compared to the last traded price on the exchange.
- Key Features of Mark Price**:
1. **Prevents Manipulation**
- Ensures fair calculations by reducing the impact of sudden price spikes or crashes.
2. **Risk Management**
- Used to trigger liquidations when margin levels fall below requirements.
3. **Continuous Updates**
- The mark price is updated frequently based on real-time market data.
Example: If the last traded price of Bitcoin futures on an exchange is $30,100 but the index price of Bitcoin is $30,000, the mark price might be calculated at $30,050.

- Adjusts the mark price to account for the cost of holding long or short positions.
3. **Moving Averages**
- Smooths out sudden price movements for a more stable calculation.
- Example Calculation**:
Mark Price = Spot Price Index + Funding Rate Adjustment
